The road not taken.....musings on whooping cranes
I almost got involved with Whooping Cranes a long time ago, and I wish I had. When I finished college, I wrote off to somebody (I forgot his name, Ray? Roy?) who was managing a Whooping Crane recovery project in another state. He and his cohorts were using Sandhill Cranes to raise Whooping Crane eggs. The researchers had found that if they removed eggs from Whooper nests and slipped the eggs into the nests of Sandhill Crane foster parents, the Whoopers would simply lay replacement eggs. Thereby doubling the production of Whooper chicks per year at this recovery facility. The researchers used gloves fashioned to look like crane heads when they tended the babies, so the cranes wouldn't lose their fear of humans.
I wanted to work for this project helping an endangered species. But as fate would have it, Ray or Roy or whoever had no money to hire anyone else, was making use of volunteer labor, and I decided to do something else. That's the proverbial road I did not take, as Robert Frost wrote of in his famous poem The Road Not Taken. That decision was probably a big mistake on my part, given the situation I find myself in at present.
But I digress. To cut to the chase....I've always been interested in Whooping Cranes. They're making a significant comeback, and the story is pretty intriguing.
Way before people fouled up almost everything outdoors, the range of Whooping Cranes extended from the Arctic coast into Mexico, and from Utah to NJ. Their range included wintering grounds in the Carolinas, Georgia, and Florida. Then, because of hunting and habitat destruction, their numbers dropped to only 16 birds in 1941, all in one little flock that nested in Canada and overwintered in Texas. But by the 1970's and 80's, recovery efforts were well underway. Those efforts included raising Whooping Cranes in captivity as I mentioned above. Sandhill Cranes played a big part, standing in as surrogate parents and even surrogate flocks. In 1998, scientist Kent Clegg figured a way to teach some captive-raised Whooping Cranes how to migrate from Idaho to New Mexico. He trained them to follow an ultralight plane, and when they got to New Mexico, he got them to mingle with a robust Sandhill Crane flock, so they wouldn't be alone and would learn flocking behaviors.
Due to these and other recovery efforts, the western flock of Whooping Cranes has now expanded to about 270 birds, according the USFW Service. A big increase!
Recent events in the East have caught my attention, and motivated me to write this post. In 2001, the USFW Service began trying to reintroduce Whooping Cranes to the eastern part of the country, which has had no birds at all for a century or more. The Whoopers have been taught with another ultralight plane to fly from breeding grounds in Wisconsin to overwintering grounds in Florida, and back. It's amazing that the plane gimmick works - just like in the fictitious movie, Fly Away Home (about geese following an ultralight plane). But cranes are programmed genetically to follow something flying (normally their parents) to learn the ancestral migratory route. Somehow a slow quiet small plane will suffice.
As I mentioned, Whooping Cranes used to overwinter in the Carolinas as well as Florida. But the newly expanded population has never been trained to come here. However.....in early 2004, one group flying up from Florida, en route to Wisconsin, hit some strong winds that blew them east and they settled down near New Bern, on the coastal plain of NC. My home state. Two males of the original seven that put down here in 2004, along with their mates, continue to return to the ACE basin in South Carolina. The individuals are known as 10-03, I, and WI-06. Don't know the fourth one. I, for one, am delighted to have them here.
The total Eastern migratory population is only 73 Whooping Cranes, including the ones that go to Florida. That's a lot, especially when you consider we now have 343 in the whole country. Compared to the 16 we once had.
The Carolina coast is wild in places. I went with a USFW biologist once to see some red wolves, who roam freely on the NC coast, in the Alligator River Nature Preserve. Turned out the only wolves we found were some that were in a pen awaiting inoculations from the USFW staff. But over 100 now run free throughout the preserve, so I guess cranes can live here too.
Frost begins his poem with "Two roads diverged in a yellow wood". Although I have regrets about the road I didn't take, as an aspiring biologist years ago, I'm thrilled that a few cranes turned left one year, and now seem to prefer South Carolina to Florida. Maybe, if we're lucky, they'll thrive here.
Two roads diverged in a wood, and I—
I took the one less traveled by,
And that has made all the difference.

How to Buy a Used, Fuel-efficient and Green Car
We’ve been wanting to buy a more fuel-efficient car for some time, but, given our financial insecurities, we’ve been putting it off. Finally, we were forced into action when our 14-year-old Volvo was totaled in a December accident. The question was thrust upon us: what to buy as a replacement?

Fake firelogs burn cleaner than real wood
In Charlotte, temperatures will dip to 8 degrees tonight. That's very cold by my standards. This is the South! Just a couple of weeks ago, it was 65! When it gets really cold here, folks want to toss a log on the fireplace. Sure is easy to buy a couple of manufactured logs at the grocery....
But what's the deal with those composite logs that come wrapped in paper? Are they okay, or are they full of toxic chemicals?
Actually, artificial fire logs are a pretty good thing, environmentally. They burn much cleaner than real firewood. Typically, they produce 70% less particulate matter, 85% less carbon monoxide, and 50% less smoke than real wood.
In the past, fake logs were usually made from sawdust and petroleum wax. The wax produced most of the heat - the sawdust served the same purpose as a wick in a candle. But now, fake fire logs are likely to be made from natural vegetable waxes instead of petroleum wax. Vegetable waxes are extracted from plants that were recently alive and so were removing CO2 from the atmosphere during photosynthesis - as all living plants do. That compensates for any CO2 released during their burning, and makes them greenhouse-gas-neutral or "carbon neutral." So, in other words, burning fake logs made from vegetable waxes has no overall impact on climate change.
There's another new type of firelog, the Java-Log, made from recycled coffee grounds. These logs smell like coffee, produce 25% more heat than firelogs made with sawdust, and produce more brilliant flames.
One more benefit of fake logs over real logs - most fake fire logs produce less creosote to accumulate in the chimney than real logs do.
But some fake fire logs are simply 100% compressed sawdust. They have the same effect on the atmosphere and the chimney as a real log.
So if you have a choice, choose the fake logs made from vegetable waxes and sawdust, or the Java-Logs. They burn the cleanest and have minimal impact on our air and our climate.

In Peru: the plight of the indigenous Quechua
My family visited the Peruvian Andes this past summer. We loved trekking and birding in the most biodiverse country on the planet, but more than that, we loved the people of Peru. In the Andes, the majority of people we met were indigenous Quechuas. Their first language is Quechua; the women still wear distinctive traditional clothing, including the well-known fedora hats and colorful handmade garments. Some of the Quechua people we met were employed outside of their communities - as taxi drivers, or cooks at tourist lodges. But most still live the farming life; they are, in Spanish, "campesinos" or "country dwellers."
While we were in the Cordillera Blanca near the trekking mecca of Huaraz, Peru, we stayed at Llanganuco Lodge. We got to know the lodge owner Charlie Good, a transplanted British economist. He is the only Westerner in his community - his neighbors are all Quechua families who live and farm their ancestral lands. As an environmentalist and a socially-attuned resident of his community, Charlie is concerned about his neighbors' future. Apparently, the Peruvian government wants to privatize the water supply and charge Quechua farming communities in the Andes for using water from the irrigation canals that their own ancestors dug hundreds of years ago. That's a serious problem for families living on the edge of subsistence. Another accelerating problem is the influence of TV and modern technology in rural communities. With new Western aspirations, Quechua teenagers are moving to nearby towns. Their departure leads to "under-usage" of the land. Under Peruvian law, underused farm land can be reposessed by the government. So Quechua families are in danger of losing the farms that have been held by their families for a very long time.
Charlie Good, owner of Llanganuco Lodge, wrote the following piece for a publication in the nearby town of Huaraz. He gave me permission to reprint it here:
For visitors to Huaraz, the life of the Quechua Campesino may seem an idyllic one, and sure their balanced and sustainable life is enviable. Especially as they have their own plots of land, live with their families, are surrounded by their friends, and can produce all that they need.
Indeed we could do with taking a leaf out of their book in modern “society”. However the poor Andean communities of
Privatisation is a good idea I hear you say, well maybe… considering the problems this country faces with hastily retreating glaciers, but to use bureaucrats to charge the campesinos for the water they use for irrigation from the very irrigation ditches they themselves constructed….to me is highly questionable – firstly cost vs benefit issues are obvious and secondly does “Ancestral rights” not ring any alarm bells? Ancestral rights – being the very reason for the land reform act in 1968 that handed back ownership to the people of this land, which brings us to another cute one, the government legalising the sale of community land, perhaps a rumour, but a dangerous one if true. These factors and more amount to huge pressures to leave the communities. So with dwindling populations and under-usage of the communities’ lands, what happens? The government instigates old laws to seize these lands, due to under-usage, which they will now be able to sell. This all sounds like scaremongering? I just hope you are right because maintaining the knowledge of self-sustainable societies may well be essential for our survival.
In the meantime I'll be living in one of these communities promoting sustainable development and tourism, and trying to give these youngsters a reason to stay - that's my main challenge. You want to help? Great!

Number of imperiled fish almost doubles in 20 years
Forty percent of fish species in North American streams, rivers, and lakes are now in trouble. That's according to a detailed new evaluation of their conservation status by scientists from Canada, Mexico, and the U.S. Geological Survey. The report was just published by the American Fisheries Society in the journal Fisheries.
The 700 fishes now listed as imperiled represent a whopping 92% increase over the 364 listed in the previous report 20 years ago. Of those 700 imperiled fishes, 280 were listed as endangered, 190 as threatened, and 230 as vulnerable.
Said Mark Myers, director of the USGS, "Freshwater fish have continued to decline since the late 1970s, with the primary causes being habitat loss, dwindling range, and introduction of non-native species. In addition, climate change may further affect these fish."
Unfortunately for American consumers, the fish most at risk include many that are popular with sportsmen and commercial fisheries, such as salmon and trout of the Pacific Coast and western mountain regions. More than 60% of the salmon and trout species surveyed had at least one population or subspecies in trouble. Twenty-two percent of sunfishes (a family that includes popular black bass, bluegill, and rock bass) were listed.
Areas with especially high numbers of imperiled fish include the Southeast, the mid-Pacific coast, the lower Rio Grande, and basins in Mexico that do not drain to the sea.
This is the third list compiled by the American Fisheries Society's Endangered Species Committee. Of the fish on the 1989 imperiled list, only 11% have improved in conservation status. The remaining 89% are more at risk or have stayed the same.
"Fish are not the only aquatic organisms undergoing precipitous declines," said USGS researcher Noel Burkhead, chair of the AFS Endangered Species Committee and a lead author on the report. "Freshwater crayfishes, snails and mussels are exhibiting similar or even greater levels of decline and extinction."
What about that seafood dinner you have planned??
If you plan to continue eating fish, check out the Seafood Selector on the website of the Environmental Defense Fund, at http://www.edf.org/page.cfm?tagID=1521&redirect=seafood. See their "Eco-Best", "Eco-OK" and "Eco-Worst" lists of seafood, easy to understand at a glance. The webpage has lots of other information about eating fish, including fish recipes, fish substitutions, and information about pollutants such as mercury.
Our 2008 book Going Green has a section on fish called "Seafood - Here's the Catch." In this section we describe destructive mass-fishing techniques such as blast fishing, longlines, and gill nets. Sadie reports on a couple of disturbing interviews with fisheries professionals, who report that workers pee into the fish-stick vat, drop boots into the mix, etc. We were surprised too at what we learned while researching farmed fish. Most of the fungicides, dyes, antibiotics, and pesticides dumped into the cages of farmed oceanic fish actually wind up outside the cages, where they impact wild communities. And then there are the genetically modified fish..that's another distressing story. The consumption of fish is not as simple as it once was! For a thorough review of these issues, check out The End of the Line: How Overfishing is Changing the World and What We Eat by Charles Clover, or The Empty Ocean by Richard Ellis.

Audubon's annual bird count: even in the city, some species show up year after year
Article by Clay Barbour for the Charlotte Observer
Dec. 28, 2008
cbarbour@charlotteobserver.com
Taylor Piephoff and Greg Hayes came to the Renaissance Golf Course Saturday in search of birdies.
Of course, there's nothing unusual about that.
But unlike the others traipsing around the greens in the early morning fog, Piephoff and Hayes were using binoculars instead of 9-irons.
The two men were among a group of 22 area birders helping with the National Audubon Society's 109th annual Christmas Bird Count, a national effort to catalog bird populations among growing metropolitan areas.
More than 120 Carolinas bird groups are taking part in the count this year, which started Dec. 14 and runs through Jan. 5. Results are due by mid-January. The Mecklenburg Audubon has heldThe group has traditionally focused on a 15-mile circle, centered at the intersection of Woodlawn Road and South Boulevard.
Sticking to the same area allows for a controlled count that can be used to give researchers a better idea of the health of different species.
“We contribute to a data set that is used nationally and internationally to track birds,” said Ken Kneidel, an experienced birder in charge of Charlotte's count this year. “Without volunteers like we have, I don't know how this kind of research would ever get done.”
Kneidel said the Queen City's bird population has remained fairly steady since the mid 1970s, in part because of the city's protection of its tree canopy.
The chapter recorded 93 different species of birds last year, a little shy of the record of 96 set in 1983.
Birders have noticed trends in recent years. Some species have thrived as the city has grown. Others have diminished.
For example, the chapter counted 21 Canada geese in 1967. Last year, they counted 687.
Meanwhile, it recorded more than 280 purple finches in 1981. Last year, they found one.
Such numbers are rough estimates at best, relying as they do on a one-day count by volunteers. But Kneidel said that observed over time, they give researchers a good idea about population changes.
Piephoff, 48, works for Mecklenburg County's natural resources department and writes a regular column on birds for the Charlotte Observer. He started birding in 1972.
Hayes, 38, works for Bank of America. He has been birding for about 10 years.
Both men say they grew up fascinated with nature – birds in particular.
“It's a fun way to connect with the world around you, the seen and unseen,” Hayes said.
Most birders develop a keen eye for spotting birds from great distances and through thick brush. But sometimes they rely on their trained ears.
With a cold fog hanging low over the course Saturday, visibility into the woods was poor. Piephoff walked to the edge of the trees and let out a bird call that mimics the sound some make when distressed.
“Shhhwt, shhhwt, shhhwt, shhhwt, shhhwt,” his voice echoed off the trees.
A few seconds later, the woods erupted into a chorus of calls, as the birds answered.
Hayes and Piephoff rang off the names of the birds they heard as easily as others list familiar songs on the radio. A mockingbird, a white-throated sparrow, a Carolina wren and a swamp sparrow all called back.
The two men mentally logged the birds and continued on.
“In a lot of ways it is like a sport,” Kneidel said. “Finding a rare bird is like hitting a three-pointer or sinking a putt. It's exciting."Keywords:: Audubon Christmas bird count annual bird census bird conservation Charlotte Mecklenburg Audubon Clay Barbour Ken Kneidel Taylor Piephoff Greg Hayes Alan Kneidel

Volunteers for Audubon's Christmas Bird Count collect valuable conseravtion data
This year I inherited the job as “compiler” for the Charlotte Christmas bird count. If you’re unaware, the Audubon Society has sponsored annual bird counts for the past 108 years. In Charlotte, we’ve had a count since 1941. My job is to see that the count runs like it has in previous years, and to collect and submit the data we collect to a national database.
I just got a phone call from a staff writer from the Charlotte Observer putting together a piece for tomorrow’s paper. He asked “why do you do this?” It might seem odd – why would 21 people spend all day trying to count all of the birds in a 15 mile wide circle? When people first hear about the count they often express confusion – how can you possibly count every bird in an area that big? How do you avoid counting the same bird twice? The truth is, we never expect to count every bird. What we try to do is get a representative sample. We know what places to focus on to see the birds we suspect are in the circle that day. We avoid overlap by forming 8 groups, each responsible for different sections of the circle.
But that’s more about “how” than “why”. I’ve got three answers to the latter question. Number one for me is the value of the records. Over 100 counts will be carried out in North Carolina alone; thousands internationally. We birders amass a monstrous invaluable data set. Over 30 acres per day have being developed in Mecklenburg County during the past several years. All this development, plus global climate change, are having a significant impact on wildlife – we know so because data sets like the Christmas bird counts show trends.
Another reason is “sport”. For me, what we do feels like a sport. I’m reluctant to admit it, but for me there’s competition. Not so much with other birders – more with myself. Just like a golfer tries to improve every round, I like to see more birds and better birds each year. I’m reluctant to admit this because the perfect effort in doing the count would be to repeat exactly what you did the previous year so the data will be reliable. It’s important to be able to conclude that if you see more birds one year compared to another it’s because a change in bird abundance and not due to fluctuating effort. But it’s hard not to try to do “better” each year, that is, find more birds and especially more rare ones. Last week, for example, while doing a different count, my group was the first to ever see a Common Raven in Mecklenburg County, NC. For me, spotting that raven was like sinking a 150 yard iron shot from the rough on a windy day. It felt great!
Thinking about the bird count as a sport led me to notice that, from the outside, traditional sports seem a little odd too. Don’t take me wrong – I’m an avid sports fan. But hitting a white ball up and down fields with clubs might seem strange to the uninitiated. Or football – 22 grown men “fighting” to get a leather ball to one end of a large field? Maybe counting birds in a 15 mile diameter circle seems strange to some, only because they’re outside looking in. From the inside, it’s sport-like. Twenty-two people working together to achieve a difficult goal that’s challenging and requires lots of skill. Most of us will identify the majority of our birds by sound, and many not by their songs. Sometimes we’ll rely just on simple “call notes” that differ only in sound quality and pitch (we’ll struggle to decide whether we’re hearing “tseeet” or “seeep”).
Reason number three (and as important as the other two) can also be appreciated by sports fans. I’m sure that many who are obsessed with traditional sports enjoy the camaraderie and the atmosphere while watching the sport as well as the action. We 22 birders are also friends; we often bird together throughout the year, and “tailgate” every month at Audubon meetings. And our “atmosphere” tomorrow will be hard to beat. Birding requires walking slowly through natural areas, looking at and listening to everything. As you do this, you become more aware of the differences between seasons, not only in terms of the birds, but also in the vegetation, weather, and sound. The differences between places also become more obvious – field versus forest margin, thicket, or deep woods. You also see that a place of little apparent value to humans can be priceless to wildlife. For example, I’ll look forward tomorrow at seeing Savannah sparrows at an abandoned development along Shopton Rd. To anyone driving by, that lot is a “wasteland” – a “strip of pavement to nowhere”. To the sparrows it’s perfect habitat for the winter – as is the Hilton Hotel in the center of downtown Charlotte for a Peregrine Falcon! We birders know that a Peregrine has been using that hotel as a winter stopover the past few years. It likes to sit on the ‘i” on the red sign high on the side of the building. The skyscrapers of downtown Charlotte offer equivalent habitat to cliffs and open areas out West, and pigeons are good prey. After I saw that falcon, the city’s never felt the same. There’s indescribable joy in seeing a beautiful animal acting according to its nature, oblivious to human activity surrounding it. I’ll see that over and over again tomorrow in many contexts.
So that’s why. For me, I’m excited because I have a big game tomorrow. The weather will be fresh and crisp, spirits will be high. I hope we score at least “80”. I can’t wait.

The 1000th bird on my life list....at Llanganuco Lodge in Peru
Eager to hit a variety of habitats while visiting
By happenstance, birding the area around the Llanganuco Lodge coincided with my approach to the 1000th bird on my life list. How lucky I was to be staring up at Mount Huascarán (highest tropical peak in the world) instead of looking out my bedroom window back home in
We missed an Andean Condor that made an appearance for Charlie while we were there, but other birds of note were Andean Lapwing, Silvery Grebe, Puna Ibis, and Puna Teal on the lake next to the lodge, Andean Goose at
I remember quoting the movie Field of Dreams when talking with Charlie, in reference to both his lodge and the nature that surrounded us – “If you build it, they will come.” Come see what nature’s built around the lodge that Charlie’s built, and you’ll enjoy a wonderful set of birds that come right to your doorstep.

Campus "Meatless Day" raises environmental awareness
Our school is considering a "meatless day" campuswide this spring, to increase awareness of the environmental damage caused by livestock around the globe. The food service that operates our school cafeteria has agreed to facilitate our meatless day. My husband Ken, a biology teacher, has written this summary for students and faculty, to explain the impact of livestock on the world environment:Eating meat is an inefficient use of our diminishing natural resources: land, water, and clean air. We could feed the human population with much less agricultural land if we ate the grains that we presently feed our livestock. For example, it takes 7 lbs of grain to produce a 1 lb weight gain in a steer. A hog needs more than 3 lbs of grain for a 1 lb weight gain. For poultry and herbivorous species of farmed fish, 2 lbs of feed is needed for a 1 lb weight gain (Brown, 2008). Stated another way, we consume fewer natural resources when we ourselves eat the plant-based foods that we feed livestock, rather than running them through animal bodies first.
A closer look at our soybean harvest, as an example, illuminates how this inefficiency makes switching to a vegetarian lifestyle a wise choice. In 2007, the world grew 222 million tons of soybeans, only 20 million of which was consumed directly as tofu, soy milk, veggie burgers, etc. Thirty-seven million tons were used in making soybean oil; the remaining 165 million tons were fed to cattle, pigs, chicken, and fish (Brown, 2008). Averaging the inefficiencies mentioned in the previous paragraph gives roughly 4 pounds of feed needed to produce 1 pounds of meat, a ratio of four to one. This means that the 165 million tons of soybeans we feed to livestock yields only 41 million tons of meat. If we replace this 41 million tons of meat in our diet with 41 million tons of soybean products (eating them directly rather than feeding them to livestock), that would make the remaining 124 million tons of soybeans we grow unnecessary. The same argument can be made for other crops we feed to livestock as well – most of the corn and oats we grow are fed to livestock rather than eaten directly by humans. As shown below, every acre of land not used for farming in the world would act in many ways to improve the health of our planet.
Right now 70% of the agricultural land on earth (and 30% of the earth’s land surface) is set aside for livestock pastures or growing food for livestock (Steinfeld et al., 2006). Every acre that we free up and return to its natural state would reduce our demand for water, expand forests and other natural habitats, and lower the volume of pesticides, herbicides, and antibiotics we release into the environment.
Since much of the feed we grow for livestock is irrigated, raising livestock consumes an enormous amount of water. Worldwide, the livestock sector accounts for 8% of water used for human activities. Raising one steer, for example, requires 1.2 million gallons of water, considering the irrigation of the steer’s feedcrops. Producing one pound of ground beef requires 5214 gallons, while one pound of either lettuce, potatoes, tomatoes, or wheat, requires only 23 to 25 gallons (Robbins and Ornish, 2001)
As an example of how the livestock industry impacts habitat destruction and deforestation, consider our loss of tropical rain forests. Thus far, roughly 20% of the Amazon rainforest has been cleared either for cattle ranching or soybean farming (soybeans primarily for livestock feed). Tropical rain forests have been estimated to contain from one-third to one-half of the world’s species. As these forests are cut, our global biodiversity will plummet.
In contrast, livestock are so numerous that they account already for 20% of the total mass of all land animals on earth. They preempt 30% of the earth’s land surface from occupation by wildlife. Besides driving deforestation, the livestock industry is one of the main factors behind land degradation, overfishing, sedimentation of coastal areas, and facilitation of invasions by alien species (Steinfeld et al., 2006).
What about the atmosphere and climate change? The livestock sector is responsible for 18% of global greenhouse-gas production. It has a larger impact on climate change than transportation, making eating less meat just as important, if not more so, than buying a hybrid vehicle, switching to fluorescent lights, or buying Energy Star appliances, etc. The livestock industry accounts for 9% of our CO2 emissions, 37% of methane, and 65% of nitrous oxide (all are greenhouse gases). The latter two are more important than many people realize. Methane has 23 times the global warming potential as CO2, molecule per molecule, while nitrous oxide has 296 times.
Livestock is also responsible for 64% of our ammonia production, which contributes significantly to acid rain and acidification of ecosystems (Steinfeld et al., 2006). The loss of trees due to acid rain reduces the earth's ability to absorb CO2 through photosynthesis, and impacts climate directly by altering weather patterns. A tropical forest cools the air around it while cropland heats it; forest loss affects climate around the world.
The livestock industry is also a major water polluter. Livestock produce 291 billion pounds of manure per year in the US – six times the amount of human sewage (1 steer produces 50-60 lbs of manure a day, one dairy cow 120 lbs (Robbins and Ornish, 2001)). None of this waste is sent to a treatment plant; instead it’s sprayed over cropland or housed in lagoons that leak. This waste matter ultimately works its way into our water supply. Nitrate concentrations under hog-waste lagoons have been measured at 10 times safe levels set by the EPA (Kneidel and Kneidel, 2005).
Our environment is also becoming polluted with antibiotics as a result of their use in the livestock industry. Every year, approximately 25 million pounds of antibiotics and related drugs are administered to animals in sub-therapeutic purposes, primarily for the purpose of boosting growth rates. This is more than eight times the amount used to treat disease in humans (Union of Concerned Scientists, 2003). Livestock typically shed in their feces up to 90% of the antibiotics fed to them, leading to antibiotic resistance in soil bacteria. Research has shown that using manure to fertilize soils also leads to the incorporation of unaltered antibiotics into plant matter, and therefore into our diet (Kumar et al., 2005).
Americans lead the way by far in per capita meat consumption. The average American eats 246 pounds of meat per year (74.4 billion pounds for 300 million people); other industrialized nations eat an average of 176 pounds per person per year; 66 pounds pp per year in developing nations (Nierenberg, 2005). Unfortunately the amount of meat being eaten across the globe is increasing. World meat consumption has more than doubled between 1950 and 2005. Consumption of milk and eggs has also risen. In every country where incomes have risen, meat consumption has too (Brown, 2008).
With our population projected to increase from 6.6 billion to 9.2 billion by 2050, it’s clear that we just can’t go on eating as much meat as we’re eating today. Change is easy. One day at a time. We can all start with one meatless day per week.

You'll save the energy you would normally expend shopping and every item not purchased means less energy going into the production, packaging and shipping of that item.
2. Buy rechargeable batteries!
Over 40% of battery sales are made during the holidays according to the California Energy Commission. Using and reusing rechargeable batteries will reduce your trips to the store to buy batteries, and reduce the energy that goes into mining the metals, manufacturing the batteries, and shipping.
3. Buy local gifts!
Giving movie tickets, restaurant certificates, a babysitting promise, etc., uses fewer resources and less transportation. Other local items could include locally produced food, crafts, and jewelry.
4. Recycle that wrapping paper!
Buy recycled gift-wraps, which use 60% less energy to produce than virgin paper (and generate 95% less air pollution) according to Earth911.com. Or get creative and make your own gift wrap using comic pages, ribbons and other items that you have on hand. And after the holiday, reuse or recycle the paper, gift bags and ribbons on the gifts you receive.
5. Use LED holiday lights!
LED holiday lights are not widely available and reduce energy consumption by 80-90%. Turn your decorative lights off overnight. 6:00-10:00 PM are the prime visibility hours.
6. Eat fewer animal products for your holiday meal!
The meal doesn't have to be centered around turkey or ham. Make it a potluck, with a couple of people bringing veggie or bean casseroles. Or feature a pumpkin or broccoli sour as your entree. With a salad, savory bread, a scrumptious desert, who needs flesh? According to the United Nations document "Livestock's Long Shadow", livestock production generates more greenhouse gases than does transportation.
7. Keep the oven door shut!
Resist the temptation to open the oven door and check the casserole - even opening it once can reduce the temperature by 25 degrees. Consider baking several dishes at once, and use the right size for your stovetop burner, which can reduce energy waste by as much as 40%.
8. Turn the heat down when crowds are in the house!
With more warm bodies, you can set the thermostat lower and stay just as comfortable. The EPA recommends no higher than 68 degrees for the most economical and comfortable thermostat setting.
9. Stay home for the holidays!
A round trip flight from New York to Los Angeles produces 1, 436 lbs of CO2 according to Terra Pass. If you can stay home, you'll save energy. If not, buy carbon credits from Terra Pass or a similar company, to offset the greenhouse gases spewed out by your jet. Click here to read our review of the highest-rated companies that sell carbon offsets for plane travel.
10. Make your own holiday cards from recycled paper or send E-cards instead!

Did your shopping list kill a songbird?
Though a consumer may not be able to tell the difference, a striking red and blue Thomas the Tank Engine made in Wisconsin is not the same as one manufactured in China — the paint on the Chinese twin may contain dangerous levels of lead. In the same way, a plump red tomato from Florida is often not the same as one grown in Mexico. The imported fruits and vegetables found in our shopping carts in winter and early spring are grown with types and amounts of pesticides that would often be illegal in the United States.
In this case, the victims are North American songbirds. Bobolinks, called skunk blackbirds in some places, were once a common sight in the Eastern United States. In mating season, the male in his handsome tuxedo-like suit sings deliriously as he whirrs madly over the hayfields. Bobolink numbers have plummeted almost 50 percent in the last four decades, according to the North American Breeding Bird Survey.
The birds are being poisoned on their wintering grounds by highly toxic pesticides. Rosalind Renfrew, a biologist at the Vermont Center for Ecostudies, captured bobolinks feeding in rice fields in Bolivia and took samples of their blood to test for pesticide exposure. She found that about half of the birds had drastically reduced levels of cholinesterase, an enzyme that affects brain and nerve cells — a sign of exposure to toxic chemicals.
Since the 1980s, pesticide use has increased fivefold in Latin America as countries have expanded their production of nontraditional crops to fuel the demand for fresh produce during winter in North America and Europe. Rice farmers in the region use monocrotophos, methamidophos and carbofuran, all agricultural chemicals that are rated Class I toxins by the World Health Organization, are highly toxic to birds, and are either restricted or banned in the United States. In countries like Guatemala, Honduras and Ecuador, researchers have found that farmers spray their crops heavily and repeatedly with a chemical cocktail of dangerous pesticides.
In the mid-1990s, American biologists used satellite tracking to follow Swainson’s hawks to their wintering grounds in Argentina, where thousands of them were found dead from monocrotophos poisoning. Migratory songbirds like bobolinks, barn swallows and Eastern kingbirds are suffering mysterious population declines, and pesticides may well be to blame. A single application of a highly toxic pesticide to a field can kill seven to 25 songbirds per acre. About half the birds that researchers capture after such spraying are found to suffer from severely depressed neurological function.
Migratory birds, modern-day canaries in the coal mine, reveal an environmental problem hidden to consumers. Testing by the United States Food and Drug Administration shows that fruits and vegetables imported from Latin America are three times as likely to violate Environmental Protection Agency standards for pesticide residues as the same foods grown in the United States. Some but not all pesticide residues can be removed by washing or peeling produce, but tests by the Centers for Disease Control show that most Americans carry traces of pesticides in their blood. American consumers can discourage this poisoning by avoiding foods that are bad for the environment, bad for farmers in Latin America and, in the worst cases, bad for their own families.
What should you put on your bird-friendly grocery list? Organic coffee, for one thing. Most mass-produced coffee is grown in open fields heavily treated with fertilizers, herbicides, fungicides and insecticides. In contrast, traditional small coffee farmers grow their beans under a canopy of tropical trees, which provide shade and essential nitrogen, and fertilize their soil naturally with leaf litter. Their organic, fair-trade coffee is now available in many coffee shops and supermarkets, and it is recommended by the Audubon Society, the American Bird Conservancy and the Smithsonian Migratory Bird Center.
Organic bananas should also be on your list. Bananas are typically grown with one of the highest pesticide loads of any tropical crop. Although bananas present little risk of pesticide ingestion to the consumer, the environment where they are grown is heavily contaminated.
When it comes to nontraditional Latin American crops like melons, green beans, tomatoes, bell peppers and strawberries, it can be difficult to find any that are organically grown. We should buy these foods only if they are not imported from Latin America.
Now that spring is here, we take it for granted that the birds’ cheerful songs will fill the air when our apple trees blossom. But each year, as we continue to demand out-of-season fruits and vegetables, we ensure that fewer and fewer songbirds will return.

Devon discovers illegal scam, rushes to protect forest
My family met Devon Graham in June of 2008 - he's a tropical biologist and president of Project Amazonas, a conservation nonprofit in the Peruvian Amazon. See our previous post about our visit to Iquitos and to two Project Amazonas biological stations on tributaries of the Amazon River. We loved Iquitos - part of its charm is being the biggest city in the world inaccessible by road. But Devon told me recently that this distinction is changing - a new road is underway that will link Iquitos with the Napo River port of Mazan. A road through rainforest brings bad news for rainforest wildlife. The road provides, for commercial interests, access to areas that were previously too remote to be profitable. Loggers, slash-and-burn ranchers, and illegal wildlife traders move in. A new road unleashes an avalanche of forest exploitation and development.
Devon points out that the Amazon is in many ways a frontier. The area lacks adequate law enforcement, so illegal exploitation is commonplace. See our post on the market in Iquitos, where threatened wildlife species are sold for the same price as a couple of mangos. The following is a story of Devon's discovery of attempted theft of rainforest trees along the new road-under-construction. It's a systematic exploitation by logging companies that works because local communities lack the infrastructure to stop it. But this time, maybe it won't work, if Devon has his way.
Here is the story, in Devon's words:
"I’m really starting to regret having decided to check out the new road. What was going to be a quick jaunt has turned into aching thighs, sunburned face, tense arms, hand spasms from gripping too tightly, and a lot of déjà vu of the time I put 10,000 km on a 75 HP Suzuki motorcycle in 5 months – most of it off-road.
But that was in the Peace Corps 20+ years ago, and my body isn’t as tolerant of such punishment any more. The new road between
Some sections are 50 feet wide and relatively smooth (apart from grader-tracks), but other, longer sections are definitely of “off-road” quality: deeply rutted, muddy, dusty, blocked by heavy machinery, covered with grasses and brush, composed of curving 20-percent grades, and crossed by drainage channels – sometimes seemingly all at once. At one point the road crosses directly across a soccer field in front of a school, and we zoom though the goal posts. “!Gol!” exclaims Luis, my driver; “doble-gol” I respond, and he chuckles as we bounce along. I wonder what happens when a game is actually in progress. Later on we lose Fernando Rios, the in-country Project Amazonas manager, and his driver Ricardo for a while. When they catch up they explain that they were held up by an ornery cow. “¿La vacita negra?” (“The little black cow?”) Luis asks. They nod. We’d both noticed it staring madly at us as we went past where the road crossed a pasture. I guess a suffering gringo on the back of a roaring motorcycle pushed its bovine brain over the edge. It couldn’t take any more, and I’m getting to the same point. The pasture-lands and farms grade into tall forest on both sides as the ribbon of dirt and mud slides by beneath the wheels, and fourteen kilometers down the road I spot a sign on the side of the road – the first sign we’ve seen on this newest of roads. I breathe a sigh of relief, tell Luis to stop, and stiffly and ungracefully get off the back of the motorcycle. We have arrived.
Fernando and I are on a mission to check out the road access to the newest of the Project Amazonas field sites and forest reserves in
Fernando Rios in forest interior at the Santa Cruz site
The sign we’ve reached was installed by Fernando in July at the eastward extension of our new lands. He has another sign ready to install at the western extension border with the road once the pending land sale is completed. I’m so glad to be off the motorcycle that we walk the entire 2 km extension of road frontage of the property. Approximately mid-way along, there is a bend of the road with a nice flat area lacking large trees. Centrally, it drops off gently to the valley bottom, and more steeply on either side to a pair of small creeks. Fernando and I agree that it would be an ideal location for a caretaker’s house and educational center. Patrolling the road frontage would be easy from such a centrally located site (we’re envisioning a regular dirt-bike for the caretaker to use), and a trail network could be started from the same location without having to navigate any immediate steep slopes. As we walk along the road, we notice numerous shungos, (below) the hard, rot-resistant heartwood of long-dead trees of various species bulldozed to the side.
A "shungo" or long-dead tree good for construction instead of living trees
These will serve as excellent material both for fencing the road frontage, as well as for construction. There won’t be any need to cut large living trees for those purposes. Fernando is enthused by the number of large tornillo trees (right and next page) – these are highly valued for boat building purposes and for certain types of construction that require a very dense wood that can resist the rot that results from frequent wetting and drying. I’m more enthused by the number of birds that I can hear in the forest or that are flying across the road. Unfortunately my binoculars are waiting for me at the Madre Selva Biological Station – several hours downriver from
Before long we reach the border of the lands that Project Amazonas has title to. A narrow cleared line in the understory marks where one parcel of land begins and the other ends. These border lines are the standard means of marking property boundaries in the Amazon. Curiously, however, this border line appears to be freshly cleared, and at the road edge is a wooden post sporting a trio of blue plastic “A’s”.
The mysterious blue "A's"
We puzzle over why the land owner would bother to put in a post and clear the border right before a sale is finalized. Walking down the road to the other edge of the to-be-acquired-parcel, we spot another wooden post with the enigmatic blue “A’s”. Fernando tries to call the land-owner, but cell-phone reception is spotty in this hilly area, and so we continue to wonder. We decide to take the motorcycles a bit further onward to where the Santa Cruz forest reserve lands end and another community’s lands begin. The delineation couldn’t be much more obvious. On one side of the cleared border strip is tall forest, the other side is covered by bananas and plantains, with the odd remnant tree sticking up as if to emphasize the lack of forest cover. The air itself feels hotter. We hop back on the motorcycles and head back toward Mazan – we could have continued on to
Once in Mazan, there is good cell coverage again. Fernando makes a series of calls, and eventually we’re in touch with the landowner. The mystery of the triple blue “A’s” begins to unfold. The landowner is surprised, and is not responsible for them. The community of
This time, however, the plot has been caught early before any damage has been done. I instruct Fernando to let the
My butt may be sore, my arms and face burned, but I’m burning hottest inside! There’s forest to be saved and work to do."

Project Amazonas needs to raise $175/month to fund a caretaker position at the new forest reserve. The caretaker will assist students and researchers, maintain trails and buildings, and prevent logging and other activities that might damage the mature rainforest at this site. To make a tax-deductible donation (in the USA), please contact Project Amazonas president Devon Graham (mionectes@aol.com) or mail a check to:
Postscripts by Devon:
On 6 August 2008, thanks to a lot of footwork by Fernando Rios, we finalized the purchase of the adjacent 24 ha (60 acres) from the adjacent landowner, and now have the official title to Lot 77, along with the transfer of title and all other legal papers. We need about $750 to finalize the transfer of title, official survey papers, and notarization fees for Lots 73, 74, 75 and 76 which, when done will give us the single contiguous block of land of 104 ha (260 acres).
