Some foods, like it or not, are best avoided completely, no matter how delicious they may taste. Conventional Coffee From an environmental standpoint, it’s crucial to buy shade-grown, organic coffee. (Fair trade is also important for the growers.) Coffee is meant to grow in the shade, but many farmers now grow it in full sunlight, with a heavy dependence on pesticides, herbicides, fungicides, and fertilizers. They also chop down rainforests, destroying bird habitats. Look for the green frog stamp from the Rainforest Alliance when purchasing coffee. Factory-farmed Beef “Cheap burgers are environmental assassins,” says Logan Strenchock, Central European University’s sustainability officer. Forests are clear-cut to grow the GMO corn and soy used to feed cows. Those crops have awful pesticide runoff that contaminate waterways, not to mention the waste generated by keeping large numbers of cows in CAFOs (concentrated animal feeding operation). Even grass-fed beef “depletes native biodiversity, increases invasive exotics, diverts water, fouls streams, and bares the soil,” according to Mary O’Brien, director of the Utah Forests Program. Then the fresh meat has to be kept cool till it’s used, requiring vast amounts of energy. Palm Oil Palm oil is used in half of all packaged foods sold in the U.S., particularly cookies, crackers, and soups. Pam oil is the largest cause of rainforest destruction, resulting in huge swaths of Indonesian and Malaysian rainforests being bulldozed in order to plant palm oil trees. “Eight million acres have been cleared and burned already, and the orangutan is on its way to extinction,” says Christy Wilhelmi, author of Gardening for Geeks. The solution? Ditch those packaged foods, start cooking from scratch, and always, always read labels. Bluefin Tuna Bluefin is a popular choice at high-end sushi restaurants, but their numbers in the oceans are dropping fast. Because they live so long, Bluefin are unable to stand up to overfishing. They’re also high in mercury. The Sierra Club quotes food critic Jonathan Gold, saying, “People need to stop eating Bluefin tuna, period... The numbers of these magnificent fish are dropping fast. If we don’t stop eating them now, we’ll stop in a few years anyway because there won’t be any more.” Genetically Modified Corn GMO corn “destroys habitats, depletes soils, breaks nutrient cycles, pollutes air and water, contaminates native maize varieties, and on and on,” according to Douglas Fox, professor of sustainable agriculture at Unity College. It kills bees, reduces biodiversity, drives heirloom crops to extinction, and requires excessive processing to transform it into high fructose corn syrup, another ingredient found in processed foods (which should be avoided anyways because they contain palm oil). No doubt there are many other foods that should be added to this environmental blacklist, but banishing these five from one’s diet is a good place to start.
