Federal agencies and state governments are spending millions on anaerobic digesters to wring renewable energy from animal poop. But critics say “cow power” from factory farms is neither clean nor green.
For Hakai Magazine, I interviewed Danielle Bissett about her work restoring oysters to the New York Harbor with the Billion Oyster Project.
Imagine for a moment, a possible future, some years ahead: Across the plains, acres that were once plowed up and planted to corn or wheat go back to native grass. Marginal, flood-prone land is left to return to wetlands, improving water quality downstream. Farmers diversify their operations in order to effectively manage risk in a changing climate. Monocropping is a thing of the past.
Or this scenario, not so long from now: Growers adopt practices like no-till and cover cropping, which helps lower their inputs—the money spent on fertilizer, pesticides, seed, and anything else they need to get a crop in the ground. They turn a profit with ease. They may even switch to cheaper, non-GMO seeds and see profit margins swell.
In this future tableau, cattle are turned out to pasture on land that was once intensively farmed. Land managers plant low-cost grasses and other silage, and graze livestock on a portion of the land while the remaining acres are allowed to rest and regenerate. There’s always something growing in the soil, anchoring nitrogen, helping retain rainwater, and sequestering carbon.
This is what American agriculture could one day look like, according to farmers, environmentalists, and economists. But first we’d have to get rid of federally subsidized crop insurance.
Crop insurance works too well for farmers who farm without regard for long-term soil health, and not well enough for the few who do. A new task force wants to change that.
This spring, historic flooding across the Great Plains and Upper Midwest engulfed millions of acres of cropland. The fields were so inundated, many farmers couldn’t farm; the pace of corn planting was the slowest in 40 years. With one eye on the sodden ground and the other on the calendar, farmers were faced with a terrible choice: risk planting late in the season, a move that could cost them a yield and income in the fall, or rely on crop insurance, which provides some coverage when extreme weather prevents planting.

Habitat loss is a major factor in the decline of insect populations around the world, a trend that one group of researchers has warned could bring about the “catastrophic collapse of nature’s ecosystems.” For instance, the monarch butterfly population has fallen 99.4 percent since the 1980s—a precipitous decline that has wildlife conservationists calling for them to be listed as an official endangered species. While the monarch may be the charismatic megafauna of the insect world, other, less photogenic species are believed to be facing the same fate.
That’s where you come in: Even in small amounts, native grasses and wildflowers can provide essential shelter and food for a wide variety of wildlife—especially insects. No matter how much outdoor space you have to work with—whether a big backyard or a teensy window box—there are flowers, shrubs and grasses that you can grow to support a wide range of insect wildlife.
