Avoiding meat and dairy products is the single biggest way to reduce your environmental impact on the planet, according to the scientists behind the most comprehensive analysis to date of the damage farming does to the planet. The new research shows that without meat and dairy consumption, global farmland use could be reduced by more than 75% – an area equivalent to the US, China, European Union and Australia combined – and still feed the world. Loss of wild areas to agriculture is the leading cause of the current mass extinction of wildlife. The new analysis shows that while meat and dairy provide just 18% of calories and 37% of protein, it uses the vast majority – 83% – of farmland and produces 60% of agriculture’s greenhouse gas emissions. Other recent research shows 86% of all land mammals are now livestock or humans. The scientists also found that even the very lowest impact meat and dairy products still cause much more environmental harm than the least sustainable vegetable and cereal growing.

Heraud researched the scourges of agriculture: hypoxic dead zones in the Gulf of Mexico and Baltic Sea, the colony collapse of bees, soil degradation, and human health problems from allergies to cancers. “Everything tied back to the blind, rampant, broadcast spraying of chemicals,” Heraud says. He and Redden figured they could teach machines to differentiate between crops and weeds, then eliminate the weeds mechanically or with targeted doses of nontoxic substances. The two first considered hot foam, laser beams, electric currents, and boiling water. They’d market the robot to organic farmers, who spend heavily on chemical-free weeding methods including mechanical tillage, which can be both fuel-intensive and damaging to soil. After months of research, they faced a disappointing truth: There was no way around herbicides. “Turns out zapping weeds with electricity or hot liquid requires far more time and energy than chemicals—and it isn’t guaranteed to work,” Heraud says. Those methods might eliminate the visible part of a weed, but not the root. And pulling weeds with mechanical pincers is a far more time-intensive task for a robot than delivering microsquirts of poison. Their challenge became applying the chemicals with precision.

Earlier in 2007 the Soil Association organized an amazing conference, “One Planet Agriculture: Preparing for a Post Peak-Oil Food and Farming Future.” Many talks from this conference are recorded and transcribed here, and I daresay if these are issues with which you are unfamiliar (or issues on which you are worse than unfamiliar because you have settled for mainstream mediated vacuities), devoting a lazy holiday afternoon to these marvelous talks might be a positively life-changing experience for you.
