Jonathan Foley ：另一个棘手的事实

Modern agriculture shapes nearly 40 percent of the Earth’s land and uses most of its fresh water, making it the leading cause of climate change, biodiversity loss, and environmental destruction. Rivers like the Colorado can dry up completely to irrigate distant crops, while the Aral Sea became a toxic desert after decades of water diversion for farming. As global population and meat consumption soar, doubling food output without wrecking the planet will require bold new thinking and cooperation. Only by blending high-yield farming, conservation, and smarter diets can humanity hope to meet this immense challenge.
