About 40 percent of the Earth’s surface is grassland, mostly used for grazing animals. They aren’t only cattle — sheep, goats, yaks, camels, llamas and alpacas, and the people who tend to them all depend on grasslands. Grasslands are one of the most effective carbon sinks — the deep roots of grasses can store as much carbon as trees, and that carbon remains even when the grasses are grazed or burned off. Grasslands are rapidly being depleted by conversion to more intensive agriculture. But climate scientists now see their enormous value in the fight against global warming.
