Switch to plant-based diets saves land, reduces pollution

Most of the grain grown in the US heartland go to feed livestock. That same land could be used to grow food directly for humans–and since studies consistently show that plant-based diets require less land than meat- and dairy- based diets, some of the land could revert back to its natural habitat, giving native wildlife currrently displaced by feedcrops a chance to rebound.

Accordingly, with a transition away from meat and dairy, less fertilizer would be required and there would be less manure washing into the Mississippi River and the Gulf of Mexico.
