Eat more kale2. Better beach vacations.

As the Stockholm International Water Institute points out, it’s not always the animals but what they eat that causes major global crises. And when it comes to animal feed, pesticide- and fertilizer-heavy corn reigns supreme, making up 90 percent of what pigs, chickens, and cows eat. Growing that corn requires heavy doses of nitrogen-based fertilizers, which farmers often overuse. The excess gets washed into the Mississippi River and then dumped into the Gulf of Mexico, creating large algae blooms that kill animals. Public health officials often need to close beaches when nitrogen pollution is high—and that’s a real buzz kill for any vacationer.
