Since the Cold War, American and Russian leaders have been wary of a nuclear war. Even a limited nuclear exchange between nations would cause catastrophic destruction for the environment and society.

But what are the likely effects on global food production during a nuclear winter? Two researchers at Penn State University recently found that small segments of humanity might survive a nuclear apocalypse, in part thanks to some wild, edible plants and insects in tropical places.
