If you've ever taken a drive through the rural Midwest in the United States, you've likely had the pleasure of seeing acre upon acre of rolling farmlands planted with primarily corn and soybeans. On the surface it's a calming sight, evoking images of a simpler, more wholesome time -- but unfortunately if you dig beneath the surface the image is much darker, because most of these crops are far different from the ones our ancestors first planted generations ago.

Today, upwards of 85 percent of U.S. corn crops contain a special gene added that allows them to produce an insecticide. This way, when bugs attempt to eat the corn they're killed right away (specifically their stomach is split open) because the plant contains an invisible, built-in pesticide shield. The problem is, of course, that when you eat this corn you eat the built-in pesticide as well, and as you might suspect this is proving problematic for human health and the environment.
