'What Should Americans Eat?' Michael Pollan and the Politics of Food

I'm Steve Ember.

VOICE TWO:

Mister Pollan shows other ways that the modern farming of corn has harmed the natural environment. In the past, farmers grew many kinds of products. Today, most farmers use all of their land to grow only one crop, such as corn. This has done great harm to the biodiversity of farmlands. The writer shows that industrial farming is unsustainable because it destroys the resources it depends on.
