Do you know what you're eating? Do you know what you're feeding your children? Chances are, the last time you visited the grocery store, you unwittingly purchased foodstuffs that have been genetically altered. That means you've become part of a grand, yet alarming experiment on food and humans, being carried out on a global scale by powerful biotech companies. And no one, including the scientists and the governments who are giving them the go-ahead, knows the long-term effects of genetically modified foods. In Unnatural Harvest , Ingeborg Boyens presents the startling implications of a new technology that is quietly revolutionizing the production of food -- our most basic component of life -- exposing the serious consequences this science poses for the biodiversity of our planet, for animal welfare, and for the health of ourselves and our children.
