We're supposed to show people how the world is, to give them the tools they need to make good decisions as citizens or consumers. Depending on what your values are the environment, your health, animal welfare the answers are going to be different for every person.
The green thumb is equable in the face of nature's uncertainties; he moves among her mysteries without feeling the need for control or explanations or once-and-for-all solutions.

Eating is an agricultural act,' as Wendell Berry famously said. It is also an ecological act, and a political act, too. Though much has been done to obscure this simple fact, how and what we eat determines to a great extent the use we make of the world - and what is to become of it.
