Despite a tenfold increase in the use of pesticides between 1947 and 1974 (in the US), crop losses due to pests have...remained at an estimated 33%. Losses due to insects alone have nearly doubled, ...from 7% in the 1942-1951 period to about 13% in 1974.

Hunger is a people-made phenomenon, so the central issue is power: the power of those who make the decisions about what is grown and who, or what, it's grown for.

What we do in the book my daughter Anna and I wrote, Hope's Edge, is to give people a glimpse of food as a source of nourishment, health, and community, rather than a threat. That means reconnecting with food as it comes from the Earth and with those who produce food.

I also believe that it's almost impossible for people to change alone. We need to join with others who will push us in our thinking and challenge us to do things we didn't believe ourselves capable of.

I understand, of course, that grain-fed meat is not the cause of the world hunger problem - and eating some of it doesn't directly take food out of the mouths of starving people - but it is, to me, a symbol and a symptom of the basic irrationality of a food system that's divorced from human needs. Therefore, using less meat can be an important way to take responsibility. Making conscious choices about what we eat, based on what the earth can sustain and what our bodies need, can help remind us that our whole society must begin to balance sustainable production with human need.

We can't see ahead of time what actions are going to be the ones that move history in dramatic ways.

On the one hand, our social nature is our greatest beauty - it means that we have natural empathy and sympathy. But our social nature also means that we may let ourselves be controlled by the judgments of others, precisely because we care so much about our status in community.
