Environmental history was . . . born out of a moral purpose, with strong political commitments behind it, but also became, as it matured, a scholarly enterprise that had neither any simple, nor any single, moral or political agenda to promote. Its principal goal became one of deepening our understanding of how humans have been affected by their natural environment through time and, conversely, how they have affected that environment and with what results.

Human domination over nature is quite simply an illusion, a passing dream by a naive species. It is an illusion that has cost us much, ensnared us in our own designs, given us a few boasts to make about our courage and genius, but all the same it is an illusion.

We may be entering a new phase of history, a time when we begin to rediscover . . . the traditional teaching that power must entail restraint and responsibility, the ancient awareness that we are interdependent with all of nature and that our sense of community must take in the whole of creation.

Rain is a blessing when it falls gently on parched fields, turning the earth green, causing the birds to sing.

There is little history in the study of nature, and there is little nature in the study of history. I want to show how we can remedy that cultural lag by developing a new perspective on the historian's enterprise, one that will make us Darwinians at last.
