Paul Hawken

When cattle ranchers clear rain forests to raise beef to sell to fast-food chains that make hamburgers to sell to Americans, who have the highest rate of heart disease in the world (and spend the most money per GNP on health care), we can say easily that business is no longer developing the world. We have become its predator.

We assume that everything's becoming more efficient, and in an immediate sense that's true; our lives are better in many ways. But that improvement has been gained through a massively inefficient use of natural resources.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
