Supporters see the biotechnology revolution in agriculture as a Promethean step forward, whereas critics see it as the start down a slope to futuristic disaster.

Free markets alone will not suffice to realize the new technology's promise while avoiding its pitfalls.
After thousands of years of agriculture and logging, the world is losing its trees at a rate faster than it can afford. Fortunately, a Great Restoration of the forests is already under way. More-efficient farmers and foresters are helping matters, as are the growth of recycling and other advances. But more work remains to be done.
