The green movement used to protect the earth from mankind; now they need to protect mankind from the earth. In

Whole Earth Discipline, Stewart Brand argues that in order to do this, they urgently need to abandon much conventional environmental wisdom, and embrace new science and engineering.

Combining rigorous thinking and blazing advocacy, this is a powerful and persuasive challenge, and a wake-up call to everyone who cares about the future of our Earth.
