Three profound transformations are under way on Earth: climate change, urbanization and biotechnology. Climate change is finally pushing us towards recognizing the need to manage the planet as a whole. With half the world's population now living in cities - a figure that is rising fast - urbanization is altering profoundly humanity's land impact and wealth. And biotechnology is becoming the world's leading engineering tool.
In response to these seismic changes - and the challenges they create - Brand argues that the environmental movement must reverse some of its long-held opinions, and embrace tools and disciplines that it has traditinally distrusted - such as science and engineering - in order to forestall the catacysmic deteriouration of the earth's resouces.
