The author of the international bestseller The Sixth Extinction returns to humanity's transformative impact on the environment, now asking: after doing so much damage, can we change nature, this time to save it?

Meet the biologists trying to save the world's rarest fish; the engineers who are turning carbon emissions to stone; the researchers trying to develop a 'super coral'; and the physicists contemplating shooting tiny diamonds into the stratosphere to cool the earth.
