ABSTRACT
The authors of these two books, Mark Lynas and James Gustave Speth, share a passion for safeguarding the future of this Earth; and both identify reasons why this future is threatened. They are both campaigners and these books set out, in different ways, to convince the reader of their key message: that the signs of global warming are now evident around the world (Lynas) and that the Earth’s future can be sustained through citizens’ actions (Speth).
