How fast should we leave fossil fuels behind, and must growth itself slow to save the planet? It is the question that sets economists against ecologists. Wangari Maathai, who planted forests against poverty and drought, sits at the table with Elinor Ostrom, Margaret Thatcher and John Maynard Keynes. Where each of them lands is for the debates to tell.

How fast can societies move off fossil fuels without breaking the economy?
Must we slow growth to save the climate, or can we grow our way out?
Do we restore nature by stepping back, or by managing it?
