How about Chapter 1 on the Gift of Apollo? This recaptures the spirit of the 1960s environmental revolution and the promise of the ‘Age of Ecology.’

Just published my second book this year: www.e-elgar.com/shop/gbp/adv.... Unlike 'Malthus Enigma', which is for a general reader, my new book is more technical. It draws upon 30 years experience advising governments and international institutions on climate and sustainability solutions.

Thanks Heather. I totally agree re. methane. Don't read too much into my N&S quote. I reject their approach in the final chapter, but find their dark yet hopeful quote fitting for wrapping up the Enigma.
