Sobering yet hopeful

Great review of Malthus Enigma by Dan Hoornweg:

"This book provides an excellent summary of where we are as our collective impacts have now crossed seven planetary boundaries. How did human nature, technologies and economies lead us to this quandary (the 'Malthus Enigma')?"

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.
