Excellent Review by Ugo Bardi (Club of Rome) "Kennedy's book doesn't just examine Malthus; it is a comprehensive critical review of a subject that's essential for all students of the environment to properly understand: the limits of Earth's environment and how humankind should deal with them."

Pretty awesome to see astronauts react to photos they’ve taken. They’re so pumped! I can wait to see what they’ve captured! #artemis #nasa

Hopefully the Earth seen from #Artemis II will inspire a new 'Age of Ecology' (just like Apollo 8). This picture was from NASA's live feed.

Launch of Artemis II reminds us of the Apollo 8 mission to the Moon and the famous Earthrise picture (the opening story in Malthus Enigma)

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')?"

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.
