For a wee side-project I'm doing, I'd be grateful for suggestions of your favourite breakthrough green thinkers - people who have really made a difference in the sustainability field like Rachel Carson (of Silent Spring fame) rather than communicators/campaigners like Al Gore and George Monbiot.
For example, the people who I rate are Amory Lovins (RMI), McDonough & Braungart (MBDC), Jaime Lerner (Curitiba), Prof Tim Jackson (Surrey Uni), Janine 'Biomimicry' Benyus and Bob Frosch (ISIE). Other candidates could be Nicholas Stern, James Lovelock (gaia) and David Pearce (Blueprint for a Green Economy).
Thanks in anticipation of your wisdom!
, Benyus extends the natural metaphor to larger industrial systems which leads us to our old friend
