- Jeremy Grantham

“ On the environment and climate change, I suspect that future generations will think there was too much timidity, too much fear of upsetting business.

“ Environmental concern is a little like dieting or paying off credit-card debt - an episodically terrific idea that burns brightly and then seems to fade when we realize there's a reason we need to diet or pay down our debt.
