Lester Brown is one of the most well known environmental analysts in the world. Founder of the Worldwatch Institute and the Earth Policy Institue, Brown has been described by the Washington Post as ” one of the world’s most influential thinkers.” Brown has written a number of best selling books, including last year’s World on the Edge: How to Prevent Environmental and Economic Collapse. That book is the subject of the lecture he gave at the Cambridge Forum and which you can watch below. It’s worth a listen.
