The document discusses the evolution of environmentalism movements from the 1960s to present. It describes the classic environmentalism of the 1960s-1970s which focused on "back to nature".

The document then outlines the rise of the Bright Green environmentalism of the early 2000s which promoted science, technology, responsible business and sustainable society as the solution. It provides two quotes from 2006 and 2007 discussing how technology is leading environmentalism out of anti-business stances and how a dot-green future of consuming responsibly can help planetary survival.
