Welcome to the Anthropocene era, when human impacts begin to overwhelm those of other species. The implication, as long-term environmentalist Steward Brand put it, is that "Humanity is now stuck with a planet stewardship role." Then provocatively, he argued, "We are as gods and have to get good at it."

So where would you look for people - and industries - that are good at thinking through what it would mean to be a god responsible for looking after Planet Earth?
