There is no planet B a handbook for the make or break years

"Almost every year since records began, our species has had more energy at its disposal than it had the year before. For the last 50 years, the growth rate has averaged 2.4% per year, more than tri-pling in total over that time. For the century before that it was more like 1% per year, and as we go back through history, the growth rate looks lower still but nevertheless positive, give or take the odd blip. We have been getting continually more powerful, not just by growing our energy supply, but by using it with ever more efficiency and inventiveness. In doing so, we have been increas-ingly affecting our world, through a mixture of accident and de-sign. The restorative powers of our planet, meanwhile, have re-mained broadly the same, so the balance of power has been shift-ing - and it has now tipped. Throughout history, the dominant cultures have treated the planet as a big and robust place, compared to everything we could throw at it--and that approach has not, generally speaking, come back to bite us."--
