‘The Big Ratchet’

In her new book, Ruth DeFries argues that we have continually created new technologies that allow our numbers to grow. But each new invention creates a new problem—which we solve with yet another innovation that creates the next problem. Will we be able to sustain this so-far successful cycle past the great leap in technology and population of the last century?
