Don’t get me wrong. Technology is absolutely essential in the fight against ecological breakdown. We need all the efficiency improvements we can get. But scientists are clear that they will not be enough, on their own, to fix the problem. Why? Because in a growth-oriented economy, efficiency improvements that could help us reduce our impact are harnessed instead to advance the objectives of growth – to pull ever-larger swathes of nature into circuits of extraction and production. It’s not our technology that’s the problem. It’s growth.
