We’re currently caught in two loops: One is that more population growth and more global warming together are pushing up food prices; rising food prices cause political instability in the Middle East, which leads to higher oil prices, which leads to higher food prices, which leads to more instability. At the same time, improved productivity means fewer people are needed in every factory to produce more stuff. So if we want to have more jobs, we need more factories. More factories making more stuff make more global warming, and that is where the two loops meet.

But Gilding is actually an eco-optimist. As the impact of the imminent Great Disruption hits us, he says, “our response will be proportionally dramatic, mobilizing as we do in war. We will change at a scale and speed we can barely imagine today, completely transforming our economy, including our energy and transport industries, in just a few short decades.”

We will realize, he predicts, that the consumer-driven growth model is broken and we have to move to a more happiness-driven growth model, based on people working less and owning less.
