Having to search farther and longer for our resources isn’t the only new hurdle we face. Climate change could also constrain growth. A steady stream of evidence now indicates that the planet is warming quickly and that the economic impact on agriculture, our built environment, ecosystems and human health could, in time, be very large.
In the last century, our population on this planet has quadrupled, and most of us now live in cities. At the same time, new technologies – from antibiotics to jet planes to the internet – have vastly extended our power as individuals, groups, and societies.
