Our planet was once populated by megafauna, big top-of-the-food-chain predators that played their part in balancing our ecosystems.

When those megafauna disappear, the result is a "trophic cascade," where every part of the ecosystem reacts to the loss.

How can we stay in balance?

George Monbiot suggests rewilding: putting wolves, lions and other predators back on top - with surprising results.
