Nature's Echo

Harnessing ancient feedback loops to heal a changing planet

By: Thomas Crowther

Nature wants to heal, and we can help.

We know that when Earth's ecosystems fall out of harmony, the damage can spiral out of control. But what if we could help nature to regain its balance?

As a leading ecologist, Professor Thomas Crowther studies not just how species work individually but how whole complex ecosystems work to regulate themselves. When we set the right conditions for nature to thrive, each species helps to support the life of every other species. This means not just planting trees, but taking into account the fascinating role of fungi and soil bacteria, as well as the free movement of wild animals.

By revealing how the feedback loops that generate sustainable ecosystems give rise to the stars, planets, and life; economic inequality and privilege; and the way we see the world, Nature's Echo shows how we can do our part so that nature can begin the vital process of healing itself.
