Each species in an ecosystem relies on one another. From the millions of fungi in the soil to the macrofauna that dominate the landscape, from the biggest predator to the smallest prey, each organism helps create a livable, sustainable ecosystem in which all the others can thrive. In his commercial debut, renowned ecologist and leader of the Trillion Trees Study Dr. Tom Crowther will take readers beneath the canopy to show how everything within and around the trees connects through an intricate series of feedback loops.

But feedback loops aren’t just critical to understanding how ecosystems function and persist over time, they also underpin the most incredible developments in the universe from the birth of the stars to the evolution of species to the creation of language itself. These loops are the most powerful mechanism of change we have, and if we understand how they work, both in nature and in society, we’ll have the tools to revive the rich, diverse, and sustainable environments we love and need.

Grounded in original research and containing of dozens of real-world stories from across the globe, Dr. Crowther will provide readers with a renewed sense of awe in the power and beauty of nature, and a new paradigm for how to engage with our environment and our society to create transformative change.

Dr Thomas Crowther runs the Crowther Lab at ETH Zurich, where he is a professor in the Department of Environmental Systems Science, conducting original research and teaching the science of climate change. His research is regularly published in top journals such as Nature, Science, and Proceedings of the National Academy of Sciences, and he has been featured in popular media including The New York Times, The Washington Post, and The Guardian. He speaks regularly at conferences like Davos and the UN Convention on Climate Change and consults with major companies including Google and Salesforce.
