There is only one known planet in the universe capable of meeting humanity's needs – Earth. And yet, our understanding and appreciation of the underlying complexity that makes it function remains limited. If we were able to grasp the transformative potential of biodiversity – specifically how it relates to biocomplexity – how might we change our behavior?
In this episode, Nate is joined by ecologist Thomas Crowther to discuss the critical importance of biodiversity as an intricate web of life that supports all other living beings, not just through the sheer number of species, but because of the complexity of interactions within ecosystems. Thomas highlights the power of data in empowering individuals to make informed choices that positively impact nature, and the critical need to address inequality in order to foster ecological recovery.
Could the power of data and knowledge catalyze humanity into valuing biodiversity for the sake of preserving ecological stability? How do local communities and initiatives play a key role in revitalizing productive ecosystems, and how can we change our patterns of consumption to better support them? And perhaps most importantly, if we come to understand the critical interconnectedness of the biosphere, might we finally rediscover our place within it, as one species among millions fostering life on this Blue-Green Earth?
About Thomas Crowther
Thomas Crowther is an ecologist studying the connections between biodiversity and climate change. He is chair of the advisory council for the United Nations Decade on Ecosystem Restoration, as well as the founder of Restor: an online, open-data platform for the global restoration movement. He was also a professor in the Department of Environmental Systems Science at ETH Zurich, where he started Crowther Lab, an interdisciplinary group of scientists exploring how global-scale ecological systems interact to regulate the climate. In 2021, the World Economic Forum named Thomas a Young Global Leader for his work on the protection and restoration of biodiversity.
