Why we are to blame for epidemics and only decisive ecological action can save us from ever new plagues. Viruses have always influenced humanity - and now humans themselves are creating the conditions for new infectious diseases. By changing the world, we trigger pandemics that we can no longer control. Evolutionary biologist Matthias Glaubrecht embarks on an exciting quest to uncover the true origins of the coronavirus, the role animals play in this, and how the ever-accelerating destruction of natural habitats and biodiversity conjures up new plagues. Glaubrecht has the perspective of a well-traveled biologist who studies the destruction of nature, and he can write about it like few others.
