Backed by research, Dag explains to the reader how humans are affecting the earth's ecosystems. While we are a reasonably young species, we are causing changes that are already visible on a geological time scale.
The sudden rise in greenhouse gases and the loss of species have only been seen at few timepoints in earth history before. One of the major risks is that once tipping points are crossed, these changes initiate self-reinforcing feedback mechanisms. The thawing of permafrost could, for example, lead to the release of an enormous amount of additional greenhouse gases which will further heat the planet. If you want to know more about how close we are such tipping points, and if we can reverse these trends, you should read the book.
