What happened during the mass extinction

Species decline due to rise in temperature

In the report of the Intergovernmental Panel on Climate Change (IPCC), approved by all governments, the experts warn that climate change alone puts 20 to 30 percent of the species known today at risk of extinction if warming continues at the current rate.

The reason is simple: ecosystems are changing, species are being displaced, cannot find new habitats - and are dying out. The experts assume that species decline will occur with a "moderate" increase in the average temperature of 1.25 to 2.5 degrees Celsius. This is now considered to be no longer avoidable.

No thought of future generations

Humans do not limit themselves to using up nature at the rate at which it can regenerate. Worldwide, for every ten trees that humans cut, only one is replanted - without thinking about what we will leave behind for future generations.

Environmental destruction as the "greatest market failure"

Even economists are now warning of the consequences. Even from a purely cost-benefit point of view, ecosystems perform great services and provide important goods.

The British economist and government advisor Nicholas Stern describes the environmental destruction caused by climate change as "the greatest market failure the world has ever seen."
