According to the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), less than 25% of the Earth's land surface has escaped substantial impacts of human activity- and by 2050, the IPBES experts estimate this will have fallen to less than 10%. Land degradation already cost the equivalent of about 10% of the world´s annual gross product in 2010 through the loss of biodiversity and ecosystem services, and costs will increase as the rate of species extinction accelerates.
