Seventy five per cent of the land surface has been significantly altered, and among assessed groups of mammals and birds, one in four species are at risk of extinction. The average abundance of native species in most major terrestrial biomes has fallen by at least 20 per cent and land degradation has reduced productivity in 23 per cent of the global terrestrial area.
This crisis not only threatens the diversity of life on Earth. Ongoing degradation and changes to ecosystems pose further risks to people through threats to food, energy and water security, as well as being a significant driver of climate change. Read more
