A landmark report reveals that the world must change the way it produces food to avoid a biodiversity collapse

Conservation comebacks for wild tigers, tuna and green​ sea turtles prove that global nature loss can be reversed, ​scientists have said. ​But a report warns food production must be the next ​“positive tipping point​” if the world is to avert biodiversity collapse.

The World Wildlife Fund (WWF) analysed nearly 36,000 animal populations and more than 5,000 species, producing the largest ever database of vertebrate wildlife. Scientists found populations had declined by an average of 73% since 1970, showing that “nature continues to be degraded at an alarming scale”, with “no sign of losses slowing”.
