‘Point of no return’: Chris Packham leads calls for Rishi Sunak to attend Cop15

Conservationist says if world leaders do not go to the summit a strong deal to halt and reverse nature loss is at risk

Chris Packham is urging the British prime minister, Rishi Sunak, to attend a key nature summit to protect the planet for the sake of his great-grandchildren because we are very close to the point of no return".

The Cop15 biodiversity summit being held in Montreal from 7-19 December is the nature equivalent of the recent Cop27 climate summit in Egypt, with governments from all over the world expected to agree targets to halt the destruction of the natural world. But world leaders are not expected to attend the once-in-a-decade meeting where the next 10 years of targets will be agreed.
