The world is gathering in Colombia for the UN biodiversity conference known as Cop16, a biannual pulse-taking of the living planet where actions to protect the natural world are agreed. At its last meeting in 2022, an ambitious roadmap for nature protection was put in place. As part of that Kunming-Montreal global biodiversity framework, the UN set a bold goal to protect 30% of the world's land and ocean by 2030—known as "30x30"—which was agreed by 196 countries and bodies such as the European Commission.
