Roughly 190 countries early Monday approved a sweeping United Nations agreement to protect 30% of the planet’s land and oceans by 2030 and to take a slew of other measures against biodiversity loss — a mounting under-the-radar crisis that, if left unchecked, jeopardizes the planet’s food and water supplies as well as the existence of untold species around the world.
The agreement comes as biodiversity is declining worldwide at rates never seen before in human history. Researchers have projected that 1 million plants and animals are at risk of extinction, many within decades. The last extinction event of that magnitude was the one that killed off the dinosaurs 65 million years ago.
While many scientists and activists had pushed for even stronger measures, the deal, which includes monitoring mechanisms that previous agreements had lacked, clearly signals increasing momentum around the issue.
