In Montreal, Canada, delegates from nearly 200 nations have wrapped up the U.N. biodiversity summit, known as COP15, with an agreement to protect at least 30% of the Earth’s land and oceans for wildlife by 2030. The landmark agreement seeks to halt the Earth’s sixth major mass extinction event, currently underway due to human activity. As part of the deal, Indigenous communities will have an increased role in protecting wildlife. Lands inhabited by Indigenous peoples hold 80% of the world’s remaining biodiversity. The World Wildlife Fund called the agreement “a win for people and planet.” But the Wildlife Conservation Society criticized it for focusing on 2050 deadlines, writing, “That will be far too late for us to halt and reverse biodiversity loss and address related challenges such as climate change.”
