A biodiversity crisis is reducing the variety of life on Earth. Under pressure from land and water pollution, development, overhunting, poaching, climate change and species invasions, approximately 1 million plant and animal species are at risk of extinction.
One ambitious proposal for stemming these losses is the international initiative known as 30x30: conserving and protecting at least 30% of Earth’s surface, on land and at sea, by 2030.
