Climate change is worsening the planet's biodiversity crises, making environments more deadly for thousands of species and accelerating the precipitous decline in the number of plants and animals on Earth, according to an international organization that tracks species health. Species of salmon and turtles are among those facing a decline as the planet warms. Atlantic salmon isn’t yet threatened with extinction, but its population dropped by nearly a quarter from 2006 to 2020, the International Union for Conservation of Nature, which tracks biodiversity around the globe, said on Monday.
