Fireflies at risk of extinction due to the climate crisis, light pollution, and more


The world is getting darker — and I don't just mean due to the looming threat of the climate crisis. According to new research, fireflies — of which there are more than 2,000 species on Earth — are at risk of extinction.

Of the 2,000 or so species of fireflies, between 125 and 200 can be found in the U.S. Even though there has been evidence that firefly populations have been dwindling for a while, fireflies are still not protected by the country's Endangered Species Act.
