U.S. Butterfly Population Declines by Over 20% This Century

The butterfly population in the United States has declined by more than a fifth since the start of the century, according to new research. The drop raises concerns about pollination and ecosystem health, as butterflies play a crucial role in supporting biodiversity.

Scientists attribute the decline to habitat loss, climate change, and pesticide use. Conservationists are calling for stronger efforts to protect butterfly habitats and promote sustainable environmental practices to prevent further losses.
