Insects are declining at an alarming rate, even in untouched ecosystems, a new study finds.
Why it matters
- Insects are vital for ecosystems.
- Declines seen even in undisturbed areas.
By the numbers
- 6.6% annual decline in insect abundance.
- 72.4% drop over 20 years.
- 38 years of weather data.
The big picture
- Climate change may be a key driver of insect declines.
- Highlights need for more monitoring and urgent climate action.
What they're saying
- Decline may correlate with rising summer temperatures, but other factors could be at play.
- Skepticism about truly untouched ecosystems.
- Questions about whether any insect species are thriving.
Caveats
- Study based on one location; other factors may contribute to decline.
What’s next
- More research needed to understand drivers of insect decline.
- Increased monitoring of insect populations in various landscapes.
