Insects declining rapidly even in untouched ecosystems.

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.
