Bald eagles return to the southern Great Lakes after near extinction

4 weeks ago 27



The bald eagle population in southern Ontario has made a remarkable recovery after near extinction due to DDT, symbolizing hope for both wildlife and human health.

Emma McIntosh reports for The Narwhal.


In short:

  • The pesticide DDT nearly wiped out bald eagles in North America, causing their numbers to plummet in the mid-20th century.
  • Decades of conservation efforts have led to a significant recovery, with Ontario declaring bald eagles no longer at risk in May 2023.
  • Despite the success, bald eagles now face new threats from climate change and emerging contaminants.

Why this matters:

The resurgence of bald eagles is a testament to the effectiveness of environmental regulations and conservation efforts. It speaks to a broader issue of how human activities impact both wildlife and human health, emphasizing the need for continued vigilance and action.
