Bird flu is killing thousands of seals

Avian influenza is killing tens of thousands of seals and sea lions in different corners of the world, disrupting ecosystems and flummoxing scientists who don’t see a clear way to slow the devastating virus. The worldwide bird flu outbreak that began in 2020 has led to the deaths of millions of domesticated birds and spread to wildlife all over the globe. This virus isn’t thought to be a major threat to humans, but its spread in farming operations and ecosystems has caused widespread economic turmoil and environmental disruptions. Scientists say seals and sea lions, in places as far apart as Maine and Chile, appear to be especially vulnerable to the disease.
