What Is Botulism?
Botulism is a plague brought on by a toxin produced by the bacterium Clostridium botulinum.

Whereas mostly related to meals poisoning in people, in wildlife—particularly birds—botulism may cause mass die-offs nearly in a single day.

A Disaster Made Worse by Local weather Change
As local weather change drives extra excessive climate occasions and better temperatures, the environmental situations that foster botulism outbreaks have gotten extra widespread. Extended warmth waves, drought, and poor water high quality all contribute to the issue. These outbreaks are now not remoted incidents—they’re changing into annual occasions in some areas.

- Volunteer: We might love your help, please have a look at the methods you may become involved with WIRES.
A Shared Accountability
Botulism is a pure phenomenon, however its rising severity is a symptom of wider environmental points that demand our consideration. By performing early and dealing collectively, we are able to shield our valuable wildlife from this merciless and silent killer.
