Manatees face serious welfare threats from boat strikes, cold stress, red tide poisoning and habitat loss that make them one of the most welfare-imperiled marine mammals in North America.
Manatee welfare represents a convergence of multiple anthropogenic threats creating an ongoing welfare crisis. Mass starvation events from seagrass loss, boat strike injuries, cold stress and red tide poisoning create both acute suffering and chronic welfare compromise. Individual manatees with boat strike injuries may survive with significant permanent impairment. The dependency on artificial warm water refuges at power plants creates vulnerability when these close. Addressing manatee welfare requires systemic interventions: boat speed restrictions in manatee habitat, water quality restoration supporting seagrass recovery, and climate change mitigation reducing extreme cold events and harmful algal bloom frequency.
