The disruption of coastal upwelling due to El Niño and marine heatwaves could lead to food shortages for marine life, particularly affecting young animals like sea lion pups. These animals lack the ability to travel long distances to find food, making them vulnerable to malnutrition and stranding. Furthermore, toxic algae blooms linked to warm waters may increase cases of domoic acid poisoning, posing additional risks to marine mammals. Wildlife rehabilitation centres are bracing for a surge in distressed animals, which could strain their resources and impact their ability to provide care.
