Toxic algae blooms threaten Southern California marine life

Marine biologists warn that sea life off the Southern California coast is at serious risk due to toxic algae blooms. These blooms are becoming more frequent, largely because of climate change. Scientists have noted a sharp increase in the number of harmful algal blooms in recent years. Dave Bader, a marine biologist at the Marine Mammal Care Center in San Pedro, explained that these events used to occur every four to seven years. Now, they happen more often, causing deaths among sea lions, dolphins, and other marine mammals. Bader mentioned that the situation has worsened over the past four years, especially in 2023 and into this year. During harmful algal blooms, algae grow quickly and may produce toxins that can harm both marine life and potentially humans. Climate change is significantly contributing to the rise in these toxic blooms. Bader pointed out that ocean acidification and pollution from burning fossil fuels are affecting ocean chemistry. Additionally, toxic runoff from wildfires is complicating the issue. The ongoing algal bloom crisis poses serious threats to marine animals. Bader warned that if this continues, children may someday only know about these creatures from books. He expressed concern about a future ocean without whales, sharks, and dolphins. Bader and his team are working hard to rescue sick marine mammals. Unfortunately, once a dolphin is infected by the toxic algae, recovery is unlikely. Bader is urging the community to support their efforts through donations. He believes that everyone can play a role in making a change.
