In March 2025, a harmful algal bloom caused by Karenia mikimotoi began off South Australia’s Fleurieu Peninsula, leading to mass marine deaths, economic damage, and health issues for beachgoers. The bloom, driven by a combination of a marine heatwave, nutrient-rich floodwaters, and a rare cold-water upwelling, has made many beaches unsafe for swimming, surfing, or fishing. Losing access to these “blue spaces” has removed important physical and mental health benefits, contributing to eco-anxiety and “solastalgia” in affected communities. Despite the grief, the disaster has spurred citizen science, wildlife rescues, and advocacy for environmental action. Experts encourage finding alternative ways to connect with nature to support wellbeing during the crisis.
