A harmful algal bloom, fueled by a marine heat wave, has been choking South Australia’s coastline, turning once-colorful ecosystems filled with thriving marine life into underwater graveyards. The bloom has killed about 15,000 animals from over 450 species, according to observations on the citizen science site iNaturalist. And it has poisoned more than 4,500 square kilometers (1,737 square miles) of the local waters – an area larger than Rhode Island – littering beaches with carcasses and ravagi
