A deadly kind of algae might be answerable for the ongoing passings of many elephants in Botswana. Authorities said on Monday that a perilous blue-green algae seemed to debase a water hotspot for the creatures, which could have taken lives of roughly 330 elephants this year in the Southern African nation.

A poisonous sprout of cyanobacterium was found in water sources in the Seronga district and the disturbing elephant passings halted after the water evaporated. The elephants passed away from a neurological issue that appeared to originate from drinking the water.
