What is causing the toxic water in Florida?

Florida has struggled for almost two decades to control the blue-green algae that periodically carpets Lake Okeechobee and threatens tourism on the coast.

A red tide or HAB results from the rapid growth of microscopic algae. Some produce toxins that have harmful effects on people, fish, marine mammals, and birds. In Florida and Texas, this is primarily caused by the harmful algae species Karenia brevis.

Why is Lake Erie so dirty?

Lake Erie’s algae blooms are caused by runoff pollution. This type of pollution occurs when rainfall washes fertilizer and manure spread on large farm fields into streams that flow into Lake Erie. This fuels a bumper crop of algae each year that can make water toxic to fish, wildlife, and people.
