How do algae blooms affect humans? When the algae eventually dies, the oxygen in the water is consumed. Elevated nutrient levels and algal blooms can also cause problems in drinking water in communities nearby and upstream from dead zones. Harmful algal blooms release toxins that contaminate drinking water, causing illnesses for animals and humans.
Can you get sick from algae bloom?

Why is algae bloom bad?
Harmful effects. As algal blooms grow, they deplete the oxygen in the water and block sunlight from reaching fish and plants. And when the algae eventually die off, the microbes which decompose the dead algae use up even more oxygen, which in turn causes more fish to die or leave the area.
Is algae in pool harmful to humans?
