Are red tides harmful to humans?
Why are red tides harmful?

Are red tides caused by humans?
Here are some answers to common questions about red tide. … But while red tide itself is natural, scientists say there’s evidence that massive blooms may be partly caused by human activities, such as fertilizers washing off farms and the discharge of fertilizer-laden water from Lake Okeechobee into the Gulf of Mexico.

What is a red tide caused by?
This bloom, like many HABs, is caused by microscopic algae that produce toxins that kill fish and make shellfish dangerous to eat. The toxins may also make the surrounding air difficult to breathe. As the name suggests, the bloom of algae often turns the water red.

Why are red tides dangerous?
