An algal bloom has already formed in the Black Sea this year. It’s an annual occurrence in many bodies of water around the world.

Algal blooms form wherever there is an excess of nutrients in the system. Industrial farming techniques produce a concentration of fertilizers and manures, which are then washed into lakes and rivers, and on into the seas. Certain industries’ waste water also contains nutrients for the algae to feed on.

Algal blooms can cause significant problems for marine life by using up all the oxygen in the water. Some algae secrete neurotoxins that can impair or kill humans and pets that enter the water.

Reducing the nutrient source is an important step in containing algal blooms.
