Why do lakes turn green?

The more phosphorus present, the more abundant algae become and the greener the water gets.

What exactly is a dead zone?

A “dead zone” is known in scientific literature as hypoxia, which means low oxygen.

Can a dead zone be fixed?

Dead zones occur around the world, but primarily near areas where heavy agricultural and industrial activity spill nutrients into the water and compromise its quality accordingly. … Fortunately, dead zones are reversible if their causes are reduced or eliminated.

Why are dead zones bad?

Dead zones are the most severe result of eutrophication. This dramatic increase in previously limited nutrients causes massive algal blooms. These “red tides” or Harmful Algal Blooms can cause fish kills, human illness through shellfish poisoning, and death of marine mammals and shore birds.
