This problem seems to be from an over fertilization of land. Placing a ban on the use of fertilizers should be taken in to consideration. I’m surprised no environmental friendly fertilizers have been developed; ones that would feed the soil but have a shorter nutrient life or ones that don’t feed algae. The algae seem to be growing more rapidly due to fertilizer running off into water sources. Therefore when the algae has no more oxygen to grow, it dies off, creating red tide, the dead zone, furthering the devastation in the marine environments.
