We recently wrote about the problems associated with plastic pollution, but what about other kinds of ocean pollution?
Nutrient pollution can be a big problem. Chemical run-off (mostly from fertilizer) can lead to a process called eutrophication where excess nutrients can result in dead zones. The dead zones are created when the extra nutrients increase algal blooms, which consume much more oxygen than normal. When the algae dies and sinks to the sea floor, the decomposition process can actually deplete surrounding waters of oxygen completely.
Some scientists are now suggesting that dead zones could be reduced by putting the ocean on a ‘pollution diet’. Check out this great article from The Epoch Times about the idea of starting a ‘pollution diet‘ in order to eliminate dead zones.
