Effects of water pollution on marine life

An effect of water pollution is the death of the lakes, as a consequence of rising fertility due to the increase in nutriments, especially phosphates and nitrates which increases the quantities of plankton, plants and marine life. Little by little, the lakes decrease in width and disappear.

The chemical water pollution affects marine life in different ways, depending on the nature of the polluting agent. The copper and chrome salts are toxic for algae and marine life. Plankton is strongly affected by numerous pesticides and herbicides. Synthetic detergents are very toxic for marine life, and water pollution with this agent affect the microbial flora. Marine life is easily affected, but the most deaths are due to lack of oxygen in the polluted water, and dumping of pesticides and toxic residue.
Severe problems can also appear in water pollution with heavy metals, especially with mercury, which accumulates on the food chain. The consequences resulting from the pollution of marine life with mercury, constitutes an alarm signal to the irresponsible behavior of humankind.

In fact, water pollution has a direct but also an indirect effect on human kind, which requires that we take measures against water pollution of marine life and the environment. Unfortunately, the technologies in maintaining bacteriological water pollution levels down, aren’t yet implemented in a large scale as it should be.
