Causes Of Water Pollution
Pollution of water is one of the main problems the world is facing today. And to add to the woes, almost all these problems are man-made for which the aquatic animals and plants are suffering the most.
Here are some of the main causes of water pollution:
- Sewage disposal - Sewage is the term given to wastewater carrying all forms of animal, especially human excreta. For our own hygiene purposes, the excreta we secrete everyday is flushed out of our habitats but we seldom give it a thought as to where they are going. They are carried through a complex channel system into the nearest water body, be it a river, sea or an ocean. Though sewage is biodegradable, it is the chemicals and sanitizers which the human use in their toilets, which are also flushed out with them, that cause the water pollution. These sanitary liquids, being harmful causes threat to the aquatic life when they come in contact with them.
- Industrial wastes - The wastes from the industries contains huge amounts of poisonous substances like asbestos, lead, mercury, nitrates, phosphates and sulfur, not to mention copious amounts of oils. These substances prove fatal to human beings: so it is understandable what harm they can cause to the delicate marine beings. Moreover, if the humans consume these affected fish for their food, their health can also get seriously harmed.
- Radioactive wastes - Most of the biggest nuclear power stations are located near the seas of the oceans. Now these power plants release copious amounts of radioactive emissions which go out onto the nearby water body, in the process affecting the water borne animals and plants there.
If the above listed causes can be checked, the problem of water pollution can be checked to a certain extent.
