Knowing the causes of water pollution will help you to avoid contaminating the water.
But first what is water pollution? Well it can be described as the contamination of water sources, for example rivers, oceans. This occurs when pollutants are directly or indirectly dumped into the water without adequate treatment to remove harmful compounds.
Did I mentioned that on an average 250 million people worldwide die because of diseases related to water pollution?
One big step for every one of us can take to prevent water pollution is to minimize water contamination at every possible level. This way we can save clean water for the future generations.
Next I described three of the most important water pollution causes.
Sewage and wastewater
Everyday we perform tasks which make use of existing water, tasks like cooking, doing laundry, washing our cars. This waste of water and soluble waster (called sewage) is treated, cleaned and dumped into the sea or river. Even if its treated it will never be same as fresh water. In other less developed countries this sewage is not treated but dumped directly in to the sea. What we can do is every time we use water to use it wisely and to minimize the usage.
Oils
Oils which we drop into the sea form a tick layer on the water surface because these do not dissolve in the water. The layer can stop marine plants from receiving enough light for photosynthesis. Of course that this is also harmful for fish and marine birds.Atmospheric
Atmospheric deposition is the pollution of water caused by air pollution. Each time the air is polluted by our cars we drive or by industrial machines the chemical elements are mixed with water particles in the air and form a toxic substance. This falls as acid rain to the ground and gets in to the natural water sources.
Now that you know about the most important causes of water pollution and their effect you do not have any excuse to not take measures to reduce pollution and protect the future of your children.
