Water

Now i am going to tell about the importance of water. Water is a chief component on earth where everyone should depend on it. For cleaning our ass also sometimes water is needed. For examining whether life is existing on terrestrial planets also, scientists need water traces. Though our earth is covered 3/4th of water, most of the water is not useful for humans. Only the water from polar ice caps is consumable and good for humans. So, humans are doing experiments on non-usable water resources and trying to convert that into good water. Most of their experiments are quite successful and they are looking for cost effective. Because treatment of such water is a difficult process and needs great amount to set-up such treatment plants. So, here also cost is playing major role. Let us hope for the good and cheap price of those plants.
