As we know that, we are surrounded by water-70% of the Earth’s surface is covered by water. I don’t understand why yet there is talk about a water crisis, the need to use water wisely, and duty to prorect our rivers, wetlands and oceans… Why?

As the word population grows and demand for water increases, and as Earth’s supply of freshwater (stored in aquifers, surface waters and the atmosphere), becomes more polluted, of course the access to water becomes more difficult.

The consequences are manifold, from health impacts and regional conflicts over scarce water resources, to harmful effects on plant and animal species from polluted water  bodies.
