Water pollution is the contamination of streams, lakes, underground water, bays or oceans by substances harmful to any living thing. Water is a necessity to every living thing on Earth. Seventy-one percent of the Earth is covered by water, yet there is still not enough water to fulfill our needs. Only one percent of the water we have is fresh water, the other seventy percent is saltwater. The World Water Council claims that if we do not begin to conserve water now, we will not have any fresh water by the year 2025.
