CONSERVATION  OF WATER

Water is a transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients.

IMPORTANCE OF WATER

Water can be used for direct and indirect purposes. Direct purposes include bathing, drinking, and cooking, while examples of indirect purposes are the use of water in processing wood to make paper and in producing steel for automobiles. The bulk of the world's water use is for agriculture, industry, and electricity.

WHERE DOES WATER COME

Water on Earth cycles from the oceans, where it evaporates from the surface, into the atmosphere, forms clouds, falls onto the land as rain, travels through wetlands, rivers, lakes and underground then returns to the ocean — collectively known as the Hydrologic cycle.

WATER POLLUTION

Water pollution occur when pollutants (particles, chemicals or substances that make water contaminated) are discharged directly or indirectly into water bodies without enough treatment to get rid of harmful compounds. Pollutants get into water mainly by human causes or human factors.
