Water is a fascinating compound. It drives life on our planet and helps make it unique from other planets in the solar system. Without water, life wouldn’t be possible. Simple organisms, such as bacteria and even slime molds, need only a small number of water molecules to survive.
On the other hand, large organisms such as whales and humans have trillions of individual water molecules. With so many different organisms having different needs for water that depend on their size, quantity, and complexity, it’s no wonder there’s a major problem with adequate water supplies for everyone on this planet.
Water is a renewable resource, but its overuse and pollution make it unfit for use. Sewage, agricultural chemicals and industrial waste pollute the water with nitrates, metals and pesticides.
Forest and other vegetation cover slow the surface runoff and replenish underground water.
Water harvesting method can also be used to save surface runoff. Canals used for irrigation should be properly checked for water losses through seepage and evaporation.
Rain water harvesting is the process of collecting rain water from roof tops and directing it to an appropriate location where it is stored for future use.
