THE EARTH, THE AIR, THE LAND, AND THE WATER ARE NOT AN INHERITANCE FROM OUR FOREFATHERS BUT ON LOAN FROM OUR CHILDREN. SO WE HAVE TO HAND IT OVER TO THEM AT LEAST AS IT WAS HANDED OVER TO US.
Water Pollution
Water pollution releases substances into subsurface groundwater or lakes, streams, rivers, estuaries, and oceans to the point where the substances interfere with the beneficial use of the water or ecosystems' natural functioning. In addition to the release of substances, such as chemicals, trash, or microorganisms, water pollution may also include the release of energy, in the form of radioactivity or heat, into bodies of water. Water bodies can be polluted by various substances, including pathogenic microorganisms, putrescible organic waste, fertilizers and plant nutrients, toxic chemicals, sediments, heat, petroleum (oil), and radioactive substances. Several types of water pollutants are considered below. (For a discussion of the handling of sewage and other forms of waste produced by human activities, see waste disposal and solid-waste management.) Water pollutants come from either point sources or dispersed sources. A point source is a pipe or channel, such as those used for discharge from an industrial facility or a city sewerage system. A distributed (or nonpoint) head is a vast unconfined area from which various pollutants enter the water body, such as the runoff from an agricultural area. Point sources of water pollution are more accessible to control than dispersed sources because the contaminated water has been collected and conveyed to one point where it can be treated. Pollution from distributed sources is difficult to control. Despite much progress in building modern sewage-treatment plants, dispersed sources continue to cause a significant fraction of water pollution problems.
Water Conservation
Water conservation is using water efficiently to reduce unnecessary water usage. According to FreshWater Watch, water conservation is important because fresh, clean water is a limited resource and a costly one. As a homeowner, you're probably already well aware of the financial costs of inefficient water use. Conservation of this natural resource is critical for the environment — and our wallets. Water conservation is a complex topic. It's not just about saving water. It's about saving money.
