It has been suggested that it is the down to individual aquifers and wells). It has been suggested that it is the leading worldwide cause of deaths and diseases, and that it accounts for leading worldwide cause of deaths and diseases, and that it accounts for the deaths of more than 14,000 people daily.the deaths of more than 14,000 people daily.All about Water pollution2.influence3.solution1.Cause Nowadays, water pollution is deteriorating. Rivers, lakes and even oceans all over the world are becoming polluted by garbage and dangerous chemicals. Oil and other Chemicals can kill fish and make water unsafe for drinking. Before we think about what should we do to solve this problem ,we should first know what cause the problem. Cause1.Natural pollution Due to the dissolution of geological, atmospheric precipitation leaching, erosion on the ground, mix the various pollutants into the water 因地质的溶解作用,降水对大气的淋洗、对地面的冲刷,挟带各种污染物流入水体而形 成2. Man-made pollution1.industrial wastewater (工业废水)2.Daily life sewage (生活污水)3.Pesticide and fertilizer pollution (农业化肥污染)These do damage to the quality of water.BACKWater Pollution Water Pollution distribution distribution Water pollution is one of the most serious problems that mankind faces today.1.For business or industry, it affects products’ quality , increased corrosion of products, and so on.2.For individual, it does damage to the human’s healthy.There are many influence that we can’t describe them by words.
