The Effects Of Water Pollution

Water Pollution Over two thirds of Earth 's surface is covered by water. Less than a third is taken up by land. As Earth 's population continues to grow people are putting ever increasing pressure on the planet 's water resources. In a sense, our oceans, rivers, and other inland waters are being squeezed by human activities, not so they take up less room, but so their quality is reduced. Poorer water quality means water pollution. Water pollution is a frightening problem, which results high rate of chemicals going into our water, this is a humankinds problem, excessive fertilization, sewage waste, and radiation waste, leads to water pollution. We know that pollution is a human problem because it is a relatively recent development in the

For example, oceans. Around 80 percent of ocean pollution enters our seas from the land (Blythe, 2013). Virtually any human activity can have an effect on the quality of our water environment. When farmers fertilize the fields, the nitrogen and phosphorus applied to agricultural land, via synthetic fertilizers, composts, manures, bio solids, etc. Can provide valuable plant nutrients. However, if not achieved correctly, excess nitrogen and phosphorus can have negative environmental consequences (The Problem, 2015). Excess nitrogen supplied by both synthetic fertilizers, as highly soluble nitrate, and organic sources such as in manures can central in to groundwater contamination of nitrate. Nitrate polluted drinking water can cause blue baby syndrome. Together with excess phosphorus from these same fertilizer sources, eutrophication can occur downstream due to excess nutrient supply, leading to anoxic areas called dead zones (The Problem, 2015). The chemicals they use are gradually washed by rain into the groundwater or surface waters nearby. Sometimes the causes of water pollution are quite surprising. Chemicals released by smokestacks can enter the atmosphere and then fall back to earth as rain, entering seas, rivers, and lakes and causing water pollution. That 's called atmospheric deposition (The Problem,2015). Water pollution has many different causes and this is one of the reasons why it is such a difficult problem to solve (Blythe,
