Did that are affected by pollution are

Did you know that there ispollution all over the world?  Well todayI am going to be talking about pollution in Wisconsin. Everyone needs clean water for something.  People use water for drinking, growing cropsand to operate factories.  Many differentwildlife animals depend on water to live such as fish, beavers, otters and anyanimal that drinks water to survive.

 There are lots of pollutants’ that can harm and contaminate our rivers,streams and lakes.  Soil, nutrients andbacteria are the three most common.  Raincan be a very big problem because when it rains and the rain doesn’t soak intothe ground the rain can bring that dirt into our streams and rivers.   When the soil gets washed into the streamsand rivers it can kill fish eggs and tiny animals.  Soil can also get into fish gills and clogthem up.  It can also block out the sunwhich can result in plants dying because of the lack of sun light.  The nutrients in fertilizer can also causeproblems in lakes, ponds and reservoirs.

 Algae grow from nitrogen and phosphorus and it can turn the lakegreen.  Bacteria usually from sewagespills can pollute the water.Two types of water resources that are affected by pollutionare ground water and surface water. Pollution can occur in two different ways.

  There is two different ways in whichpollution can occur. According too explainthatstuff.com/waterpollution When pollution comes from a single locationsuch as a discharged pipe attached to a factory, it is known as point-sourcepollution.  Some examples of point sourcepollution are oil spills from a tanker, a discharge pie from a smoke stack orsomeone pouring oil from there car down a drain.  A big source of water pollution happens notfrom just one single source but from many different scattered sources.

  This pollution is called nonpoint-sourcepollution.  At the point whenpoint-source pollution enters the environment the place most affected isusually the area immediately around the source. For an example when an oil tanker accidentally occurs the oil slick isconcentrated around the tanker itself and in the right conditions the pollutiondisperses the further away from the tanker you go.

  This is not as likely to happen from a non-pointsource pollution from the definition enters the environment from many differentplaces at once.
