A great deal of water pollution happens not from one single source but from many different scattered sources. This is called nonpoint-source pollution.Photo: Above: Point-source pollution comes from a single, well-defined place such as this pipe. Below: Nonpoint-source pollution comes from many...
Water pollutionstems from many sources and causes, only a few of which are discussed here. Rivers and streams demonstrate some capacity to recover from theeffects of certain pollutants, but lakes, bays, ponds, sluggish rivers, and oceans have little resistance to the effects of water pollution. ...

Nonpoint-source pollution, however, comes from diffuse sources and requires much greater effort to address. Loss of water, oxygen demands, and nutrient effects are examined in detail. Large impacts have been, and are, expected with continued water abstraction. Solutions include litigation and at ...
People living in the city could move around on small boats driven by electricity, so there would be no air pollution from the burning of gas. There would be platforms outside the main wall for ships bringing supplies. People could also travel to the mainland by motorboat or water plane. Wh...

annual limit for PM2.5 set by the European Union is 25 micrograms per cubic meter, or 2.5 times more than the WHO recommendations. Since most of the fine particles and other air pollutants in Europe come from the combustion of fossil fuels, it is urgent to switch to other sources of ...
As a matter of fact,we have many methods to avoid or reduce the harm of air pollution.On the one hand,the major and largest sources of air pollution come from industrial pollution and automobile exhaust.Therefore,we should try to develop new energy to replace the tradition ones;in addition,...
Urban stormwater and snowmelt pollution contributes significantly to the deterioration of surface waters quality in many locations. Consequently, the sources of such pollution have been studied for the past 50 years, with the vehicular transportation sector and the atmospheric deposition identified early...
Such a warming could cause a massive melting of the polar ice caps, resulting in the flooding of many coastal areas. Ozone depletion. Ozone is a form of oxygen whose molecules contain three atoms (O 3 ) rather than two atoms (O 2 ). Ozone occurs in very small concentrations in upper...
