Causes and Effects of Air Pollution
Of all the changes among present human life, those that affect the natural environment seem to hold the most serious implication for our Planet. For hundreds of years, people have been polluting the earth surface and atmosphere. The earth's own ability to absorb and purify minor quantities of pollutants has made a minimal effect as of yet, but these small changes can eventually build up over time, causing huge problems for later generations. A high percentage of people, through sheer ignorance, tend to ignore the amount of pollution we dump into our earth’s atmosphere daily. At the moment our earth is only slightly affected by pollutants in terms of human life, but when you start looking at the effects to environment and natural habitats that are slowly creeping towards higher levels, a breakdown of our ecosystems seems inevitable.
However while many people are aware that our careless use of hazardous chemicals and fossil fuels may leave the planet uninhabitable in the future, most over look the fact that they are also cause real damage to our bodies even at the level of pollution the world is in at the moment. Such pollutants cause damage to our respiratory system, leading to much shorter life spans among certain populations, effected mostly by geographical position, for example “World Health Organisation guidelines suggest that PM2.5 levels above ten micrograms per cubic metre are unsafe. The boffins have found (as the map shows) that almost every Chinese province has levels above that. Indeed, much of the country’s population endures air so foul that it registers above 30 on the PM2.5 scale, with Shandong and Henan provinces topping 50.” They also say that “For comparison purposes, the U.S. standard for average annual emissions is 15 on the PM2.5 scale, and the U.S. standard for 24 hour spikes is 35 μg/mg3. Thus, much of the Chinese population experiences average daily pollution over twice what the U.S....
