Pollution is causing irreplaceable damage to the planet, and it is increasing every passing year at an alarming rate. It is a problem of environmental pollution, but what exactly is this pollution, why is it matter of such a big concern to understand. Humans keep adding impurities on a large scale to the surrounding, and this keeps going on a daily basis.
All the technologies, all these developments, have happened with just one simple objective in mind: to make life comfortable: you can do things faster, to do things to make life comfortable and as a result of a lot of good things happen: people live longer, and health facilitates are batter.
This has given rise to globalization, communication has become good, the transportation has been good and material comforts are plenty. But having said all that, if you go over each one, one by one in a line, eventually this leads to some kind of problems. We then probably can go into details that mining people will do harmful things they will go down underneath the earth for 3 kilometres, 4 kilometres….
If you can say that God has made everything under the ground so it is not a disturbed man has been able to bring it up and we have all kinds of problems that come up… we some for good things, but then again there will be some associative problems we all can talk about new chemicals being added and the problem of pesticides we can talk about transportation and all.
We can drive through cities quickly, but then again the issues and the problems that come from transportation and automobile engineering. So also in power generation, and all kinds of problems not only the SO2, NO2 particulate matter, but CO2 is something that is not ignorable. In civil engineering, also there are many things that lead to problems as well. What was happening is, when these things were developing, people were very happy without considering the after-effects the backlashes of the technology. Everything has a good side as well as a bad side. So, there were also the backlashes that started coming in, then the people from science, people from the medical sciences and environmental health, they came up and said there are certain problems: things are not so perfect, the ways of progress human are following cannot be sustained, it is impossible.
Air pollution is the addition of chemicals indoor particles to the atmosphere in concentrations that are harmful to life on Earth. It is very important to know that these pollutants are naturally added to the atmosphere all the time. It is just the excess addition by human processes that causes serious problems sulphur dioxide and nitrogen oxide are reactive gases that damaged buildings and plants and can also increase respiratory problems in humans they are emitted from the combustion of fuel such as a coal-burning power plant and nitrogen oxide are also heavily emitted from automobile exhaust particulate matter refers to small solid or liquid particles that are released from many natural sources such as fires dust and volcanic eruptions but are also emitted by humans during construction and industrial processes PM 2.5 and 10 refer to the size of these particles another major pollutant is carbon monoxide which is toxic to humans as well as other animals. In low concentrations given that it reduces oxygen circulation in the body. Carbon monoxide is mostly emitted from automobile exhaust all of these pollutants. So far sulphur dioxide, nitrogen oxides particulate matter and carbon monoxide are all considered primary pollutants that are released directly into the air now let’s considered a secondary pollutant ozone environmental scientists talk about ozone at two regions in the atmosphere ozone in the upper stratosphere is very helpful in blocking ultraviolet radiation. The ground level ozone is very harmful to respiratory systems of plants and aminals. Ozone is a secondary pollutant, a secondary pollutant is produced when the primary pollutants react with other atmospheric chemicals with ozone, for example, this can occur as nitrogen dioxide is released from automobile exhaust as a primary pollutant and react with oxygen and sunlight in the atmosphere the result is the formation of the secondary pollutant ozone. There are other air pollution processes as well. In urban areas air pollution is dependent on emission retes topography and weather conditions for example if the city is located in the low valley.
