Solving this problemIntroduction Ecology is the study of the interaction between living and not living things. It begins with an organism, which is a living thing. All organisms make community and then an ecosystem. Nowadays our planet faces with different ecological problems such as water pollution, air pollution, climate change, nuclear issue, toxins, acid rains, Earth pollution, radioactive pollution and so on. Basically we are the main factor which make this problems, because of our selfishness. In fact everything is connects with each other and if there is one disease then from it will come other problems. Air pollution is contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere. Household combustion devices, motor vehicles, industrial facilities and forest fires are common sources of air pollution. Pollutants of major public health concern include particulate matter, carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide. Outdoor and indoor air pollution cause respiratory and other diseases, which can be fatal. Main body There are pollutants which pollute our environment. Carbon monoxides, hydrocarbons, sulphur oxides, nitrogen oxide and organic compounds those are examples of pollutants. They can evaporate and affect the atmosphere. Now I am going to tell you about two types of pollutants: primary and secondary pollutants. Now I am going to tell you about a statistic for air pollution at this moment: 1. In USA there is about 30.3 percent of worlds gas emissions. 2. About 35 percent of Chinese people live in very polluted cities, as they breath with the smoking air every day. 3. In Asia the air is so polluted and smog there is so thick that on some night they can`t see stars. 4. The statistic show that every year people from 200000 to 500000 die because of air polluted.
Impacts
Gas ozone is created by chemical reactions which have air pollutants. Naturally, this ozone definitely harm influence not just our body, organism and life but also life of other plants and animals. So as I have understood the effects of the air pollution are global warming, different lungs diseases, ice melting faster, more and more deaths, acid rain and polluted water. Solving this problem There are many way for solving these problems. For example from government side: Science also must participate in it. They can adopt different energy sources like solar or wind, which will definitely save an environment. Industries should install filters on smokestacks to purify the harmful gases. Scientist can create and instill to people perfumes and sprays containing no CFC`s. In my opinion everything start from us and we should all be responsible for it, not just government or scientists. We also can do some basic acts which make our environment cleaner. As an example we can change cars into bikes or, as I have mentioned before, bio cars. It will not just make environment cleaner but also makes us fitter and healthier. Basically we should just make beans for recycling and not as it is in developed countries. Conclusion Air pollution is the introduction of chemicals that harm human, plants, animals. It is the main cause of global warming and cancer. There are different causes like: smokestacks of factories and powerplnts, motor vehicles, buses, cars and aircrafts, chemicals, fires, volcanoes, nuclear weapons and so on. As a conclusion we don`t have much time to start caring about our future, we must start at this moment. Date: 2016-03-03; view: 2193 |
