Air pollution threatens the health of human beings and other living things on our planet. While often invisible, pollutants in the air create smog and acid rain, cause cancer or other serious health effects, diminish the protective ozone layer in the upper atmosphere, and contribute to the potential for world climate change. Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores are some sources of air pollution. Some air pollutants are poisonous.
Some contaminates can be noticed because of an odor, where some cannot because they are odorless. Air pollution is contamination of air by the discharge of harmful substances. We have many pollutants, which cause air pollution. Some examples are carbon monoxide and carbon dioxide. All of these pollutants can cause lot cancer, birth defects, brain and nerve damage, long-term injury to the lungs etc.
Fossil fuel burning releases sulphur dioxide, carbon dioxide, chlorofluorocarbons, and other dangerous gasses into the air. The presence of these hazardous gases in the atmosphere causes global warming and acidic precipitation; which in turn have increased temperatures, erratic rains, and droughts worldwide. Air pollution can also cause harmful effects in human health. These effects can be divided into short-term effects and long-term effects. Short-term effects, which are temporary, include illnesses such as bronchitis or pneumonia.
Pollution of the greenhouse gases is one of the biggest factors that cause it. These greenhouse gases carbon dioxide, methane from landfills , fossil fuels, nitrous oxide from fertilizers, and lastly carbon monoxide, all of these gases warm and hurt the atmosphere. Some of these gases are caused by natural things on earth like volcanoes , but humans are the ones who are responsible for most of these gases in the air(“Global Warming”). Global warming is warming of the regions and that is what causes the severe weather and melting of the ice caps. Global warming is the result of human air pollution of the greenhouse gases into the environment and it is killing our planet.
Secondary pollutants are caused due to mixing of primary pollutants. Sources of pollution are human, plants, animals, power, cars, burning stuffs, natural dust, sulphur, chlorine and ash particles, volcanic activity. Dust, storm and smog are causing huge health hazard in the lives of UAE population. All these harmful em... ... middle of paper ... ...my understanding of the causes of air pollution I will be able to bring awareness not only in my group but also people living around me. According to me, immediate measures to curb air pollution will definitely bring down the level to some extent.
The biggest health risk that i would like to be seen met for me and my family is probably pollution. There are many different types of pollution and each one is caused by different things like smog and improper waste disposal. One thing that will always be true about pollution is that its a problem that humans are causing by Deforestation and exhaust from vehicles and manufacturing. However its not just humans that can cause pollution volcanic eruptions also cause pollution of the air and can even cause forest fires. Pollution damages not only the earth but the creatures who live on it like humans, Polluted air and water can cause diseases to form in people like Asthma and Gastroenteritis.
The natural sources of air pollution are consisted of volcanoes, forest fires, plants, decaying plants, soil, and oceans while the human-caused gas comes from anthropogenic pollution, photochemical smog, and industrial smog. These types of pollution not only contaminate the area they are in, but also can spread out to other areas due to natural factors such as winds, landscapes, and temperature. Because of the harmful effects of these pollutants, it has resulted in a direct effect of global warming, acid rains, and the depletion of the ozone. Regarding the issues of global warming, “ the change in temperature has become more noticeable and has created a displacement and loss of habitat for some species”(Rinkesh). Although it has yet to affect humanity significantly, it would only be a matter of time before disaster ensues.Acid rains can also be a problem.
Unfortunately with today’s environmental issues people are dealing with several health problems, especially in their immune system. Air pollution, which is one of the major environmental issues, can cause several health risks. Exposure to air pollutants can have a high possibility of resulting in long term effects on people as well as shutting down the immune system. Therefore, the pollution in the air can affect the immune system by weakening it and making it much more vulnerable to foreign invaders, illnesses, harmful bacteria, and viruses. There are several kinds of toxins and pollutants in the air, which contribute to the serious environmental issue of air pollution.
The explanations of this effect are that “Climate change poses unprecedented threats to human health by impacts on food and water security, heat waves and droughts, violent storms, infectious disease, and rising sea levels” (Barrett). It is not just food/water security and natural disasters that pose a threat to human health, but even pollution. Humans are harming themselves because as long as they keep driving cars, fossil fuels will be released into the atmosphere from the exhausts of cars, buses and other transportation vehicles. These fossil fuels pollute the air which causes breathing problems, acid rain, and respiratory diseases on humans. Furthermore, air pollution is a key driver to climate change because it increases temperatures and carbon dioxide rates in the atmosphere.
Not only are human beings affected but also animals and plants. Air pollution might be most noticeable around our congested towns but the thin layer of air that envelops the Earth is polluted at several balances. It is contaminated indoors, locally, regionally, and globally. Smog sagging over cities is the most familiar and obvious form of air pollution. But there are different kinds of pollution some noticeable, some invisible that contribute to global warming.
