Nowadays, pollution is a popular term with everyone in the world and air pollution is one type of pollution. The definition of air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside. A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. There are some main reasons which cause air contamination such as burning of fossil fuels, agricultural activities, exhaust from factories and industries, mining operations, and indoor air pollution. Air pollution always has bad effects on our life. Harmful gases, dust, and smoke enter into the atmosphere and make it difficult for plants, animals and humans to survive. We also can see some examples of the result of air contamination which occurs around us as global warming, acid rain, and depletion of ozone layer. The effects of air pollution are alarming, so governments over the world should have suitable policies of protecting the environment, especially air quality to create a clean world for our generation in the future.

Society is constantly developing, but it cannot be denied that the development brings us a lot of negative environmental issues. Almost all of us have faced environmental pollution, but that problem sometimes is not serious enough for us to actually pay attention. Climate change and the greenhouse effect are always the keywords in most of the environmental pollution topics, but they are usually too big and vague for everyone to understand. To put it down in a simpler way, environmental pollution is what surrounds us every day. Dust from traffic means, noise, rubbish on the streets, or the bad smell comes from rivers is pollution. There are many forms of pollution such as air pollution, soil, water, light or noise pollution. We live in pollution and get used to it so much that we do not even notice it. This not only affects the Earth in general, it also directly affects our health. Emissions are always one of the leading causes of respiratory illness, and climate change is indirectly causing natural disasters everywhere from all over the world. Developed countries are planning a lot remedies to control the seriousness of environmental pollution, but the most important thing is the awareness of each individual. Every one of us can contribute to decrease the level of pollution in our daily activities. If we all have a sense of protection for our environment, we can still develop without destroying the Earth.
