Topic : Air Pollution Air pollution is the most major problem nowadays that happened in the world.. it caused by harmful gases such as carbon dioxide, nitrogen dioxide, carbon monoxide and very small particles of carbon. Most of the pollution is caused by factories, vehicles and livestock. Today air pollution has become dangerous to humans. Heavy air pollution may cause breathing problems such as asthma or other health problems. The effect of the air pollution is the global climate change, particularly, global warming. As the temperatures around the world are increasing , the sea levels start increasing, and icebergs are gradually melting. As a consequence, numerous species have lost their place. One more effect is acid rains which take place when fossil fuels are burnt. During the rain nitrogen oxides and sulfur oxides emitted into the atmosphere combine with water drops. Those, in their turn, become acidic and fall on the ground. Acid rain inflicts damage on humans. Air pollution often leads to various respiratory diseases among humans such as bronchitis as well as more dangerous ones like Cancer. Millions of people die annually due to direct or indirect effects of air pollution. There are many things that people do to cause air pollution but there is also many ways that you can prevent it. We must work together to reduce pollution so that the future generations can live in a healthy.
