Noise pollution is considered as the environmental pollution caused in the environment by the excess level of noise through many sources. Noise pollution is also known as the noise disturbance. Excessive noise is harmful to the health and cause imbalance to the human or animal life. It has been a massive environmental issue in India which needs a proper attention to be solved however it is less dangerous than the water, air and soil pollution. Outdoor noise is hugely caused by the sources like machines, transportation systems, poor urban planning (construction of side-by-side industrial and residential buildings), etc. Indoor noise sources are household machines, building activities, loud music, etc... The most common impairment caused by the noise pollution is the permanent hearing loss due to ear drum damage.

I like living in the countryside because of some reasons. Environmentally speaking, it is a peaceful place. The air is fresh. The space is quiet. We can enjoy healthy natural conditions without worrying much about environmental pollution.

As for social security, the countryside is a safer place than a city. While urban security situation is always complicated with all kinds of crimes, rural areas are much more secure because most of countrymen are friendly and ready to help one another.

Moreover, rural life is also easier that in cities. People in cities are easy to get stressed because of pollution, job pressures, competitions, etc ... On the contrary, those bad things are very rare in the countryside. To sum up, except income matters, the countryside is a better residence than cities.

Perilous pollutants may contain various types of impurities including harmful chemicals, dissolved gases, suspended matters, dissolved minerals, and even microbes. All the contaminants reduce the level of dissolved oxygen in the water and affecting the lives of animals and human beings to a great extent. Dissolved oxygen is the oxygen present in water required by the aquatic system to continue the lives of plants and animals. However biochemical oxygen is the demanded oxygen by the aerobic micro-organisms to oxidize organic matters of wastes. Water pollution is caused by two means, one is natural water pollution ( due to the leaching of rocks, decay of organic matters, decay of dead matters, silting, soil erosion, etc ) and another one is man-made water pollution ( due to the deforestation, set up of industries near large water bodies, high level emission of industrial wastes, domestic sewage, synthetic chemicals, radio-active wastes, fertilizers, insecticides, pesticides etc )
