Another cause of environmental pollution is the lack of responsibility of businesses. The most profitable multi-profit, not least business scope cascade, return the environmental pollution score. In addition, policies that are not well organized in the state's management and protection environment have also been approached for the next environment. Vietnam lacks strict environmental protection policies and regulations and makes investments vulnerable to the "trap": becoming more polluting industries. For example, the steel rolling industry consumes a lot of resources, such as land, water and energy, which pose environmental hazards. Out, amount of car to be shared in a few days at least you can not less into the preset gas beats.

I'm living in a very crowded area in the city. There are several problems with my local environment and noise pollution is the biggest one.

Noise pollution is the pollution caused by the high and unsafe level of noise in the environment causes lots of health disorders to human beings, animals and plants. Common problems caused by the noise pollution are stress-related illnesses, anxiety, communication problems, speech interference, hearing loss, lost productivity, sleep disruption, fatigue, headache, irritability, nervousness, weakness, reduce sensitivity to sound which our ear receive to maintain body rhythm, etc. It causes gradual impairment to the hearing ability over a long period of time. Continuous exposure to high-level sound causes permanent damage to the eardrum.

There are many preventive measures of the noise pollution, some are like promoting soundproof rooms construction in the industries, industries and factories should be away from the residential building, repairing of motorbikes having damaged exhaust pipes, ban of noisy vehicles, airports, bus, railway stations, and other transport terminals should be far from the living places, declaring silence zones near educational institutes and hospitals, allowing more vegetation along with roads and residential areas in order to reduce noise pollution by absorbing sound.
