First, the pace of industrialization and urbanization accelerated; the increasing population pressure on increasingly heavy for water resources in the territory. Increasing population and water resources increasingly scarce and heavily polluted. Source sewage and industrial waste discharged into waterways as sources of drinking water and irrigation. Sources used for drinking water is contaminated directly, also used to irrigate the trees penetrate, food, feed into contact, causing indirect harm to humans. Another part of waste water toxic pollutants can seep into the soil directly through the groundwater to contaminate our water. Water environment in many urban areas, industrial zones, villages increasingly contaminated by waste gas, solid due to no work and waste disposal equipment synchronization.
Second, the air is polluted by habitat. More than 50% of the world population, mostly in developing countries, to use coal, wood and straw for cooking. This is the cause of 3 million deaths annually worldwide and 4% of cases of illness. The cooking takes place in a cramped area, no exhaust system. Additionally during the operation of the transport emissions into the air large amounts of various kinds of smoke, toxic gases such as CO, CO2, hydrocarbons, NO2, SO2, black smoke, lead and other grains. Depending on the type of engine and fuel that the volume of hazardous waste different proportion in the exhaust gas. These substances when reacted with sunlight to form new compounds, eg ozone, toxic air near the ground is very toxic.
Finally, it is worth noting that noise pollution. Noise is a common form of pollution in urban areas. In the generated noise sources in urban areas, the means of transportation plays a major role: Noise from the engine, so the exhaust. The noise caused by vibration of vehicle parts. This noise level depends on the technical condition of vehicles. Noise caused by closing the car, so the car horn, so braking, so the interaction between tire and road surface, much as both women's screams startled car caused panic for pedestrians etc ...
I think the main the right to have reasonable policies to minimize environmental pollution
