Transportation

Transportation and environmental issues are opposite in nature since transportation deliver socio-economic benefits are great, but at the same time impactingenvironmental transportation system. On one side, supporting transport activities growing demand for passenger and cargo movement, while on the other, transportation activities associated with increasing levels of external environment. This has reached the point where transport is the dominant source of the pollution emission and multiple effects on the environment Complexity of the problem that has led to much controversy in the policy environment and the role of transport. The transport sector is often subsidized by the public sector, particularly through the construction and maintenance of road infrastructure which tend to be independent of the access. Sometimes, the public interest in the mode of transport, terminal and infrastructure can be odd with environmental issues. If the owner and the same regulator (different branches of government), then there is a risk that the rules will not be effectively observed. It can also lead to another extreme where compliance would lead to an inefficient transportation system with the cost of subsidies.
The environmental impact of vehicle pollution burning fossil fuels such as natural gas and gasoline used for transportation the way we produce harmful chemicals, among them carbon dioxide, a greenhouse gas, which is a major pollutant and contributor to global warming. Over 150 years ago, cars, airplanes and power plants have been producing carbon dioxide into the atmosphere enough to raise a higher level than ever before. Single car emissions are generally low, but added to the emissions from the millions of vehicles per day used to create a huge impact on the environment and air quality. Car pollution reaching water pollution, noise pollution, air pollution to global warming, to give effect to human health. On-road motor vehicles not only release carbon dioxide but
