For more than a century, cars and sleeper truck have been a dependable mode of transportation, transforming American travel. They cleared the way for the growth of suburbs and made it possible for tourists to go coast to coast. Many Americans find it difficult to picture a life without a car. But the ecology has paid a price for all this movement.
34% of the nitrogen dioxide emitted into the atmosphere comes from motor vehicles. In addition, they produce 33% of the dioxide, 10% of the particulate matter, and 51% of the carbon monoxide. Acid rain is brought on by nitrogen dioxide, which also encourages the development of algae. Particulate, commonly known as soot, contributes to haze and ground water pollution. Carbon monoxide is a dangerous gas that can result in death in high concentrations and migraines, breathlessness, and vomiting at lower concentrations.
Water supplies are contaminated by cars in a number of ways. One is through discharge from brake dust, oil, deicing agents, and vehicle fluids. Another is through gas station pumps that leak. Ground water pollution is also a result of improper motor oil disposal.
Once an automobile is not in use, its environmental effect continues. Every year, more than 10 million automobiles are discarded. In the region of 25% of these automobiles, recycling fails, and they wind up in landfills. Additionally, some hundred million tires are discarded annually.
With tens of billions of vehicles on the road, they occupy an area larger than the state of Massachusetts, at more than 13,000 square miles. Urban roads extend across a further area of around 4,000 km.
Furthermore, a sizable portion of the fossil fuel supply is used by cars. While utilizing 26% of the world’s oil, the United States only produces 10% of it. 43 percent of the petroleum used annually is used by light vehicles and autos.
In the US, there are around 250 million automobiles. They are mostly responsible for the noise in big cities.
