Since the construction of roads has not kept pace with the number of vehicles sold, it has lead to congestion on the road.
There are four major pollutants that come from cars: combine in sunlight, they produce ozone.
High in the atmosphere, ozone protects us from the sun’s ultraviolet rays.
The percentage of air pollution caused by cars is higher in urban areas and higher still near major highways. government has imposed tougher emissions standards, and consumers want better efficiency.
Fortunately, better fuels and new technologies in cars help. According to the EPA, today’s cars emit 75 to 90 percent less pollution per mile driven than cars made in 1970 did.
According to the EPA, motor vehicles collectively cause 75 percent of carbon monoxide pollution in the U. The Environmental Defense Fund (EDF) estimates that on-road vehicles cause one-third of the air pollution that produces smog in the U. has 30 percent of the world's automobiles, yet it contributes about half of the world's emissions from cars.
S., and transportation causes 27 percent of greenhouse gas emissions. The United States was long considered the world’s biggest polluter in terms of carbon dioxide and other greenhouses gases, but by 2008, the United Nations had reported that China had moved into the top spot.You see it every time that smoke billows from your car's exhaust pipe, so there's no denying that vehicles are major contributors to air pollution.Air pollution refers to the presence of foreign substances in the air that don’t belong there, or excessive amounts of certain impurities that wouldn't harm us otherwise. Gasoline fumes escape into the air even when we pump gasoline into our fuel tanks.When holes in the atmosphere's ozone layer allows ozone to come closer to Earth, it contributes to smog and causes respiratory problems.Air pollutants emitted from cars are believed to cause cancer and contribute to such problems as asthma, heart disease, birth defects and eye irritation.Hybrid cars, electric cars and alternative fuels will continue to help, but the sheer number of people -- and cars -- on the roads offset those improvements. If you have to get out of the house, combine trips for efficiency.Walk, bike, carpool or use public transportation if you can.Comfortable: Cars are epitomes of comfort with plush seats and climate control.With the arrival of the automatic transmission, driving the car has become easier for the people.Cars have become the heart and soul of transportation since their invention by Henry Ford.People are influenced by their style and performance as they wade through the streets and on the highways at top speeds.
