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.
There are so many fuel efficient cars are also available now.
Due to the presence of a large number of options, customers can pick and chose their favorite cars.
In short, they have become the part and parcels of the life however like any product they too have their shortcoming.
So, let’s find out their positive and negative effects on people.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.Emissions from cars increase the levels of carbon dioxide and other greenhouse gases in the atmosphere.At normal levels, greenhouse gases keep some of the sun’s heat in the atmosphere and help warm Earth.That said, many scientists believe that burning fossil fuels such as gasoline causes greenhouse gas levels to spike, leading to global warming.Scientists use sophisticated instruments to measure concentrations of harmful substances in the air, but it’s tough to say exactly what percentage of air pollution comes from cars.They can travel at extremely fast speed and are also nimble in the busy city traffic.Apart from cutting the travel time, cars also express the individuality of their owners.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.
