Today, motor vehicles are responsible for nearly one half of smog and emitting more toxic gases in the air such as nitrogen oxide. Almost half of the nation’s greenhouse gases come from auto mobiles they now account for seventy five percent of carbon dioxide emissions nationwide. Emissions from cars increase the levels of carbon dioxide (CO2) and other greenhouse gases in the atmosphere. At normal levels, greenhouse gases keep some of the heat in the atmosphere and help warm the Earth. This is caused by the cars burning greenhouse gases which makes carbon dioxide that causes clement change. Vehicle emissions can affect the environment in several ways. Cars emit greenhouse gasses, such as carbon dioxide, which contribute to global warming. Some air pollutants and particulate matter from cars can be deposited on soil and surface waters where they enter the food chain and affect animals and humans all the same. Auto mobiles also produce ground pollution as well if there is an oil leak from a car’s engine or from a car crash, it can make its way to the ground and affect the ecosystem drastically by killing plants poisoning animals and infecting the ground with all the pollutants from cars. Some places are getting overrun by smog which is smoke clouds made by pollution such as Beijing in China and even the city of lights Paris France. We know China is slaking on the situation but Paris made public transit free to try and tackle this problem. Smog is affecting a lot of places commonly known to the general public like San Francisco and like stated above Paris smog is harmful to people’s health and these places need to fix the problem. Most city’s don’t do this and because of their popularity with the public they should be the first places to try and fix this problem.
