Imagine how much healthier a human being would be if there weren’t somuch pollution in the air. Vehicle pollution has been said to be one of the highest factors of the air being polluted. If there is a way to eliminate the vehicle pollution, the lives of citizens would become healthier. Air pollution emitted from transportation contributes to smog, and to poor air quality, which has negative impacts on the health and welfare of U.S. citizens. Pollutants that contribute to poor air quality include particulate matter (PM), nitrogen oxides (NOx), and volatile organic compounds (VOCs).(United States Environmental Protection Agency Agency) Smog coming from the vehicles can create a significant amount of health issues. It could even create the density of the air to change, causing you to not be able to see past the smog. Smog could be harmful to children and senior adults. Some of the gases that come from the cars are greenhouse gases. Motor vehicles also emit pollutants, such as carbon dioxide, that contribute to global climate change. In fact, cars and trucks account for over one-fifth of the United States’ total global warming pollution; transportation, which includes freight, trains, and airplanes, accounts for around thirty percent of all heat-trapping gas emissions. (Union of Concerned Scientists) Schreiber 2 There are ways to reduce the pollution in the air by vehicles. Driving less would cut most of the emissions being let out into the atmosphere. Riding a bike or walking is way to get somewhere without letting out gasses into the air. Vehicles maintenance; such as air-filter changes, changing oil regularly, and spark plug replacements; can lengthen the life of your car as well as improve fuel economy and minimize emissions. Hybrid vehicles could help reduce emissions causing pollution and reduce the dependence of oil for transportation. This car features a small fuel-efficient gas engine combined with an electric motor that assists the engine when accelerating. The motor is powered by batteries that will recharge automatically while you drive allowing you to drive for longer periods of time and less oil consuming. According to Pollution Issues, “The key to burning less fuel is making cars and trucks more efficient and putting that efficiency to work in improving fuel economy. The U.S. federal government sets a fuel-economy standard for all passenger vehicles. However, these standards have remained mostly constant for the past decade. In addition, sales of lower-fuel-economy light trucks, such as SUVs, pickups, and minivans, have increased dramatically. As a result, on average, the U.S. passenger-vehicle fleet actually travels less distance on a gallon of gas than it did twenty years ago. This has led to an increase in heat-trapping gas emissions from cars and trucks and to an increase in smog-forming and toxic emissions resulting from the production and transportation of gasoline to the fuel pump.” Gas prices have went up massively compared to what it was when cars were first made. Now that you get less miles per gallon, you have to refuel your car much more often which is causing more emissions to the air. Advanced technologies such as the hybrid cars Schreiber 3that are ran off of batteries would be more efficient on mileage and not using the gasoline at the pump.
