Life Would Be Healthier Using Pollution-Free Automobiles
All this hocus-pocus regarding air pollution might possibly be incomprehensible to an individual living in Montana. However when you live downtown and you can practically touch the air, never mind see it, and to breathe deeply can be a challenge, things are a little different. Air pollution is rife around the world, and even regions that don't generate their own get it blown in from elsewhere.
The air is filled with things that are bad for people, like carbon monoxide, sulfur dioxide, nitrates, lead, ozone, secondhand tobacco smoke and particulate matter. Particulate matter comes in many different forms, for example vehicle emissions, road dust, power generation, and many types of industrial pollution. They also can be from volcano's, mold, forest fires, pollen's, and many other sources that make the environment rather dirty. All of these particles come in various sizes, composition and origin, and one of the most significant components is automobile emissions. The greatest contributors to the ever-worsening air pollution are cities packed with vehicles, and as you would expect the biggest cities are definitely the worst.
Carbon monoxide gas is a primary part of air pollution, but it's not easy to detect, being without having color or odor. Cigarette smoking and gasoline-powered vehicles are definitely the main sources. It is harmful to the body, since it decreases the level of oxygen, and high enough levels are fatal. Respiratory ailments are being caused by carbon monoxide, even being absorbed by the body in small amounts over a long period of time. Many of the world's health problems are due to ingesting carbon monoxide. There are plenty of reports proving how negative the effects are with air pollutants, especially from cars, but also factories.
It's been shown that the presence of the many pollutants changes between cities. A study over 5 years with 5,000 adult participants concluded that exposure to air pollutants a result of traffic contributed to a higher mortality rate. People living near to a busy road have an increased probability of dying from a cardiovascular disease, just like a heart attack. People living in the most polluted cities in the US will have their life expectancy reduced by two to three years because of the pollution in the air. Professionals have arrived at the conclusion that dying from a cardiovascular event is more likely for people who have been exposed to very high levels of particle pollution, even if only over short terms.
The increase in cardiovascular plus pulmonary disorders as causes for hospital admission is proportional to how much greater the concentration of particle pollution is in an area. Life expectancy will be reduced by several years due to living in places where the particle pollution is elevated. When these facts are examined, the destiny for the people in America is rather grim, unless things are changed. There must be a better way to control the amount of pollution from vehicles, or the future will be even worse than the present.
