Chapter 6 - Environment Damage
It took over 200 million years for the oil beneath the earth's surface to form. In the past 200 years, we have already used half of that reserve. If current rates of consumption continue, the world's remaining oil would be used up in 40 years.
Right now, two-thirds of the oil used around the world powers transportation vehicles, and half goes to passenger cars and light trucks. Being conscious of our fuel use will help to conserve resources for future generations.
Transportation involves the combustion of fossil fuels to produce energy translated into motion. Pollution is created from incomplete carbon reactions, unburned hydrocarbons or other elements present in the fuel or air during combustion.
These processes produce pollutants of various species, including carbon monoxide, soot, various gaseous and liquid vapor hydrocarbons, oxides of sulphur and nitrogen, sulphate and nitrate particulates, ash and lead.
These primary pollutants can, in turn, react in the atmosphere to form ozone, secondary particulates, and other damaging secondary pollutants. Combustion also produces carbon dioxide, the primary greenhouse gas.
These environmental concerns about the country's transportation habits have been studied extensively. The tailpipe emissions from cars and trucks account for almost a third of the air pollution in the United States.
Although smog is produced by many factors, including sunlight, temperatures, winds and "basin" effects the air pollution caused by transportation is a major contributor. In their Sprawl Report 2001, the Sierra Club graded the car and truck smog in America's 50 largest cities using data from the EPA.
