With 600 million motor vehicles on the road releasing 350 million metric tons of carbon emissions into the air, the problem of global warming is increasing rapidly. Each and every time carbon dioxide is released into the air, the health of the environment and people are at stake.
Carbon emissions released by motor vehicles are one of the primary causes of global warming.
The statistics regarding the emissions of these motor vehicles are scary. On the average, a car that travels 550 miles a week releases 31,460 pounds of carbon dioxide into the air each year. Burning one gallon of gas generates 22 pounds of carbon dioxide. In the quest to save the environment and cut down on traffic, congestion and smog, electric mass transit systems are making their way across large cities in the United States and Europe. For example, in Seattle, a poet named Grant Cogswell and a cabdriver named Dick Falkenbury proposed a citywide monorail system.
