Cars and Global Warming

One of the most eye-opening conclusions of reports is that the vehicles we choose today will affect our lives for time to come. Astonishingly, the largest category of current on the road polluters is the small car. We ask ourselves why? Well, simply because there are so many of them on the road. Cars in and light trucks our nations are a huge supply of global warming pollution. United States automobiles emit more than 333 million tons of carbon dioxide (CO2) per year, which is more than 1/5 of the nation's total CO2 emissions.
Compared with the rest of the planet, American automobiles emissions are excessively high. With only five percent of the world's population and thirty percent of the world's automobiles, the United States put in forty eight percent of the world's automotive CO2 emissions.
Any true effort to battle global warming has to include cutting automobile emissions. Acting now is crucial to slowing global warming and reducing air pollution.
Americans don't all have to drive hybrids to make a change in our nation. And, while we support everyone to use different forms of transportation whenever it is possible, the certainty is that cars are a big part of our American ways of life.

We should be thinking to:
• Put public pressure on the automobile industry to maintain a comprehensive national global warming policy.
• Educate vehicle owners and drivers on what they can do to decrease emissions.
• Explore ways we Americans can do our part to progress fuel efficiency and cut global warming pollution from America's automobiles.
So, if we all did our part to decrease automobile emissions and if all of us purchased the most fuel efficient vehicles that met our needs, and if all of us found ways to drive a less, if all of us did our best to keep our vehicles maintained, and if all of us contributed in prioritizing global warming as a issue in our daily lives, we would considerably decrease global warming pollution from America's vehicles.

The Main Cause for Global Warming

We humans who think of ourselves as the most intelligent things on this planet are intentionally or unintentionally destroying our own surroundings. One of the chief causes for global warming can be accredited to the behaviors of humans. It took more than twenty years for the world to finally accept that we humans are causing global warming with the emission of greenhouse gases which include carbon dioxide, methane, nitrogen oxide etc. the gases have formed an effect of green house on the earth’s exterior which prevents the reflection of the sun’s rays and therefore causes the boost in temperature. The radical boost in the emission of carbon dioxide in the last 30 years caused by burning fossil fuels has been recognized as the major reason for the change of temperature in the atmosphere.



Carbon dioxide concentration in the air has amplified because of the emissions from power plants, airplanes, cars, industries etc. one more reason for it is deforestation. Forests have been reduced making way for cultivation, industries and cities. The vegetation was natural regulators of carbon dioxide that controlled its level’s in the atmosphere. Eighty percent or more of the worldwide energy claim is currently supplied by the fossil fuels oil, coal or gas. It will be unfeasible to find alternative sources, which could restore fossil fuels in the short or medium term. The energy demand is just too high.



Another subject is the non-renewable traits of fossil fuels. It took our planet millions of years to produce these resources, while we will have used them up in about the next few decades. Alone the lessening supply will not make it possible to carry on as usual for a longer time.
