The car has been one of the most useful inventions humans ever made. It profited man very much. It brought him to places faster and cooler, without tiring his legs too much. Some men even consider their cars their best friends because it has served them for so many years. It is now considered many years since the first car was ever invented. It has done us much good; however, it has not done Mother Nature much good. While men are profiting, mother Earth is even suffering more and more.

One of the many harms cars man and his cars have brought to this world is the air they booth breath out; men, their carbon dioxide, and cars their smothering smoke. People now are starting to feel the effects on Mother Nature as she begins to decay. The ozone layer is thinning and the sun is about to burn the surface of the Earth.

It is not too late for man to make cars that reconciles with Nature; cars that are ozone friendly. Men are now developing new fuels for these cars. These fuels are bio-diesels who happen to be as friendly to Mother Nature as it is with cars.
