Why a topic on cars??? Well cars produce one of the largest amounts of airpollution known to man, smelly combustion engines that eat up all that lovely oxygen that our blood needs and replaces it with a mixture of carbon dioxide and what was once lead. Not so much lead now adays, but there is still unquestionable damage on the respiratory system. It's even known for Asthma suffers to die just from trying to cross the road at a busy junction because of the pollution that the cars create. Cars are also lower the amount of oil in the world, even though a car doesn't necessarily need to run on petrol and oil. Petroleum prices are hiked by a monopoly that is controlled, and occasionally they notice the mergence of an immenent collapse in their market. Some Economists will spell out gloom if those companies faulter, but thats only because they've got shares in them. (they play on the guilt of people buying to help them out) In truth Oil, is something that shouldn't be used excessively, it's like hiking in the mountains with enough rations for 3 days and your 8 days away from the nearest food source. There are developments on the horizon for new powersources of perpetual power systems, that only need a kickstart to keep them kicking over, these will eventually be encompassed into electric-car designs that the oil companies would love to veto. This is where the new market begins and the old market is going to have to mak way for the ecological factors, and of course the FINES for not cleaning up.
