pull your head out of your ass and understand that its more than cars, every time you use spraypaint, every time you use electricity(fossil fuels) or straight up fossil fuels(which is all fucking day with lights, computers, cars, cell phones, subway rides, bus rides, train rides, using paper that was printed by a machine, your fucking camera, your shiny pants that were made with a machine, you fucking textbook that was bound with a machine, the toilet paper that was cut using machines and the trees that were cut down that used to clean the atmosphere up). then include every person in the developing world trying to make a buck for themselves by building a farm on the rainforest, or leaving their taxi running all day so that the airconditioner will keep the clients cool even though its 50 fucking degrees celsius outside, the goddam kid who doesnt know why its bad that he leaves his fridge door open to keep himself cool. hell hes not better off than the ignorant kid who gets a ride to the movies every friday instead of walking. then look at the information being provided to you. not anything from a politician, not anything they tell you in elementary school, or any high school in the states or anyone who is religious. get your information from an unbiased, factual source. then realize theyve been telling you how badly global warming is for the past 30 years. and look at the dumbasses who arent doing anything about it. and realize that you made up your little "fact" just now. then ask yourself why you are such a douchebag. know this. global warming is happening. it is a global climate change, not because of one, and this one is huge and happening fast. know that the extinction of the dinosaurs was because of a huge asteroid hitting the earth, and the extinction of most mammals, bugs, bacteria, birds and plants that is happening right now because of humans is almost a thousand times worse. know that you are a douchebag. but try to understand why.
