text: Many people now a days worry a lot about the enivornment specifically the negative things that have been done to it like how green house gasses are destroying the ozone layer. It makes the earth more exposed to the sun's radiation and causing a negative chain of events like the polar ice caps melting. According to source one "In Germen suburb life goes on without cars" its revealed that cars account for twelve percent of green house gasses in Europe and fifty percent of green house gasses in the United states. This is especially problematic in large dense cities where car green house gasses add to the pollution by mixing in with other green house gasses from other parts of these cities. In source two "Paris bans driving due to smog", cars are the cause of the terrible smog problem Paris is facing which causes many driving problems. If we stop using cars we immediately cut down on how much green house gas gets released into the ozone layer. It would not only be good for us but good for the enviornment as well.
