text: Recently, I've heard about all the well known car dealers pushing hybrid cars and trying to design a enviornment friendly vehicle. But in reality, the only big step to helping our planet is to reduce cars overall. Studies shown that green house gases are "... up to 50 percent in some car-intensive areas in the United States". Not only is the green house gas rate going up, but pollution, carbon emissons, and smog are as well. In Paris, France they had to ban driving for a couple of days as the pollution produced smog. "[Last] week Paris had 147 micrograms of particulate matter (PM) per cubic meter compared with 114 in Brussels and 79.7 in London...". The numbers keep rising in Europe and the USA. Picture what our enviorment is going to be like in 20 years if we keep this pace up. Without these machienes we could reduce the number of micrograms, produce the harmful gases from affecting the enviroment, and stop polluting the air we breathe.
