text: Don't get me wrong I love driving and all but it's effecting our ecosystem. Just think if one day out of every week we rode our bikes, or we car pooled, or we took the bus think of how much smog would go away. In source 2 it talks about how they enforced a partial driving ban to clear the air of the global city. On Monday motorist with even-numbered licence plates were ordered to leave there cars at home same went for odd-numbered licence plates the following day. With in five days sixty pecent of the smog was cleared. And they only did it for five days, imagine if every city in the world did this once a month. In source one it states that passenger cars are responsible fro twelve percent of green house gas emisssions in Europe, and up to fifty percent in some parts of the United States. In source one it also talks about a city in Germany named Vauban. Vauban is a city that has banned cars. There is a main thoroughfare , where the tram runs to downtown Freiburg, and and a ffew streets on the edge of the community but ther e are only two places to park-large garadges on the outside of town. And it cost 40,000 dollars along witha home. If we had cities like this here in the U.S. it would be so much better and there wouldnt be so much pollution.
