Car,Should be Banned in Cities?

Car becomes one of important thing in human life. Many people can waste their money to buy a new released car. Car becomes prestige thing. in my opinion car should be banned in cities because some reasons.
Firstly, car can produce some dangerous material like SO2, CO2, NO, etc. those materials are very dangerous. For example, NO can compound with Haemoglobin (important substance in blood) faster than O2, it can make blood lack of O2 and can causes some serious diseases. SO2 and NO2, if those materials compound with vapour in the air, it can be a compound with low PH or acidic compound. If those acidic compound fall on to surface of the earth, it can make rain acid which can break some things
Secondly, car is wasted, as we know, now days the price of oil is increasing, now the price of oil is USD 106.60 per barrel. The more car, the more money must we waste to buy oil
Then, car can make a distance between rich man and poor man. Rich man can go everywhere by his car, so they rarely communicate with others
Then, car always make traffic jam, many car produced but there is a few car out, that caused populated of car in cities. so traffic jam will happen in cities .
Beside that car also has some good side. Car can bring something which people difficult to bring. Car can help us to distribute something in big number, or bring something in big size with a long distance
In conclusion, although car can help human, some reason can tell us that car gives many disadvantages for people in cities. So I thing car should be banned in cities. It’s better to use bicycle to go everywhere, it healthier, cheaper, and more enjoyable than go by car
