If there are 9 million bicycles in Beijing, why is the place so polluted?

Question

If there are 9 million bicycles in Beijing, why is the place so polluted?

Answer 1

Because the number of cars in Beijing has doubled since 1995.  

Answer 2

mainly because of factories alot of stuff are from china.

Answer 3

Mainly because of coal fired power stations and factories, but there are also milions of cars too.

Answer 4

Not only because of cars and factories but lack of maintenence.  Automobiles are still fairly new there.  In North America, you see oil lube maintenence stations every few blocks, but in China they are very very rare.  Eventually they will catch on and build them because it's a very good business to make $$.  And hopefully control their car pollution.

Factories, sweat shops, etc...

Answer 11

It's not only cars that pollute the air. There are factories and buildings that dump tons of carbon dioxide into the air, especially with coal (which is the dirtiest and cheapest source of energy) being the number one source of energy for the country. 9 million bicycles don't mean anything. People still ride cars, buses, etc (the traffic in Beijing is ridiculous).

Don't forget China has a population of 1.3 billion people.

Answer 12

factories making all that stuff

it would be ten times worse if they had cars! lol
