The big one is the unfiltered burning of fossil fuels. The smoke form cars and other gasoline powered and petroleum powered engines creates a very heavy smog in densely populated areas. China also dumps billions of gallons of wastewater into their rivers.
The cause of Beijing's rampant air pollution is from constantly working factories and millions of cars on the roads. Beijing has some of the worst air pollution in the world.
The Olympics caused all- sorts of problems for Beijing many due to the amount of people there as there were problems like sewage in the streets as the sewers over flowed and loads of rubbish was dropped in the streets and also the shear weight of traffic caused many pollution warnings! I.J.P :)
air pollution is an impact on the Beijing Olympics
