The amount of smog riveled to the smog capital of the world Beijing, China. That was only five days of car smog. If we keep this up, the  first the sky will turn black and then it will fall and world will end! Hopefully nobody wants the world to end because of smog. To reduce the amount of smog and pollution caused by cars we can all reduce the usege of our cars. Therfore, the limiting of cars can significantly reduce pollution.
