In China all district have several spots where you throw wastes. No matter what wastes all goes there: glass, plastic, paper, left over. Chinese people bring their wastes there.
Then scavenger take what is worth something...(plastic, metal...). And the garbagemen will sort out the wastes.
And from time to time they will simply burn the wastes right there on the spot!
Of course this is a shame and has to change.
It produces a lot of toxic smoke that is releazed directly into the atmosphere!
Furthermore inhabitants will breath this smoke. But it doesn't seem to worry anyone yet...
