Remember the subsidy time, each time hear the garbage cart is we in our childhood, rubbish together pulling the bucket to the rubbish dump. The rubbish truck is rarely full, there is nothing to eat but full. At that time there was no "plastic waste" as plastic was very rare and left for reuse. Street is deserted, but poor, full of bicycles and pedestrians, cars are painted. Only a few, the environment can be said to be clean.
And how does our environment change now?
