If we reuse and recycle the plastic bags, we dont need to buy a new one. Therefore, The shops will purchase less from the Producer (製造商). The 生意 of the producer drops and they will produce less plastic bag!! And this leads to 環保....
If each body can save a plastic bag a day, 7.5 million of plastic bags can be saved in a day...!!!! Understand?
Let's start to save the earth together now!!!!
