Say “ No” to Plastic Bags
Since June 1st, 2008, plastic bags are no longer provided for free in the supermarkets. Different people have different opinions on this matter.
As far as I am concerned, the government is taking steps to protect our living environment. It’s true that plastic bags make people’s shopping more convenient. However, most people just throw them away after using them, and don’t know how to deal with them. What’s more, it will take a long time for plastic bags to break down. As a result, they can cause serious pollution and do great harm to our surroundings, then to people’s health.
Personally speaking, I fully agree with this policy. After all, it is good for our environment. And we could use bags made of paper or cloth instead of plastic bags when shopping.
