One environmental law I’d like to talk about is the ban on free plastic bags¹ in shops, which was introduced in China several years ago. Under this policy, supermarkets and many other retailers are not allowed to² give customers thin plastic bags for free. Instead, shoppers need to pay a small fee for them or, preferably, bring their own reusable bags. I first learned about³ this law when I was in primary school. My mother used to collect a large number of plastic bags after grocery shopping, but one day she started taking cloth bags with her. She explained that the government had introduced a new rule to reduce plastic waste. Later, I also saw posters about the policy in supermarkets and learned more about plastic pollution in school. I think almost everyone benefits from this law. Ordinary people can enjoy cleaner streets, parks, and rivers, while future generations will face less environmental damage. Wildlife benefits as well⁴, because animals can mistake plastic bags for food or become trapped in them. In addition, the law encourages businesses and consumers to develop more sustainable habits. Personally, I strongly support this law. Although paying for a bag may seem slightly inconvenient at first, it makes people pause and consider whether⁵ they really need one. In my view, small changes in daily behaviour can make a meaningful difference when millions of people take part. I believe this law is practical, easy to understand, and an important step towards⁶ a greener lifestyle.
