A lot of people are worried about the environment and call for more people to protect our earth. A ban(禁令) on the use, sale and production of single - use non - degradable(不可降解的) plastic products was carried out across Hainan Province. It's the second province in China to ban these products.
The products include plastic bags, meal boxes, bowls and drinking cups. The province also made a list of products that people can use instead, such as cloth bags and baskets made of bamboo.
Many people have mixed feelings about the ban. "Caring for the environment is good for all of us, but my business costs will grow. The cost of the biodegradable(可生物降解的) plastic bags I prepare for my customers every day will be very high. I hope the bags will become cheaper in the near future," Wang Ling, a vegetable seller, said.
Hainan has 19 companies that produce biodegradable plastic products. Another 42 companies in other provinces are helping Hainan by providing fully biodegradable plastic products.
Besides banning single - use non - degradable plastic products, Hainan has done many other things to improve its environment in recent years...
