“Charging people for plastic bags may be a good way．It may make people realize the harm of plastic bags and the importance of protecting the environment．”

However，some people showed different opinions．“Plastic bags are convenient，and I am not used to buying things without them．” a 35-year-old taxi driver said．“Of course I do not want to pay money for plastic bags．”
