People are still using plastic bags, especially in the food stalls and wet markets.

Efforts to save the Earth must be accompanied by an educational campaign nationwide.

Take Hong Kong for instance. In addition to controlling plastic bag usage, it has embarked on a campaign to help the public understand the repercussions of not using fewer plastic bags.

We can do likewise and help the older generation understand why we need to curb the use of plastic bags and what the causes of global warming are.

One suggestion: Provide pointers on global warming in utility bills so that people will take notice and read it. It should be done in the four major languages.
