While many people complain about climate change, few people actually take meaningful action to help save the earth. But helping the environment does not have to cost much time or money. Simple things, like reducing plastic bag usage, can do a lot to help.

Hout Siekhuoy, 21, who studied environmental issues in the United States, said that we should reject plastic bags at stores when we do not really need them.

For instance, when we buy two books and one pen from a store, we can put them into a school bag instead of asking for a plastic bag from the seller.

We can also bring bamboo or plastic baskets instead of asking for plastic bag from the seller because they can be reused.

If we do need plastic bags when we buy something, we can clean them afterward and reuse them when we go shopping next time.
