we use lots of plastic bags everytime we go grocery shopping, but we don't throw it away after, we fold it properly and keep it in the cupboard and use repeatedly.. the problem is, some people just throw plastic bags out on the streets, and not only plastics mind you, but other rubbish too.. it's sad to see too many rubbish everytime we go to the beach just lying around when you see a number of rubbish bins spread all around the beach, they're just too lazy to look for one and dump their rubbish properly.. discipline is the key..
