I just learnt about the word plasticarian from WorldWideWords. It refers to someone who tries to live without using plastic. Of course, it is a blend of plastic and the -arian ending. What is a bit unusual about it is that -arian usually indicates something positive: a vegetarian loves vegetables, and a humanitarian loves humans, but a plasticarian hates plastics.
Regardless of how the word is formed, we need a few more plasticarians in Brunei. Plastic bags and bottles are all over the place, not just in Kampung Ayer and in the Brunei River, but even in the forests. And while it is true that it almost impossible nowadays to live without plastic, it would be helpful if a few more people reduced the amount they used, or at least did not discard their rubbish so carelessly.
