Seven billion of the world’s population annually produce 300 billion PET (polyethene terephthalate) bottles and eventually dump 80 per cent of it into the environment. And Sri Lanka with a mere 22 million population is the world’s fifth largest sea polluter with its plastic disposal to the ocean. ‘International Business Times’, a US-based website reported a few years ago that Sri Lanka dumps 1.6 metric tons of plastic and polythene annually to the Indian Ocean.
