@Mor - Household waste collection is a real problem in developing nations, and especially, I'd imagine in island nations. I know that in many places in Africa, you can't go anywhere without seeing massive amounts of plastic bags littering the street and the countryside.
While placing rubbish bins and organizing collections is a good idea, frankly I think this is just a temporary solution, and we should be thinking of it this way here as well.
More permanent solutions would be to start a recycling collection, and just making everything biodegradable and reusable. This would be especially useful in poor countries where an extra source of compost or another way of getting cheap materials should be welcome.
