'recycling lotto' scheme could boost green lifestyle

Now here's an interesting dilemma for Christians -at least some. "The National Consumer Council (NCC) aims to boost recycling by staging a prize draw using recycled products as the ticket. A similar scheme in Norway boosted the number of people who recycled drink cartons from 30 per cent to 70 per cent."
The dilemma being the old one of not supporting lotteries because they offer to make money out of money by a game of chance where ones money is not earned and in a society where gambling is a source of false hope and ruined lives.
But wait on -there's no stake in this game and the aim is to make a virtuous action more likely. Okay so it's not true virtue or slavation but it would result in a better environment: I'm happy with that but I wonder how other Christian opinion might run with it. I think that it would be worth pointing out that the using of less altruistic drives in order to produce benefits for the common good is not new and is accepted as a potential ally in social welfare in much Christian thought [though not uncritically in the case of markets, for example]. It is also arguable that Jesus did it in appealing to our 'selfish' desire for forgiveness and salvation to motivate us to accept God's grace and to follow him. It's sometimes called enlightened self-interest and I can't see how [a] we can get away wihout it in some human life or [b] that it is necessarily and in itself wrong. The issue is how we weigh it agaisnt the needs and demands of others and of God.
