The New Puritan Cause!
"A plastic-bag ban does, however, accomplish many other fine and noble
things. It makes us feel good about ourselves. Like recycling, it
enforces virtuous behaviour (or so we’d like to think). It is the modern
equivalent of declaring ourselves a nuclear-free zone, only better,
because it requires deeds as well as declarations. Also, it sets a good
example for the less enlightened members of society, who don’t always
understand what’s best for them or for the planet."
