Actions Speak Louder Than Words.
Local councils are considering banning the use of plastic bags in town centres - those in London are proposing a levy of 10p per bag similar to that which exists in Ireland. All very commendable but I wonder if the real problem is that to change people's behaviour, you have to make it easy for them. Otherwise they'll just grumble and take the hit. Things will improve but not as much as they might
I make the effort. I keep some reusable, supermarket-provided bags in my car so that I won't use plastic bags. Trouble is, I generally remember this fact when I'm waiting at the till!
Somebody needs to create a bag that collapses to such a small size that you can carry it in your pocket (or has the same effect) - then behaviours might radically change. Punishment no doubt works with some, so too does encouragement but facilitation is a much better marketing tactic.
