There are a couple of things we would say.
One is, yes, if appropriate, but you need to take an evidence-based approach to that. Banning one thing doesn't mean the problem goes away; you could be replacing it with something else. We have seen authorities such as the Quebec government, the Danish Environmental Protection Agency and others say that, on a life-cycle basis, a plastic bag is better than some of the alternatives. We would encourage you to take, as in any decision a government would make, an evidence-based approach.
Second, we think there are cautions when you make choices on behalf of consumers and citizens. You're suggesting that they don't have the ability to do that. Certainly our industry strongly supports education and the right to a straw if you have a reason. Keep it behind the counter. Allow people to ask for it. Refusing them the opportunity, if that's the product they need.... Where does that stop? At what point of commerce do you make those decisions? We don't ban people from smoking today.
I think there are a couple of pieces there that we would encourage governments to think about when they make decisions: evidence-based decisions and the role of consumers in making their own informed decision on any aspect of the economy.
