I agree that it's a very hard problem and the change of the whole industry is required to fix it. But I believe, with enough resources and will it would be possible. The problem is, that nobody actually cares -- it's all about PR now only. For example, let's take food industry where regulations are enforced on all levels and restaurant, after poisoning their clients, can't simply say: "Sorry, we didn't mean that, we had no idea these mushrooms came from Chernobyl, but rest assured we won't deal with this supplier again".
