We live in a world where we have to have a huge fight to persuade people to take some trivial action to reduce an immediate and very obvious risk to them and others, and even then a lot of them refuse to wear masks because, oh I don't know why because.
What's the chance that we're going to persuade people to take some fairly non-trivial action to reduce a risk which will kill mostly their children and grandchildren, about whom they only pretend to care. And the people it's killing now? Well they live far away, they're poor, and they have skins the wrong colour, don't they?
The chance is zero. Eventually it will rise above zero, but by that time it will be thirty years too late. It's already ten years too late.
