Tick tock! We are arguing the same stupid point that was settled years ago. While we discuss the finer points of who is right, the window to prevent serious, serious damage to our environment closes. OK, we KNOW that we are responsible for the mess. that point is sort of irrelevant because, despite an admission of guilt, no one seems to be in a rush to do something about it. And the longer we dither, the fewer the options and the less effective the solutions. It won’t be long before we simply have to try to protect against the worst of the harm that we have caused by endless discussion.
