...and possibly goodbye from them

Top story today is of the danger of species becoming extinct due to global warming. Am I alone in wondering just what it is we are getting our knickers in a twist about? After all, environmental factors have been killing off species throughout history - anybody seen a dinosaur lately? I see a certain similarity here with the arguments over fox-hunting. As far as I could see (and I am a townie who knows nothing of country life) it had little or nothing to do with foxes or dogs or one creature tearing another to pieces - after all, this is the natural order of things. No, what was at issue was human behaviour - it was OK for a pack of dogs to chase and kill a fox, but not OK for people to specifically organise such an event, and then to watch and get enjoyment from it. The same people who were so vociferously anti-fox-hunting would probably see nothing wrong in a TV program showing a lion hunting down and killing a gazelle. In the same way, the problem with the possible extinction of species due to global warming is not that this sort of thing doesn't happen naturally, and that these species may well become extinct in due course anyway, but that what is happening is the result of human behaviour. I'm not arguing for or against, but it seems to me that we should be clear in our minds about just what the argument is. There may be good reasons for trying to stem the tide of global warming, but I'm not sure that the possible extinction of species is one of them.
