The more I get into evolution from a big picture, the more you realise that species have come and gone. Evolution has always been triggered by change in the environment, or rather, change in the environment has triggered evolution and change in diversity and species. The more I realise this, the less I seem to care about climate change. It's like "yeah, whatever, this has happened before. We'll just have to adapt and it depends on where the threshold is but we'll get to it eventually".
I'm not advocating exploitation of nature and think that it's ideally better to go back to a more primitive state of living in peace with nature if we can't figure this out.
What I'm trying to say is that in a way I'm not really scared of this climate change, on some level I find it rather exciting.
