Paradigm shift?

A strange thing happened in my head today. I was reading a great book about sharks, who reached evolutionary perfection 200million years ago and have pretty much dominated their environment ever since. Then humans came along and started messing things up and now they are having to change their behaviour and adapt and they can't keep up and they're under threat. Now I normally hate stories of man's effects on the planet and wildlife. Normally upon reading this article I would be depressed and want to go outside and apologise to nature on behalf of the human race. But today - especially after reading that we wipe out almost 100miliion sharks a year for such reasons as soup and stupid Chinese medicine - I didn't think 'Oh, God, no.' I thought 'F**K YEAH!!! GO US!! WE RULE!!!' This is unusual for me, and I'm not sure where it'll lead. Am I now proud of humanity's destructive ways? Am I to revel in our imminent rendering of the planet as inhospitable to everything except cockroaches and Sharon Osbourne? (who's had so much plastic surgery she couldn't be wiped out by an H-bomb)
Maybe my subconscious has just realised that I can't handle the guilt brought on by the behaviour of 6 billion other people, and that I should just join 'em rather than try and beat 'em. Why should I care and bother and try to change things when all other humans now and in the past have gone the other way?
I'm off outside to stomp on a butterfly....
