I just posted something about the impact we humans are having on planet earth. It was a documentary I listened to on the BBC world service in the wee small hours 3 days ago during my customary insomnia and about which I've not been able to stop thinking. I'd love it to spark a discussion but it looks like it's dropping into oblivion

This is probably not the best way to try to hijack this thread. If it was interesting and/or warranted discussion I'm sure folks would have started discussing it.

I'll concede your first point but I don't think your second always holds true.
