The reference to 'agenda 21' in my post was ment like a tongue in cheek 'wink wink, nudge nudge' thing.

Have not learned about it in primary school, but I know about it thanks to the internet. And know that there are different thoughts about it. It would be a bit of a sidestep for me right now to go into all of that.

Thank you for the links and summarizing the subject, it is an interesting subject in itself, probably worth a post or more. And it would result into quite a large comment section, I guess.
