I was also in that thread at the time.
I assumed you were claiming I said these things, as I'd already once asked how you thought it was an American thing, and since you were using "you" phrases. I guess that's the problem with English where the plural and the personal is the same.

It was at no point an american thing specifically, so I still don't get how you think it is americacentric. The fact that you haven't heard of it outside such a context doesn't mean it is, certainly not when you've been informed that it was relevant outside such a context. Taking care of nature is relevant across borders.
As I've already said, I'm not american, but it was relevant to me.
