~nature or ~earth group?

I have a nice video about butterflies to post. It's not really ~enviro material because although there is a little bit of mention of climate crisis I want to post it mostly because "aren't butterflies awesome look at these awesome butterflies and how cool they are"

Sure it could go in ~misc but it seems odd there's a group for ~space and not one for down here on ~earth. I prefer ~earth to ~nature because I think there's human earth stuff which is cool too (I know, I know, humans are part of nature but you know what I mean). Also because it balances with ~space.

Anyway, was just a thought. Not going to lose sleep over it.

Additionally, in the sidebar, putting group descriptions in the title attribute might be useful - so I don't have to click into each group to see what it's criteria is when I'm trying to find where to post something non-obvious.
