Implicating nature → outside
Link to implication

Reason:

Since it's a tag for natural outdoors scenes, I can't think of any instances where outside wouldn't apply.

(And it looks like this is needed, since there's a lot of posts under nature -outside)

What about inside of a cave? I guess most people wouldn't tag that with nature though...

Well damn, that's true. Some underground or cave scenes might potentially be tagged as nature. It's not supposed to be tagged for barren scenes, but I'm thinking of something like moss-filled cave, etc.

I guess I'll just have to tag script those manually..

what about the scientific journal "Nature"

Not the best example in a pinch, but I was thinking more about pictures like this:

An extremely detailed post like this might end up with the tag as well.

Edit: Interestingly I ran just across this one my accident, which was tagged outside.

Denied for reasons mentioned (inside caves, has windows which feature prominently a scene from nature, etc). It almost would have worked and was an interesting idea though.
