To Pee in the Sea or...

You know you've wondered this at least once: When you're out enjoying a lovely day at the beach and you 'gotta go', is it better (ecologically speaking) to urinate in the ocean or discreetly in the dunes?

Well, this and other kind of gross but equally important green bathroom questions were recently addressed by Ask Umbra on Grist. (see 10 gross green bathroom questions you never knew you had)

We suspect you knew perfectly well you had all these questions, and you were maybe just too embarrassed to ask. But it's okay. Really. Inquiring minds want to know.

The short answer to this one is pee in the sea, but the reasoning is surprisingly complex - which proves it's an EXCELLENT! question. Read the full rationale here > Umbra on peeing at the beach.
