As A.I. takes over our world, many are concerned about the potential carbon emissions and water usage. Not concerned enough to stop generating images of Super Mario if he was fat and in World War II — but, you know, concerned.

Slowly but surely, companies are responding to these concerns. Microsoft, for example, recently announced that it would be buying potentially billions of dollars worth of human poop and other excrement.

What does this do, you ask?

It mainly gets people to stop asking Microsoft how they’re going to prevent themselves from totally burning down the planet. But it also (allegedly) stops things like manure, human waste and agricultural runoff by, well, kinda just burying it really deep underground.

Does that work? They say it does, and why wouldn’t we trust them?
