Equity. I just don't know how we'll ever achieve it. A common enemy of the human race, maybe? We've already perfected fighting each other. Maybe if a "physical something" were attacking us, that we could kill; we might find a little more "human camaraderie".

Put a scooby-doo-type mask on climate change, so we can have something physical to try and punch. But "Jinkies! It was something intangible this whole time!".
