If you could teach everyone in the world one thing, what concept would have the biggest positive impact on humanity?
That there is only one race, and it inhabits the entire planet.
Instead of race, I would use humanity. There is only one humanity.
That's okay.... I pass. I am not even trying. Raised without god, haven't try to kill myself or kill somebody else. I am not preaching anything, I am braging and stop following me. I am a godless, selfish none vagina.
I'd teach them the Peter Principle where everyone rises to the level of their own incompetence.
Leave things alone
@Matias mostly plants, animals, rocks, hills, mountains, water. We mess everything up. We should stop and leave things be. We have enough.
