Bill Nye explains ‘we’re all one species’ in new TikTok science video

If anyone can give humans hope that we should start treating each other as equals regardless of our skin color, it’s Bill Nye the Science Guy.

“Our skin is where we make vitamin D; if you don’t get enough ultraviolet, then you don’t get enough vitamin D,” Nye continued. “But if you get too much ultraviolet, then you break down your folates. You have to have it in perfect balance. And because the ultraviolet varies, the color of our skin varies. That’s why we have different color skin.”

But this wasn’t just a simplified scientific explanation of why we all have different skin colors. Nye also wanted to drive home a bigger lesson. We are all the same underneath, and we need to treat each other equally, instead of by the color of our skin.
