I’ve been browsing antique jewelry a lot lately and wonder about this. With jewelry specifically I think about hair, coral, pearls.

Then that extends out to animal skins, bones, human relics, etc.

What makes one thing gross but the other okay?

    Water is created and destroyed by nature, non-stop since forever.

    Photosynthesis:

    6CO2 + 6H2O + light energy → C6H12O6 + 6O2
