Sitting on a rock in the middle of the forest at dusk, as a 21 year old scientist, I realized the oxygen in my lungs was from the trees around me, and my CO2 fed the trees that sheltered me. The elements in the rock I sat on were elements in my body. Everything is made of the same things, and to this day, that moment 45 years ago feels like yesterday. I have dedicated my life to all that don’t speak.
