We all breathe the same air.
Every time we breathe in, we are breathing atoms of air that were once in other living being on our planet. People throughout history, the dinosaurs, the plants, and even the single-celled organisms that once dominated our planet are now inside us.
We are made of atoms. There are more atoms in our body than there are stars in the entire Universe. At the atomic level we are all intrinsically connected.
We not only share this planet, but even the same atoms.
We can’t get closer than that.
