Life clings to this blue planet like a miracle. It is amazing how effective living things are at garnering the energy of the sun and converting it into chemical energy.
The heart of this process is a reaction in which a photon provides the energy for a chemical reaction, combining carbon atoms into a sugar molecule.
It is wonderful how efficient that process is, and awesome to see the proliferation of diversity that has evolved from it.
Geologists tell us that atmospheric oxygen appeared when living cells unlocked it from earth's rocks. Before life there was hardly any oxygen in the air.
This simple reaction, capturing the waste product of nuclear fusion, has also fueled every idea that every human ever had.
The symphony of life is one of the great discoveries of our time.
