Life at the Planetary Scale

“The face of the Earth viewed from celestial space presents a unique appearance, different from all other heavenly bodies,” observed the Soviet scientist Vladimir I. Vernadsky, in 1926. Decades before spacecraft visually confirmed the striking beauty of Earth’s blues and greens set against the black of space, Verndasky identified—correctly—that the planet was indelibly changed by the “living film” that covered it. Earth created life, and then life shaped the Earth.

The biosphere has made and remade the planet’s atmosphere, chemistry, climate, energy balance, landscapes, and more. Earth is only the way that it is because of the effects of life. Life, then, is not only interconnected to life, but it is also entangled with the rock, water, and air of the planet itself.

Find a quiet place to sit. Breathe in. Consider the origin of the air you just inhaled. Where has it been? Who has it passed through? Hold the breath. Consider philosopher Achille Mbembe’s idea that breathing is not an individual act, we “share the vital breath.” Breathe out. Consider Vernadsky’s claim that “no living organism exists on earth in a state of freedom” because all organisms on Earth are connected through respiration. Repeat, seeking an answer to the question: With whom are you connected through breath?
