Tomorrow's Quote Today

The first living cell came into being nearly 40 million centuries ago, and its direct descendants are in all of our bloodstreams… In each of you are one quadrillion cells, 90 percent of which are not human cells. Your body is a community, and without those other microorganisms you would perish in hours. Each human cell has 400 billion molecules conducting millions of processes between trillions of atoms. The total cellular activity in one human body is staggering: one septillion actions at any one moment, a one with twenty-four zeros after it. In a millisecond, our body has undergone ten times more processes than there are stars in the universe, which is exactly what Charles Darwin foretold when he said science would discover that each living creature was a ‘little universe, formed of a host of self-propagating organisms, inconceivably minute and as numerous as the stars of heaven.’
Paul Hawken, The Unforgettable Commencement Address 2009
