Billions Of Bacteria
We think humans are in charge of the world. But if you take it down to a microscopic level, there’s no way we rule the world. Neil deGrasse Tyson puts it into perspective and says, “Within one linear centimeter of your lower colon there lives and works more bacteria (about 100 billion) than all humans who have ever been born. Yet many people continue to assert that it is we who are in charge of the world.” How can we be in charge of the world, when there are billions of bacteria living in our colon, let alone the trillions that live everywhere else? This puts our existence into perspective (Your Dictionary).
