From the Paper:

"Earth's atmosphere is not in a state of chemical equilibrium. It is full of gases that have an affinity for each other. Oxygen, nitrogen, and methane exist in sizable quantities, and left to their own devices, would quickly interact to form a new atmosphere of inert gases, very much like Mars' atmosphere (Margulis and Lovelock, p. 13(2)). So the persistent presence of uncombined methane, nitrogen, and oxygen in the atmosphere is strong evidence that something is replenishing these gases as fast as they naturally interact."
