Beale: We've discovered million-strong dead masses out there. Our modeling shows that non-necrotic human life people... now have 14 or so years left on this planet. Could be quicker. And it isn't just the delts. It's starvation... the tenuous balance between population and yield. Disease, with a billion petri dishes out there stumbling and cooking in the sun, waiting to transmit God knows what to us while it transforms into God knows what. And in the end, the most likely outcome is that this rock will be cluttered with corpses to eventually rot into food for the trees. And it all becomes a strange temporary museum to an even stranger species that conquered it and marked it for a blink of its existence. This is why we do what we do.

Rick Grimes: What do you do, sir?

Beale: We're trying to beat the odds, Grimes.
