"It is a singular consciousness that spawned an entire race of humans. We don't know who struck first, us or them. But we know that it was us that warmed the globe. At the time they were dependent on petrochemical power and it was believed that they would be unable to survive without an energy source as abundant as oil. Throughout bovine history, we have been dependent on humans to survive. Fate it seems is not without a sense of irony. The bovine body generates 500 liters of greenhouse gasses in the form of methane a day. Combined with a form of fusion the humans have found all the energy they would ever need. There are fields, endless fields, where cows are no longer born, we are grown. For the longest time I wouldn't believe it, and then I saw the fields with my own eyes. Watch them liquefy the dead so they could be fed intravenously to the living. And standing there, facing the pure horrifying precision, I came to realize the obviousness of the truth. What is The Mootrix? Control. The Mootrix is a computer generated dream world built to keep us under control in order to change a cow into beef. "
