The Pixar Theory

Up

It's possible that Charles Muntz, the antagonist of Up, learned of this startling rumor, giving him the idea to begin inventing devices that would harness the thoughts of animals, namely his dogs, through translator collars. Those collars indicated to Muntz that animals are smarter and more like humans than we think. He needed this technology to find the exotic bird he's obsessed over, and he even comments on how many dogs he's lost since he arrived in South America.

But then Dug and the rest of his experiments are set free after Muntz's demise, and we don't know the full implications of that, but what we do know is that animosity between the animals and humans is growing steadily. Now that humans have discovered the potential of animals, they are beginning to cross the line. To develop this new technology, the humans begin an industrial revolution hinted at in Up.

[Some have pointed out that Muntz was working in South America before the events of Ratatouille. This is true, but it is not explicitly stated how and when he developed the collars. Also, we know Ratatouille takes place before Up for several reasons. In Toy Story 3, a postcard on Andy's wall has Carl and Ellie's name and address on it (including their last names to confirm). This confirms that in 2010, the time of Toy Story 3, Ellie is still alive or hasn't been dead long. This supports the idea that Up takes place years later.]

In the beginning of Up, Carl is forced to give up his house to a corporation because they are expanding the city. Think on that. What corporation is guilty for polluting the earth and wiping out life in the distant future because of technology overreach?

Buy-n-Large (BNL), a corporation that runs just about everything by the time we get to Wall-E. In the commercial from the movie, we're told that BNL has even taken over the world governments. Did you catch that this one corporation achieved global dominance?
