Idea for what I could base my moving image on?

So I was looking for things to do for my moving image, I had the idea of taking the experiment I did with stop motion and doing my walk to Uni in different styles of moving image, however i felt this might be a bit boring. I also had the idea of taking a famous scene from a movie or TV show and making an Anomatic animation with the audio, witch in a way sounded rather fun to me. At the time  I went though a post apocalypse obsession and whilst searching for images on google i came across this.

This gave me the idea of doing an animation based on the concept that the huge fast food restaurants would be the down fall of humanity and they would destroy the world. I found this concept rather amusing but at the same time the damage Mcdonalds has on the rain forests is huge all so they have more land for cattle that then get slaughtered to make burgers. Mcdonalds slaughters 67 thousand cows every day to make their burgers and they uses land from the rain forests to create cattle farms. Imagine if the demand for Mcdonalds continues to rise, the more burgers they bring out the more cows they kill, which means they need more cows, they need more land to house these cows, which means the rainforests get chopped down even more. Then add KFC and burger king to the mix and thats a lot of rain forests. 

Could one day this result in the end of the world as we know it? Could the oxygen run out because we cut down to many trees so they isn't enough oxygen being produced for us all? Or will the ecosystem just collapse? Ethier way I believe I could have some fun playing with these concepts.
