I am somewhat torn on this. The animation, sound design, and dialogue are all pretty good. You are also well researched and I appreciate you listing your sources.
It does however seem pessimistic and unproductive to say we should move to another planet but I know most of that was for the sake of comedy. I like that you're spreading a message but I think I would try and make the main ideas and comedy a little more separated because it sometimes feels hard to understand what you want from the viewer.
Other than that, great job!
