Oh, and one thought I had recently, which could be from the "Institute for Plain Bonkerism":
Why would anybody be interested in turning this planet into a inhabitable desert? Some people fancy the thought of terraforming other planets like mars, to make it a place where humans could live. What if somebody already lives on that planet? Asking them to help change their climate would be out of the question, but turning them into money obeying slaves, you can bring them to do anything. Mankind controlled by extraterrestrial lizards would fit nicely into this model (if you could call that bonkerish thought a model).
