How come Canada has snakes? "Reptiles need constant heating". Umm Canada gets pretty cold, it gets hot in the summer, but where did the snakes go when it snows?

Interesting, but reptilian mind control for desertification is far fetched.

Despite America being an Orc stronghold. Orcs need deserts. They're not happy unless you're building them a well in the desert. Not happy unless they're coming through the dark portal. There is obvious Orcish mind control today.
