It’s overpopulation. Too many people putting pressure on the surface of the earth. Causing the molten lava to squeeze out. And islands to flip over with too many people standing on one side.
Or........it’s the windmills; they create ever more resistance to the winds, slowing down the earth’s spin causing the surface tempature to rise because it’s exposed longer to the sun. i explained this to Siemans before they started building all the damned windmills, but no one believed me. Hah, now there’s proof I was correct!
