Clima! I also think strange things happen with the earth's subsoil. Of course, the inner core of the world is growing because humans have been taking Oil and Gas out of the earth since 1846, and therefore there is room for the inner core to grow, and therefore the heat of the earth is growing from within.
what gets into the ground when oil and gas are taken up? what material has the ability to stabilize the subsoil as good as oil and compressed gas nothing can replace Oil and Gas so subsoil worldwide is and will be unstable.
