Did you see the study on why the earth has shifted a few degrees on its axis due to ground water being withdrawn, and moved to other parts of the world. Gee I guess then that pulling an ocean of oil out of the ground had zero effect.
Our underground caves should be getting bigger. Soon earth will implode because it's hollow inside. :rofl:
I'm suprised no one has bored a hole to the core to harness the magma for energy! :lol:
