The U.S. Geological Survey is right on track and should provide a wake-up call for all on Earth.
1. The Earth's crust has been estimated as about 50 miles thick.
2. The crust is made of blocks and slabs of rocky material lying irregularly in layered piles.
3. It is the wreckage of a more even surface of billions of years ago than what we live on today.
4. Shrinking and swelling in the interior of our Earth and in the Earth's crust caused an upheaval of change as huge layers of rock slid over each other and settled into position. However, areas of rock were off balance and ready to fall or crack, which could be caused by slips along old cracks (faults) or new faultings in the Earth's crust.
5. Oil has been serving planet Earth for millions of years in its underground purpose and mankind has been sucking it out of its hole daily in fewer than 200 years, adding to the demise of the Earth's crust.
The gaping holes caused by removed oil in the ground that far down is left to nature. Is this not a problem caused by human activity?
