We have been exploiting coal, petroleum for our needs by digging and mining the earth for decades.
Most of the extraction of petroleum is done in the name of storage for future needs.
In future, if technology reverts to hydrogen fuels this petroleum stored might go waste.
Also instead of natural methods, we use coal for power generation.
This coal once dug leaves huge cavities in the earth's surface.
These cavities can be troublesome in times of floods and can also be the cause of earthquakes.
Also, we have been wasting many resources including soils and water.
