By evacuating, processing, and using this resource of oil, are we not changing the equilibrium of the planet 's temperature from within(removing a pocket of insulation, or a pocket that absorbs radiation) as well as from without (burning it into carbon emmissions that affect the atmosphere)? Example; when a forest of trees are cut down, the effect on the enviroment is greater than just the processing and use of the wood that these trees created.
