Finding Resources 3052
There has been a paradigm of prospecting for minerals and
fuels and devising methods of extracting what has been found buried under
sometimes miles of rock strata. During each year that passes the easier
deposits are found and mined leaving the deeper more expensive deposits in
place. With each passing year, Engineers devise ever more elaborate and
intensive means of getting to the resources and bringing them to market. Where
once a tunnel was dug into a coal seam and the coal scraped out and rolled on
rails to the tipple, now the practice of removing entire mountain tops to
reveal the coal has been made feasible due to the relative costs of the other
methods and the other sources of energy.
Even though there may be a century or two of coal still
available for the finding and taking, there remains two variables in the
formula that cannot be ignored. Coal is primarily Carbon compounds and Ash
bound up in a clump that we burn. While we obtain the heat from the chemical
reaction of the Carbon and Oxygen of the Atmosphere, the waste products of that
reaction are CO2 and the Ash. That CO2 mixes in the upper atmosphere and hold
the sun's heat there for increasingly longer times. The Ash contains all the
other elements that do not burn in the furnaces. Some of those elements are
heavy metals that all are toxic to humans and other animal life. Lead, mercury,
arsenic, and radioactive elements like Uranium are all present in that Ash. We
must contain that Ash and keep it out of our water supplies so that we do not
poison ourselves.
Fortunately, geologists calculate that the feasible amount
of coal and oil that we can find will last only a couple of centuries. This
means that even if today we fail to curtail our burning of fossil fuels, there
will be about 800 years of recovery time to for us to design a world that is
compatible with the warmer climate, design methods of extracting the CO2 from
the atmosphere and replace our energy production with sources that do not
destroy our biosphere.
There is no reason to expect that the fossil fuel
corporations will ever voluntarily alter their modus operandi to do anything
differently until the supplies run out or become too expensive to extract and
distribute. Therefore, the world will be plagued with a period of degradation
before it reaches a place of sustainability. The energy providers will however
begin to dabble in the so called "alternative energy" methods in
order to be ready to switch over as the cost ratios change. Some of those ratio
factors will be the force of public opinion and how fast the environment
changes due in part to the impacts of their enterprise.
