Let me be quite blunt here – not all the data is in, but it doesn’t
appear too promising. It is now the
twenty-first century. The world is
crowded with humans with apparently no letup in sight; this trend does not take
into account the possibility of a massive and precipitous decrease in the size
of the human population due in part or entirely to the inevitable environmental
impact of human activity – not that unlikely a scenario.
However, let us say for argument sake that the human population continues
to expand without any genuine regard for accepting the natural consequences for
human activity. Honestly, living in the
present in ways that will help ensure a viable existence for future generations
does not seem to reside in the purview of modern human behavior.
Given the ravenous appetites of humans and the seemingly inexhaustible
collective need for material acquisitions, what kind of human world will the
future entail? What will the climate
look like? What will be the state of the
natural resources upon which human life depends? What will be the living conditions and the
general quality of life for the vast majority of the members of this remarkable
species? What will be the prospects for
establishing a human environment where peace would thrive?
In regards to the climate, this question is not difficult to
answer. With the ever-escalating rise in
the levels of greenhouse gases in the environment despite all the science that
has established a clear and unambiguous relationship between this increase and
the deleterious impact on the environment, we can expect:
·
Increasing
average ambient temperature worldwide leading to increased desertification, that
will lead to population shifts on a massive scale – some areas will be become
virtually uninhabitable for human populations.
·
Extreme
droughts in certain parts of the world and extreme weather conditions in others
with more violent storms, tornadoes, hurricanes, etc.
·
Increased
releases of dangerous and toxic methane gas, also a greenhouse gas, as a result
of the melting of permafrost in the northern climes as the temperature
increases. This effect produces a
so-called “feedback loop” as the increased emission of methane raises surface
temperature causing a further release of methane and on and on.
·
Accelerated
melting of land-based ice leading to an inexorable rise in sea level that over
time will have a devastating impact upon those populations living on the
world’s coastal areas. As land ice
melts, it reduces the reflective properties of snow and ice (referred to as
albedo) thereby increasing warming and further accelerating the melting
process. This is yet another example of
a feedback mechanism. Such dramatic
changes will necessarily lead to displacement of large numbers of people that
will inevitably lead to social unrest and war on a massive scale.
A thorough scientific analysis of the full impact of increasing
concentrations of greenhouse gases in the atmosphere on global weather
conditions requires complex algorithms to account for all the variables involved
and supercomputers to run the data.
Although this remains a work in progress, the results of this approach
have already shown itself to be a good predictive tool.
The examples cited above merely touch upon some of the most important aspects
of the impact of climate change on human populations. This is by no means an exaggerated
accounting. In spite of the massive
amounts of climate data that have confirmed these trends, governments
throughout the world – all too ready to accommodate corporate interests – are either
proposing tepid measures to corral and decrease the release of greenhouse gases
from the burning of fossil fuels or are doing absolutely nothing to avoid
future disaster. If left unchecked, the
atmosphere will become so overburdened with greenhouse gases that no solution
will be possible no matter how much effort and resources are thrown at the
problem.
Regarding the access of humans to the resources that are necessary to
sustain human life such as adequate food, safe drinking water, appropriate
housing, affordable health care, meaningful employment and a good education,
there is reason to believe that on account of the extreme and ever-increasing
inequity in regards to income and wealth, more and more individuals will slip
into an economic strata typified by poverty, desperation and hopelessness. Furthermore, as the human population on
planet earth continues to grow this will necessarily place a greater burden on
finite and shrinking resources.
The economic model that much of the world has come to regard as the
bedrock of human advancement, presupposes that progress is equated to and
dependent upon the relentless production, expansion and market share of
products. The manufacture of these
products depends upon finite resources, some of which are rapidly becoming
exhausted.
This wholly commercial outlook of life has led to its inevitable
conclusion – everything is for sale.
Consequently, large numbers of people throughout the world are unnecessarily
dying of starvation, have no access to safe drinking water, health care and are
made homeless because they lack the economic resources to afford these
“commodities.” The net impact of this
fundamental aspect of contemporary economic life is the unmistakable reality
that longevity is directly related to wealth – that the very small percentage
of the world population that have accumulated abundant wealth are outliving
everyone else. The level of individual
consumption that is required to maintain the desired quality of existence in
modern terms is essentially unsustainable in the long term. For these reasons, it is a model that is
bound to fail and ultimately fail catastrophically.
Furthermore, the ever- increasing population pressure upon the planet’s
finite resources is placing a significant strain upon the availability of the
necessary requirements for living. Not
only are greenhouse gases being introduced to the earth’s atmosphere at
alarming levels as discussed earlier, but a host of other poisons are entering
the air and water supply. These poisons
are by-products of commercial production and their ultimate impact upon the
biosphere is impossible to measure.
These issues are not being adequately addressed on account of the fact
that corporate interests are thoroughly enmeshed within the political systems
of most world governments. Although the
current economic infrastructure that predominates the vast majority of national
economies is being questioned from many different sectors it is not being
effectively challenged. For these
reasons, real change is highly unlikely.
Extrapolating the current economic trends into the near future and
examining the projections being made by climatologists from around the world in
regard to the climatic conditions, the picture that is forming is not a
pleasant one.
Given the growing inequality of wealth between the few that seem to possess
a staggeringly large portion of the economic pie and the paucity of wealth
possessed by the vast majority of the world’s population, it is patently
obvious that societies around the globe will be comprised of two tiers in which
the wealthy few will live abundant and lavish lifestyles within fortified and
gated communities with everyone else struggling with and competing for
shrinking resources – these conditions already exist in many parts of the world
and the situation will grow increasingly bleak and more hopelessly out of
balance.
Couple these conditions with the accelerated global impact of climate
change, as discussed earlier and you have a world in which the human species is
relentlessly besieged by forces that will rent and tear at human communities
everywhere. A number of somber scenarios
come to mind in this regard –
·
As the
sea levels rise due to the accelerated melting of land-based ice, human
communities living by the sea at what was once sea-level will be forced to move
inland on a massive scale. This kind of
chaotic and forced migration will bring with it opposition by those who already
live safely inland and would suddenly find themselves at risk – this kind of
opposition is so bound up with survival that wars of aggression would
necessarily follow.
·
The sea
will grow more and more acidic as the overburden of greenhouse gases in the
atmosphere increases the concentration of dissolved carbon dioxide. This already is having a deleterious impact
on coral populations and the health of marine phytoplankton – small plants that
are an essential ingredient in the food chain.
The increasing acidity of world’s oceans together with overfishing that
is a direct consequence of human population pressure, will inexorably lead to
the rapid diminishment of life in the sea; this process has been referred to as
devolution. The implications of this eventuality
on the human species - especially in regards to the supply of protein in the
diet - lies beyond comprehension; for, it entails starvation at unprecedented
levels.
·
Yet
another impact on the oceans as a result of the increased temperature of the
oceans is the possible disruption of the deep water thermohaline circulation
(THC) that is responsible for the transfer of enormous amounts of heat
throughout the planet. Such a disruption
would have major consequences for the global climate.
·
Havoc caused
by the unprecedented and wholly unpredictable onslaught of severe and prolonged
extreme storms and weather conditions will place a heavy and relentless burden
on human populations and the economic infrastructure of human communities
everywhere.
·
Members
of the affluent class would remain insulated from these dramatic and disruptive
changes for a time; however, as national economies and ultimately the global
economy begin to feel the full impact of the environment devastation, no one
would remain immune to the deleterious consequences of unsustainable human
activity.
·
Ultimately,
the intricate and interdependent systems that are required to maintain the
highly technical and mechanized social order of modern life would collapse
under the sheer weight of the global crisis and human societies would
necessarily need to adjust to a far more primitive existence. As a consequence, human populations would
shrink over time as the human world is overwhelmed by war, wide-scale famine,
severe deprivation and disease.
Finally, the cumulative psychological damage of these catastrophic
events would necessarily have a negative impact on individual and group
behavior adding to the increasingly chaotic nature of existence.
This is not a terribly sanguine look at the future. It does in my judgment, however, represent a
reasonable projection of the consequences of current human activity on planet
earth if nothing is done to significantly address the underlying issues that
demand our full and unmitigated attention.
In answer to the question, “Is the Species Smart Enough?” in regards to
insuring a viable future for the human kind, it seems that my answer is leaning
towards the negative with the open possibility that this analysis can be readily
updated to a more positive conclusion provided that meaningful reform in human
behavior becomes evident.
