It is no secret that our world is
changing rapidly. Faster than most of its denizens and biological processes can
compensate for, and in fact far faster than most of us realize. Modern humans
have only existed for a couple hundred thousand years, a fraction of an
eye-blink in the 4.5 billion year geologic timescale, but in just the last century or so our activities have
facilitated global changes at an unprecedented rate. Stephen Hawking,
world renowned physicist and science advocate, has said that “The world has
changed far more in the past 100 years than in any other century in history.
The reason is not political or economic but technological — technologies that
flowed directly from advances in basic science.” Technological
innovations have greatly helped us to thrive and spread by exponentially
increasing the speed by which we obtain and consume natural resources. Now as
the human population steadily
cruises past 7 billion, it is becoming ever more apparent that the
unbridled success of the human race has had an inverse correlation with the
collective health of the biosphere.
There is an ever growing mountain of
empirical evidence revealing and detailing relationships between various human
activities and their harmful effects on the natural world, and it is understood
better now than ever before that we are causing or contributing
to the rapid degredation of the entire global ecosystem.
It is well understood that to continue on in the way in which we have been going
is simply suicide
for our species. But what are we most concerned with in life? Pretty much
the same things we have always been concerned with; Ourselves, our friends and
family, our things, money. And what does the average person understand of the
natural world? Or how anthropogenic forces threaten it on a global scale, or
how their personal actions impact it? Not much. How can we be so far removed
from the rest of nature that news of its destruction causes little reaction?
The evidence is there. The scientific community exposes issues, makes
predictions, and proposes solutions, but public
and governmental reaction is minimal at best. When we
step back and observe the environment
and biodiversity slipping away, and contemplate the future that awaits us
if we refuse to change, why are we not astonished that we continue to happily
meander down this ruinous path? In his excellent 1999 article
in World Watch
Magazine, which I will explore here in this blog post, Ed Ayres thoughtfully investigates this urgent question.
Perhaps we have grown accustomed to environmental doom
and gloom forecasts to the point that it no longer fazes us. Global
environmental concerns are the subject of increasing scientific research and
discussion, but for the vast majority of people these issues continue to lie
just outside our range of personal concern. For years now scientists have
warned of ongoing “megaphenomena” which evidence suggests are greatly magnified
by human activity and gaining momentum, working in concert to threaten all life
as we know it.The four big ones according to Ayres are:
1. Rising CO2 Levels
Changes in observed atmospheric CO2. Black line is adjusted for seasonal changes and shows a
constant increase.
The increase of atmospheric carbon dioxide and the resulting effects have
been a hot topic for a while now, and like with most hot topics, there is
debate. However in this case much of the debate comes from those who are utterly misinformed. Many still believe that global climate change is not a man made
issue, but a perfectly normal natural cycle or even a myth. Popular
conservative radio show host Rush Limbaugh maintains
a stance that global warming is a hoax perpetrated
by the political left, and frequently brings it up on the air. Considering that
Limbaugh is one of the highest paid
people in broadcasting, it is frightening to think millions of people may actually believe him. The truth is the
scientific community is nearly unanimous in its stance that global climate change is man made and due largely to
CO2 output. However, the general public is not so united,
thanks in part to people like Limbaugh. In
addition to warming by greenhouse effects, rising atmospheric CO2 is leading to
the acidification of the ocean, which is bad news for any creature with a calcium carbonate shell or exoskeleton. Logan (2010) and many other studies predict that ocean acidification will negatively affect global food systems in a massive way.
2. Rising Extinction Rates
A third or more of amphibian species are currently threatened with extinction
The evidence is overwhelming. Habitat destruction,
overexploitation, pollution, climate change, and other manmade causes are
driving plant and animal species to extinction faster than it has ever occurred naturally. In their article, Wake & Vredenburg (2008) discuss the current peril of amphibians, a
class of animals in which a third or more of its species are threatened with
extinction. They support the common idea that the plight of the amphibians, who
are susceptible to slight environmental
changes, may be a sign that even greater biodiversity catastrophe is looming on
the horizon.
3. Rising Consumption of Resources
Changes in global resource use in the 20th century

Inhabitants of developed nations use up an incredible amount of natural resources, upwards of 40 tons per person per year in some
places. With world population growing, and more and more places adopting a more
“modern” lifestyle, global rates of resource consumption could potentially
triple to 140 billion tons annually by the year 2050 according to a U.N.
environmental panel. This rate is far beyond sustainable. U.N. representatives warn
that nations MUST decouple economic growth from resource consumption.
4. Rising Human Population
Trends in world population
Perhaps
the most controversial problem that we face as a species is that of overpopulation. With global
population predicted by many to surpass 9 billion by 2050, we are fanning the flames of the previously
discussed issues. More people means more resources and space required to
sustain the human population. Without a doubt we must wisely manage the
environment to account for human ambition, but more importantly manage the
human population (Luck, 2007).
So why is
there such little meaningful reaction to these issues?
Ayres cites many potential
causes. Among the most emphasized is over exposure to confusing
information. Much of the present day media is privatized, and so what reaches the eyes and
ears of the public is often skewed by political or economic agenda.
Folks like Rush Limbaugh spread nonsense that is readily heard and absorbed,
while real news is buried, unreported, or distorted. More than ever we tune in to biased corporate media
sources which are most interested in influencing how we spend our money, and
obtain less of what we know from people who actually care about us. We must be very selective of
where we obtain our information and always maintain skepticism. Children
are especially vulnerable to being manipulated through media and misinformation.
Through constant bombardment of information we can easily become emotionally distant
from world issues. Around the clock we hear about environmental problems and eventually begin to tune
them out, silencing them with music, movies, technological toys, and other
forms of entertainment or simply ignoring them. Education is another major factor. Why would we care about something we don't understand or even know about?
Much of the dislocation comes from
shortcomings in education, especially in early childhood when we are most
impressionable. The value of raising children with at least some
close contact with the natural world, the thing that allows us to live, cannot be understated. Digital
wilderness is no substitute for the real thing. With fewer and fewer children
growing up with any deep personal connection to nature, it is likely that fewer
children will grow up with any real understanding of nature, let alone a desire
to preserve it. Children must learn perspective, how we fit in the world in
relation to the rest of nature, and how the Earth reacts to our actions. Children should understand early on that we have
engineered serious problems for ourselves and the rest of biodiversity for
which we must rapidly make changes to amend. Perhaps most importantly, we need to look
not at technology as our savior, but at ourselves. We, as a species, must rise
up and act heroically by changing our behavior and educating the next generation
as well as ourselves on the ways which we depend on the world that we are quickly degrading.
