Modern-day Noahs
"Recently scientists have recognized that failure to stop the loss
of biodiversity risks the collapse of the web of life as we know
it. And if this calamity happens, scientists say the endangered
species will likely be us."
This concept
is at first difficult to grasp. Collapse of the web of life? But as unreal as
this may seem throughout
the world, scientists are documenting the decline and even outright
collapse of ecosystems. Here in British Columbia, the salmon fishery
is an example of just one of the ecosystems in trouble. Already, 142 runs of
salmon have gone extinct, while over 600 more are on the verge
of disappearing. A further 803 other species are classified as "at risk" by the BC
Ministry of Environment, partly because of an unprecedented rate of habitat destruction,
such as old growth forests.
BC seems not to have grasped the important fact that the health of its
economy is dependent on its ecosystems. For example, if the
BC fish stocks are in trouble, and salmon species are becoming extinct,
this has repercussions on the livelihoods of fishers and the coastal
communities that depend on this source of food and income. And since
salmon are a primary food for bears, a lack of salmon will lead to
starving bears, which leads to further ecosystem collapse.
When
one species declines it causes a ripple effect and other species that depended on the declining species
also suffer. We know so little about how ecosystems work and they
are declining so rapidly, that repairing them may be beyond our capability.
"Time, however, is growing short. Nature's machinery is being demolished
at an accelerating rate, before humanity has even determined exactly
how it works. Much of the damage is irreversible."
Paul Ehrlich, Ecologist
We have
allowed ourselves to get into this situation partly because we have
been operating in a bizarre world where the discussion of economics
takes place in a vacuum. Somehow we enter into discussions about
business and resource extraction without considering the damage to ecosystems and the loss of services they provide.
We talk about the number of jobs that cutting down a forest will
produce, without also discussing the losses this incurs: the loss
of clean air, clean water, habitat
for spawning salmon for fisheries, habitat for thousands of species,
recreational opportunities, and tourism opportunities.
"The environment makes up a huge, enormously complex living machine
that forms a thin dynamic layer on the earth's surface, and every
human activity depends on the integrity and the proper functioning
of this machine. Without the photosynthetic activity of green
plants, there would be no oxygen for our engines, smelters, and
furnaces, let alone support for human and animal life. Without
the action of the plants, animals, and microorganisms that live
in them, we could have no pure water in our lakes and rivers.
Without the biological processes that have gone on in the soil
for thousands of years, we could have neither food crops, oil,
nor coal. This machine is our biological capital, the basic apparatus
on which our total productivity depends. If we destroy it, our
most advanced technology will become useless and any economic
and political system that depends on it will founder. The environmental
crisis is a signal of this approaching catastrophe."
Barry Commoner, The
Closing Circle, 1971
Part
of the problem is that we have lost the understanding of the original
meaning of economics. The word "economy" comes from the Greek word
'oikos' (house), and 'nomos' (manage); so "economy"really means
managing the house, managing our home.
But we have been managing our affairs on earth very poorly. Instead
of saving the principle (the earth's resources and
all its species), and spending the interest (the extra wealth the earth
generates) we have been rapidly depleting the principle almost as
quickly as possible. Instead of practising a form of ecosystem-based
forestry for example, to ensure that there will be old growth forests
in perpetuity, we are simply liquidating these assets as fast as we
can.
"Liquidating old-growth forests is not forestry; it is simply spending
our inheritance."
Chris Maser,
Biologist and Sustainable Forestry Consultant
Perhaps a useful way of reminding ourselves of the connection between
economics and ecosystems, our life-support systems, would be to change
the emphasis in this important word to "Eco-nomics." This would help
us to start seeing the connections between our actions and our future,
that by disturbing the delicate web of relationships, we impact our economic or monetary wealth as well.
In recent years many new approaches to managing our resources have
developed. These approaches come from perspectives that say to manage
a resource well one must be able to withdraw its wealth without compromising
the diversity, stability and resilience of the ecosystem. Rather these
qualities must be is maintained in perpetuity. A new field of research
has developed, 'ecological economics', which seeks to right the
imbalance in our traditional economic thinking. Ecological economics
recognizes that economies are embedded in and dependent upon the earth.
With this new understanding the need to create parks becomes even
more important. As we rapidly destroy the ecosystems that generate
our wealth, that provide us with the basic services for our survival,
clean air and water, and food for example, it is imperative that we
conserve some remaining threads so that life as we knew it can go
on. We are really acting like modern-day Noahs collecting and protecting ecosystem
examples in parks.
For more information on how we can manage BC's resources in a way
that both protects nature and creates jobs see our Jobs & Environment
program.
