Diversity is life, uniformity is death
Danilo Anton
Widespread
processes of environmental degradation are taking place throughout
the world. The effects of human action have been profound and
cumulative. Earth’s atmosphere is being modified, introducing
uncertainties about potential consequences, which could be life
threatening. Water is being contaminated on every continent, in
coastal areas, and even in the open ocean. Simultaneously, the
principal fish species are being exploited far beyond replacement
levels, introducing profound disturbances in the main aquatic
ecosystems. Elimination of vegetation is promoting widespread
erosion, changes in hydrological regimes, and, frequently, floods and
droughts in areas in which they were previously unknown. “Scars”
that are often irreversible are being produced by mining operations,
as well as by quarrying for building construction or engineering
works such as highways or dams.
The combined
effects of these processes are affecting many species of plants and
animals, which are finding it increasingly difficult to survive in a
changing environment to which they have not had time to adapt. As a
result of human activity, the equilibrium of ecosystems is
being altered
and widespread modifications of their species compositions and
interspecific relations are taking place. A main consequence of the
deterioration of the physical and biological support of ecosystems is
the general loss of biodiversity — both number of species and
varieties.
Along with this
biological impoverishment, social and economic standardization are
rapidly reducing the richness of the world’s hundreds of cultures
and resulting in the loss of a huge volume of knowledge about nature
that has been accumulated over many generations. Macroeconomic trends
are forcing local communities into high-productivity, monospecific
agriculture or raising animals for commercial purposes, replacing the
enormous range of traditional crop and animal varieties by a few that
meet the conditions for short-term competitiveness imposed by
globalized international markets.
In much the
same way in which species and varieties are becoming extinct,
languages, beliefs, traditions, empirical knowledge, and whole
environmental-management systems are being wiped from the face of the
Earth by a shortsighted, mainstream culture that does not offer
appropriate substitutes for the sustainable long-term strategies that
are often part of the older and more experienced cultures.
The human and
biological diversity that is under attack represents the bulk of the
planet’s natural and human resource base; reducing diversity will
result in a gradual loss of options for the future, not only for the
current generations, but also for the many to come.
Resources
for the future
Although we
have only incomplete knowledge about current diversities, both
biological and cultural, we do know that some will become resources
in the future. Perhaps the flower of a certain plant contains a
substance that
can be used to produce a drug to treat a serious disease that does
not even exist yet. Maybe the shamans of a micronation in the Amazon
know about a plant that produces a glue that is 100 times stronger
than anything now known. Maybe this traditional group has a logical
approach to environmental management of its particular ecosystem that
can be applied elsewhere. The possibilities are infinite.
All species
have the potential to become resources; all present resources were
part of diverse assortments in the past. We cannot know which
elements are going to become resources. Societies possess a range of
potential resources today, but are experiencing a number of pressures
— some of them of a productive nature — that are having the
effect of destroying these resources.
How can we
protect our future resources? There is only one way: by protecting
today’s diversities. Highly diverse environments are full of
potential resources that must be protected. Although low-diversity
environments probably have fewer potential resources, they must also
be protected because we do not know their nature and potential. In
other words, all diversities must be protected. The overriding aim
should be to ensure not only the well-being of today’s societies,
but also that the wealth of the future is not depleted.
Diverstity of living systems
Diversity is the main resource of life. The future of living systems is a result of multiple current options. Diversity provides flexibility. It ensures that, even if some roads are blocked here and there, there will be alternative ways for life to continue. Uniformity is anti-life. Uniformity imparts vulnerability by not allowing other options. It can only be sustained with great investment and effort and, in the end, leads to extinction. Diversity is life; uniformity is death.
Living systems
base their survival on continuous, selective adjustments resulting
from small biological variations, genetic mutation, changes in
relations in their ecosystems, and the behaviour of species,
societies, and individuals. Living systems evolve in a subtly
coordinated, dynamic equilibrium among thousands of diverse organisms
with diverse functions that ensure the sustainability of the systems.
The elimination
or modification of any component of a living system, inorganic or
organic, produces changes that require a general readjustment of the
system. In practice, it is difficult to know what changes will take
place when one species disappears or a physical component varies;
however, we do know for certain that changes will occur. Change is
intrinsic to all processes and systems.
Because of the
complexity of natural ecosystems, it is practically impossible to
inventory all their components and still more difficult to define
precisely their relations. However, although we do not know exactly
how any system works, we can safely state that the strength and
stability of any living system depends on the depth of its
diversities and on its degree of diversity. Depth of diversity is the
history that generated and allowed the development of the system’s
diversities, and degree of diversity is the level of differentiation
or dissimilarity developed by a given system compared with others,
both locally and globally. The natural tendency of local systems is
to maintain their degree of diversity and to increase their depth or
historical richness. Humans may obstruct these processes. For our
own future we should preserve and even estimulate the healthy growth
of global and local diversities.
