The word biodiversity
is made of two words. Bio means life and diversity means variety. It was coined
as one word seeing the contraction of biological diversityon planet Earth. Since
then it is being defined differently by different schools of thoughts in
biology.
Biodiversity definition by scientists
Scientists
prefer using the broadest possible biodiversity definition.They don’t want to overlook
any aspect of what is in exceedingly complex subject. However, one of the
largest problems facing scientists, government agencies and environmental
groups is;
HOW EXACTLY TO DEFINE BIODIVERSITY?
Dictionaries’ version
Dictionaries
are generally silent on any kind of controversy. They define the most general
outlines of the subject. But most have some elements in common. Most take into
account that it must refer the
A glimpse of biodiversity |
number and variety of plants and animal species.
They also hint that these species occupy a particular geographic region.
A
few dictionaries include the concept of the variability of those plants and
species. One or two include the variability within and among ecosystems as well
as within and between living organisms.
Best definition of biodiversity
One
of the best biodiversity definitions we have found comes from The Center for
International Environmental Law.It says;
"biodiversity is the variability of all
living organisms including animal and plant species of the genes of all these
organisms and of the terrestrial, aquatic and marine ecosystems of which they
are part"
Let its scope define it
Developing
a biodiversity definition is problematic no matter who is doing it because
biodiversity is a very broad topic.
Also
it includes everything making it very hard to exclude anything. For example
while every biodiversity definition includes plants and animal life, not all
include the soil or water that sustains that life, although to be totally fair,
most do so.
What about Homo sapiens or human beings?
Also
not every biodiversity definition includes human beings. Complicating the
matter even more is the problem of whether a real comprehensive definition of biodiversity
should include only those species that humans find useful or all the given
plant and animal species of an area.
With
such differences, it is almost impossible to come to a conclusion about the
meaning of the term, let alone the scope of the topic.
No action because of no unified definition
It’s
quite confusing what biodiversity should cover and what should not. That is why
those who want to do something to defend it have no point to start. While those
who just want to be clear on its concept are still unable to do this.
Another
group is not much worried because it believe biodiversity and progress can
never coexist. Mostly progress is done everywhere at the cost of variability oflife.
To
be upfront if something cannot be defined easily and concisely how can the
issues presented by it be prioritized let alone having resources allocated to
resolve them.
In
view of no unified biological decision it is not important what should be the
best one but what we must do to never let it contract further.
