Harmonic Biodiversity is Crucial to Survival

Biodiversity, as defined by E.O. Wilson, “is meant to be all
inclusive- it’s the genetic based variation of living organisms at all
levels, from the variety of genes in populations of single species, through
species, on up to the array of natural ecosystems.” This includes plants,
animals, insects, fungi, bacteria, and all microorganisms. All of these
things create what is known as a web. These things interact with each
other in some way there for they depend on one another throughout
their lifetime. There are many separate ways in which we can study
biodiversity. These ways include, genetic, species, community, ecosystem,
and taxonomic diversity. Biodiversity can be best number of species in a
given area, or scientifically, “species richness.”
Today, there is a biodiversity crisis facing us. This is
caused mainly by the destruction of habitats. This dramatically increases
the rate at which species decrease in number and become extinct. It is
appalling to know that we are the main cause of this. Over fishing,
pollution, over cutting, and an increase in population contribute to this
problem. Contamination of the environment of, for example, fish can in turn
harm humans who eat those fish.

Biodiversity promotes a healthy environment. Environments
rich in biodiversity are stronger and can with stand things such as
drought, disease, and other stresses that environments that lack it cannot.

In the video, during the drought, the side of the field with a more
diverse environment held stern as the other wilted away.Areas that are very
diverse are very important to humans as well. They provide a wide range of
pharmaceuticals such as aspirin and penicillin. Some 40 percent of U.S.

prescriptions are for pharmaceuticals derived from wild plants, animals and
microorganisms.

Old growth forests play a detrimental role in biodiversity
preservation. It’s most important feature is biodiversity. Old growth
forests provide us with many of the things
that we as humans take for granted, for example, breathable air pure water,
and pest control through birds, bats, and insects. In the Eastern U.S.,
most of the old growth occurs in small isolated areas. Scientists have come
to the conclusion that even if these matured areas cover a substantial
portion of landscape, it will not provide long term diversity for many
species that live in such a community.

Many environmentalists are increasingly concerned with this
biodiversity crisis. As humans we need to do our part to end this. Most
people don’t realize the overall and astounding effect of environment in
our lives. This is the world’s most important resource and every effort
should be made to protect the biodiversity of the Earth. Our very existence
hinges on such a thing.
