Endangered species


									A population of organisms which is in danger of becoming extinct because there are
only a few left, or because they are jeopardized by the changing environmental
conditions or predation parameters. Of course this animal are also threatened by
human activities, like deforestation, which decreases the amount of food, water or
living space. The International Union for Conservation of Nature (IUCN) has
calculated that 40 percent of all organisms are endangered, an evaluation helped with
the list of species from 2006. That is why many nations have laws for protecting and
conserving endangered species such as prohibition of hunting, creating preservations
where the animals and plants can thrive, or the restriction of land development so that
it cannot be affected by any human activity. But still, the problem remains because
many of the species threatened of extinction are not included into those laws. The
criteria for putting these species under protection and placing them on the list of
endangered, or removing them from that list, are not the same everywhere and that is
where the problems can begin. People decide which of them are worth saving and
which are undesired or unimportant. Although they are only a few of some species left,
no one takes any notice or responsibility and many of them vanish without the people
even noticing or knowing. Each of these endangered species are given a conservation
status, an indicator that tells us the probability that species has of extinction. Also,
there are different categories for threatened species, a general term used by IUCN.
They are: extinct(there are no more remaining species), extinct in the wild
(individuals only survive in captivity), critically endangered (extremely high risk of
becoming extinct), endangered, vulnerable, conservation dependent (these species are
not severely threatened, but they rely on conservation programs to survive), near
threatened (not threatened at the moment, but may be considered in the future) and
least concern (no immediate threat to the survival of these species). Ecologist can also
have a negative impact on the environment and its inhabitants, during their search to
find more about these threatened species. They have a tendency to look at the whole
ecological sphere, which decreases the value of individual creatures that are
overlooked this way. They do this mostly because there is a small percentage of areas
that are protected, and they have to be used into consideration when planning the
preservation of some species. These actions often raise serious ethical questions. The
main question here is, of course, why so many species are becoming endangered, or
worst, extinct. The most widespread cause it loss of habitat, mostly because of human
activity, but this also includes natural disasters. These species must then adapt to a
new environment, which is never easy, or they will die. Other causes include pollution,
too much exploitation, disease and climate change. Once again we can see here that
humans are most responsible for the disappearance of many animals and plants. By
using resources, energy and space, people make a huge influence on the wild life.
There is a very logical, but disturbing statement about this: as human impact on the
environment increases, the diversity of life decreases. Because it is so time consuming
and costly, many people don’t bother with preservation of different animals and plants,
and even question every person that does. But the fact stays, the salvation of these
species is necessary for humans because they provide many good things to us, such as
a source for products for human welfare, entertainment and arts, they are a sign of the
health of the environment etc.
