Nowadays, the
extinction
of various types of rare
species
of
animals
is imminent. Some people think that spending money on the preservation of them is a squandering of the budget. Others argue that the preservation of
animals
is a compulsory effort. I agree with the latter above-mentioned statement because they have the right of continuing their existence and are an integral part of the
ecosystem
.
Every living creature on the earth has the right of continuing their generations. Animal kingdoms have been living for millions of years all over the world even before human beings. They
also
contribute to the development of humans .
for example
,
according to
Darwin's theory of development, monkeys were the ancestors of humans.
Therefore
, human evolution in the future is dependent on the existence of other
species
.
in addition
,
ecosystem
stability is a
result
of interaction between a significant number of
animals
. Each
species
of animal play an important role in the
food
chain.
Subsequently
,
extinction
of them may have tremendous outcomes for other
animals
.
For instance
, in equator rainy forests, the
extinction
of a wolf
species
causes an increasing number of rabbits which destroyed a significant part of agricultural crops and the main
result
was a severe shortage of
food
in many villages.
As a
result
, the vanishing of some
animals
may have severe nutritional effects in some communities.
On the other hand
, it is a natural way in the
ecosystem
for
animals
to
extinction
on earth. The environment of the globe is changing and global temperatures are rising which is not a suitable condition for many
species
. As a clear example, millions of North Pole bears have died in recent years
due to
the melting of glaciers at the North Pole and the incident of temperature,
as a
result
, spending money to increase the survival of those is wasting because they will extinct regularly.
Moreover
, these
animals
need shelter and large amounts of
food
and potable water which can decrease the Human Resources of needy supplies.
For example
, a horde of elephants needs approximately 100000 million litres of water per year which can be a good reservoir of water supply for more than 1 million people.
Therefore
, human beings can save their supplements when these
species
did not exist.
In conclusion, I completely agree with laying out money on the preservation of dying-out
species
. They not only have the right to exist in the world but
also
can have a substantial role in the
ecosystem
and
food
chain.
