nature,
the
environment
which
human
beings
live
by,
is
magnificent
and
unique.
there
si
only
one
earth
with
super
living
conditions
in
the
universe.
we
should
have
cherished
nature
and
preserved it.
conversely, however, we
have
been
continually
spoiling
it,
even
to
a
shocking
degree.
now
let's
see
what
we
have dong. thousands of trees have
been
cut
down
per
year,
which
has
caused
soil erosion. hundreds of thousands of
tons
of
cfcs
have
been
left
in
the
higher
sky in the last decade
which has led to
the
ozone
layer
leak
above
the
south
pole
that
covers
an
area
of
that
of
the
united
states.
million
tons
of
fuel
containing
nitrogen
and
sulphur
have
been
consumed
per year,
which
has
eventually
resulted
in
acid rain throughout the world.
similarly,
ecology
has
been
affected
as
well.
and
considerable
number of species
have been extinct as
the
years
go
by
many
creatures
which
were
common
in
the
past
are
becoming
less
and
less,
even
rare.
the
tibet
antelope,
for
instance, is a good example.
since the
antelopes
of
tibet
have
a
part
of
fur
on
their
body
which
can
be
made
into
a
precious cape, driven by some lawless
dealers
many
villagers
killed
antelopes
excessively and shocking for the large
suns of fortune. because of this, the
number
of
the
antelopes
of
tibet
has
sharply fallen from over one million to
less
than
one
hundred
thousand.
and
what's
more,
the
number
has
now
decreased by 20 thousand per year.
