Several
animal
species
including
gorillas
(
大猩猩
)
in
Rwanda
and
tigers
in
Bangladesh
could
risk
extinction
if
impact
of
climate
change
and
extreme
weather on their homes is not handled, a UN report showed on Sunday.
Released
during
the
course
of
global
climate
negotiations
in
Durban,
the
report
by
the
United
Nations
Food
and
Agriculture
Organisation
(UNFAO)
shows
how higher temperatures, the rise in sea levels, deforestation and overuse
of
land
have
damaged the
habitats
of
certain
species,
especially
in
Africa.
“Many
ecosystems
have
already
been
affected
by
increasing
population,
historical
and
recent
deforestation,
short?lasting
management
practices
and
even invasive species
，” Eduardo Rojas, assistant director general at the
UNFAO's forestry department, said at the release of the report.
The most affected areas include mountains, islands and coastal areas,
which limit the possibilities for animals to move elsewhere and create new
habitats.
“The
remaining
populations
are
limited
to
very
small
ecosystems.
They have inbreeding (
近亲繁殖
) problems, and at the end these species may
disappear
，” he added.

Other examples of affected animals include elephants in Mali, lions in
Serengeti
and
crocodiles
in
Malawi.
The
report
says
about
20
～
30
percent
of
plant and animal species will be at higher risk of extinction due to global
warming and a significant number of local species may disappear by 2050 as
a consequence. Other consequences could include the spread of invasive
species and infectious diseases, it said.
The
report
urges
more
focus
on
restoration
of
damaged
ecosystems,
especially those key to dealing with climate change such as inland waters,


forests and grasslands. The UNFAO also called for the creation of movement
channels
for
animals
in
areas
where
their
movement
was
affected.
The
organization said while more resources (
资源
) were flowing to biodiversity
conservation,
more
action
at
the
government
and
policy
level
was
needed.
It
also urges local communities to develop projects that ease the effect of
climate change on wildlife, naming eco?tourism activities as an example.

3. To avoid extinction of some animal species, the UNFAO suggested all
the following ways EXCEPT ________.
A. restoring damaged ecosystems
B
．
limiting world population growth
C
．
creating movement channels for animals
D
．

Death
Valley,
one
of
America's
great
national
parks,
is
a
place
of
strange
and
silent
beauty.
As
beautiful
as
this
place
is,
its
name
provides
evidence
of very real danger. Death Valley is a land of beautiful yet dangerous
extremes.
There
are
mountains
that
reach
more
than
3,000
meters
into
the
sky.
There
is
a
place
called
Badwater
that
is
the
lowest
area
of
land
in
the
Western
Hemisphere.
If
there
were
water
there,
it
would
be
86
meters
below
the
level
of the ocean.
Death Valley can be dangerously cold during the winter months. Storms
in
the
mountains
can
produce
sudden
flooding
on
the
floor
of
the
Valley.
The
air
temperature
during
the
summer
has
been
as
high
as
57
℃.
The
sun
can
heat
the ground so that the temperature of the rocks and soil can be as high as
74℃.
The
extreme
heat
of
Death
Valley
has
killed
people
in
the
past.
It
will
continue to kill those who do not honor this extreme climate. Death Valley
does not forgive those who are not careful.
Death Valley is a good example of the violence of nature. It contains
evidence
of
several
ancient
volcanoes
that
caused
huge
explosions.
Evidence
of one of these explosions is called Ubehebe Crater. The explosion left a
huge hole in the ground almost a kilometer and a half wide.
In
many
areas
of
Death
Valley
it
is
easy
to
see
where
the
ground
has
been
pushed
up
violently
by
movement
deep
in
the
Earth.
This
movement
has
created
unusual
and
beautiful
rock
formations.
Some
are
red.
Others
are
dark
brown,
gray, yellow or black. Other areas of rock look as if some huge creature
violently
broke
and
twisted
the
Earth
to
create
unusual,
sometimes
frightening shapes.
