The top 10 most endangered species are the polar bear, Bengal tiger, corals, kangaroo, whales, penguins, turtles, orangutan, elephant, and albatross. The polar bear could disappear within 50 years due to shrinking Arctic ice sheets. 80% of corals may disappear within decades. Climate change threatens kangaroos, whales, penguins, orangutans and albatrosses. Commercial fishing, hunting, and habitat destruction endanger turtles, elephants and albatrosses.

1. Top 10
Endangered species

2. The Polar Bear
The first in our list is occupied by the
polar bear as a species could
disappear within 50 years if, as
expected, continue to shrink the
Arctic ice sheets.

3. The Bengal Tiger
The second animal is most endangered
Bengal tiger that lives in mangrove
between Bangladesh and India. The
Bengal tiger or Indian is, after the Siberian
tiger, the second largest species of tiger in
the world.

4. The Coral
In the third place on the list include
corals, of which 80% may disappear
within decades. Different reports
show that a third of coral reefs are
endangered.

5. The Kangaroo
Due to global warming, the most
emblematic species of Australia,
kangaroo, could disappear within a
few years.

6. The Whale
Commercial hunting and for
"research" vessel traffic, pollution of
the seas, and climate change
phenomena such as "El Niño" or "La
Niña" threaten the lives of whales in
the world.

7. The penguin
The four main species of penguins
that live in Antarctica are threatened
with extinction because of global
warming.Another serious problem is
oil spills, for cargo vessels, which
extend around the globe.

8. The Turtle
Commercial fishing and the
Destruction of nesting areas on
beaches threaten to eliminate a
species that takes 150 million years
to inhabit the Earth.

9. The Orangutan
The eighth position is occupied by the
orangutan. In two inhabited islands of
Indonesia this ape, climate change
causes increased rainfall during the
rainy season and the dry season
fires.

10. The Elephant
While climate change and
deforestation are guilty of the species
on this list, the main enemy remains
his elephant ivory.

11. The Albatross
19 of the 21 species of this animal are
threatened worldwide. Two species are
"critically endangered", the "Albatros
Amsterdam", natural Southern
Hemisphere, and the "Albatross Catham
Islands’’.
