What do pandas,tigers,whales,lions and wild camels have in common?
What
do
pandas,
tigers,
whales,
lions
and
wild
camels
have
in
common?
They
are
all
endangered(
濒临灭绝的
).Here are the reasons.
Hunting
:For centuries,people hunted elephants for their tusks,
killed tigers for their fur,and
caught many other animals for their meat.
Foreign
animals
:
In
1505,
some
people
discovered a
beautiful
island
named
Mauritius
in the
Indian Ocean.People brought dogs,pigs,monkeys and rats with them,but this was bad news for dodo
birds.The birds did not have
natural enemies (
天敌
) before.They ate fruit that fell from trees and
built their house on the ground.But when people came,dodo birds were in big trouble
—
men killed
them for their meat,and the new animals broke their homes and ate their eggs.The number of dodo
birds became smaller and smaller and finally
extinct
.The last dodo bird was killed in 1681.
Loss
of
living
space
:
People
cut
down
forests
for
farming
and
building
houses.
People
build
dams
(
水坝
)
to
make
sure
they
have
enough
water.
While
we
make
our
lives
comfortable,
other
animals have less and less space.
