CONSERVATION AND ENDANGERED SPECIES
143
CONTROLLING TRADE
Some animals and plants are taken from the wild for their skins
and other products. Elephants are killed for their ivory tusks.
Colorful flowers are made into pulp to make dyes. The
Convention on International Trade in Endangered
Species (CITES) has lists of hundreds of species,
or kinds, of plants and animals. Selling or
exporting these animals or their products
without a special license is illegal. All whales,
dolphins, and porpoises are on this list;
so are all monkeys, apes, and lemurs.
SNOW LEOPARD
The snow leopard lives high in the mountains of the
Himalayas and Central Asia. In the winter, its fur becomes
thicker to keep out the bitter cold. In the past, the snow
leopard’s winter coat was highly prized by fur traders. Today, the
snow leopard and many other big cats are protected by the CITES
agreement, but they are still hunted illegally in some remote areas.
SNAKE SKIN
The brightly colored objects shown above were once
the skins of snakes and lizards. The skins are dyed
different colors, and then made into all sorts
of leather goods, including bags and shoes.
CAPTIVE BREEDING
One way to help an endangered species
recover its numbers is by breeding it in
captivity. Experts capture a few animals
from the wild, raise them carefully, and
encourage them to breed in captivity.
Later, they release, or reintroduce,
the offspring into a suitable area.
The takahe is a flightless bird that
scientists believed to be extinct until it
was rediscovered in 1948. Eggs from its
nests are hatched in an incubator, and
the chicks are kept warm with tiny
electric blankets. They are fed by
someone wearing a puppetlike glove
that resembles the parent bird.
JACKASS PENGUIN
This flightless sea bird is also called the African or
black-footed penguin. Its numbers have decreased in
South Africa because of water pollution and because
fishing boats catch the fish the penguin eats.
MONK SEAL
Nature reserves have been set up for
the Mediterranean monk seal so that
it will not be disturbed by tourists on
the coasts where it breeds.
HABITAT LOSS
Tropical rain forests are being destroyed at
an alarming rate. Trees are burned or sold
for timber, and the land is farmed or used
for roads, buildings,
and mines. Scientists
believe that many
rain forests contain
kinds of animals and
plants that we have
never seen. For every
plant or creature that is
threatened or extinct,
there may be 100 that
we do not know about.
SUMATRAN
RHINOCEROS
Rhinoceroses are in great
danger of extinction, but
poachers (illegal hunters)
still kill them and sell their horns.
The horns are carved into dagger
handles or powdered into traditional
Chinese medicine. There are fewer
than 100 Sumatran rhinoceroses left in
Sumatra and mainland Southeast Asia.
QUEEN
VICTORIA’S
BIRDWING
The Queen Victoria’s
birdwing was first
collected by scientists in
1855, when they shot it
with guns. Today, this
crustaceans Crabs and other
kinds of butterflies are
declining due to deforestation.
DODO
The dodo was a flightless
bird that lived on islands in
the Indian Ocean. The dodo
was extinct by about 1800.
GOLDEN
LION TAMARIN
Clearing forests
for timber and farmland
endangers the lives of many
monkeys. Many tamarins
and marmosets have been
killed in South America for
the food and pet trade, and
because for a time it was
thought they spread disease.
