2. Animal extinction
Extinctions of species are
natural in the planet's history,
but in recent history, man has
had direct responsibility for the
extinction of many animal
species.
3. The Tasmanian wolf
• The Tasmanian wolf or Tasmanian tiger was a
carnivorous marsupial native to Australia. It looked
like a large dog, which could be measured 180 cm
in length including the tail of 60 cm. In terms of
weight, could reach 30 kg.
The Tasmanian wolf became extinct in the
twentieth century, the last issue of on record died
in the Hobart Zoo on September 7, 1936. There are
several reasons for their extinction, competition
with foxes and wild dogs brought to Australia by
Europeans, hunting by farmers who were blamed
for the death of his sheep.

5. The bucardo
• The Bucardo was a kind of endemic Pyrenean
ibex. It differed from other species by its long,
thick hair, and their antlers longer than all other
Iberian goats.
Since the second half of the nineteenth century
many hunters from all over Europe traveled to
the Pyrenees to capture this goat, just by having
the impressive antlers of this species. The last
Bucaro, a female, died in January 2000 when a
tree fell on her and crushed his skull.

7. Quagga (Equus quagga quagga)
• Quagga (Equus quagga quagga)
This species of zebra in South Africa is
completely extinguished in about 1870. He
had a reddish brown coat (no stripes) on the
back and hindquarters, and black stripes on
the face, neck, sides and mane, as have the
other zebras. The belly and legs were
completely white. Such a coat made in 1788
that it be classified as a separate breed.
8. • The quaggas were hunted by early Dutch settlers,
for their meat and skin. In the mid-nineteenth
century thousands of copies were killed as part of
a plan to exterminate wild animals. This policy
was designed to take advantage of the grazing
lands where quaggas to feed livestock. The
population of these animals declined rapidly, and
the August 12, 1883 the last quagga died in
captivity living in Amsterdam Zoo, quashed the
subspecies.

10. Baiji or Chinese River Dolphin
• El baiji, también llamado Delfín chino de río, es una especie
de cetáceo odontoceto de la familia Iniidae. Es un delfín de
río encontrado sólo en el río Yangtze (China). Apodado "la
diosa del Yangtze" en China, se presume extinto a fines del
2006 luego de que una expedición no pudo encontrar
ejemplares en el río. Sin embargo, en 2007, un baiji fue
avistado por un vecino de la provincia china Anhui, llamado
Zeng Yujiang. Las imágenes fueron revisadas en el Instituto
de Hidrobiología de la Academia de Ciencias China quienes
confirmaron su autenticidad. Pero en los meses de Mayo-
Junio de 2008, se ha vuelto ha declarar al baiji,
completamente extinto. Su extinción se debe a la
industrialización de China, la draga y el uso intensivo del rio
para la pesca, transporte y energía eléctrica, el tráfico fluvial
y muchos otros factores más.

12. The magnitude of the problem
• Low levels of animal welfare are worldwide,
affecting a wide variety of animals. There are
examples of many causes, including our
growing demand for meat, the impact of
natural disasters and lack of understanding on
how to care for animals. We need a unified
agreement between governments to protect
animals from cruelty and neglect in the future.
Billions of animals raised intensively to
produce food. These animals have little room
to move or behave naturally. Most never have
contact with fresh air or daylight nor guarantee
a humane death.
13. Wild animals are cruelly hunted and
killed for commercial purposes. Their
skins, tusks, bones and other parts are
sold legally and illegally to make
clothes, accessories and medicines.
They are also abused in the name of
sport and entertainment.
14. • There are about one billion stray cats
and dogs in the world. Sometimes they
are feared and persecuted by people
terrified by the possibility of contracting
diseases such as rabies. Local authorities
often do not have laws on the humane
treatment of these animals, so
poisoning, and electrocution shots,
which often cause a slow and painful
death, are common.
