for our homes and cities.
o We pollute habitats. We illegally
hunt and kill animals. We bring
exotic species into habitats.
oAll of these activities take
resources and habitats away from
plants and animals.

4. A nomadic bird that could reach
speeds in excess of 60mph, the
passenger pigeon was once a
common sight across North
America, from the Great Plains
to the Atlantic Coast. At one point they numbered up
to five billion, making them the most populous species
of bird on the planet.
That was until the arrival of Europeans, who hunted
them on an industrial scale for cheap meat. Tens of
millions were slaughtered each year and the last wild
passenger pigeon was seen in 1901. Cincinnati Zoo was
home to the last captive bird, Martha, which died in
5. Perhaps the most famous
extinct species, the dodo
- endemic to Mauritius -
was also wiped out in
just a few decades. The
first recorded mention of
the flightless bird was by
Dutch sailors in 1598; the
last sighting of one was in
1662. It owes much of its
fame to its appearance in
Alice’s Adventures in Wonderland.
6. This subspecies of the black rhino once roamed sub-
Saharan Africa, but fell victim to poaching. Its
population was in the hundreds in 1980, fell to 10 by
2000, and just five a year later. Surveys in 2006 failed to
locate any and it was declared extinct in 2011. It followed
the extinction of two other black rhino subspecies: the
southern black, around 1850, and the north-eastern
black, in the early 20th century.
7. Extinct since 2000, the
Pyrenean ibex - a subspecies
of the Spanish ibex - was once
common to the Pyrenees but
its population fell sharply in
the 19th and 20th centuries.
The reasons behind its
decline remain unknown. In
2003 it briefly became
“unextinct”, after scientist
managed to clone a female,
but it died minutes after
being born.
8. A subspecies of plains
zebra, with stripes only
on the front half of its
body, the quagga lived in
South Africa. It was
heavily hunted after
Dutch settlers arrived
and found it competing
with domesticated
animals for forage. It was
extinct in the wild by
1878; the last captive
specimen died in
Amsterdam in 1883.
9. A shy, nocturnal animal and
similar in appearance to a
dog (but with a stiff tail and
abdominal pouch), the
Tasmanian tiger was rare or
extinct on the Australian
mainland before the arrival
of the British, but survived
on Tasmania. Hunting,
disease, the introduction of
dogs and human
encroachment all
contributed to its demise
there. The last known
specimen died in Hobart
Zoo in 1936.
10. The largest mammals,
other than whales, to
have existed in the
holocene epoch, the
Steller’s sea cow reached
up to nine metres in
length but was hunted to
extinction in 1768, within
27 years of its
discovery byEuropeans.
11. The woolly mammoth, which reached heights in
excess of three metres and weighed up to six
tonnes, coexisted with early humans, who used its
bones and tusks for making tools and dwellings
and also hunted it for food. Small populations
survived on St Paul Island, off the coast of Alaska,
and Wrangel Island, in the Arctic Ocean, until
5,600 and 4,000 years ago, respectively.
12. Once common to the North Atlantic, including the
coast of Britain, the great auk - like penguins, though
unrelated - was flightless, and clumsy on land, but an
agile swimmer. Demand for its down contributed to its
elimination from Europe, while early explorers used it
as a convenient food source. It has been extinct since
at least 1852.
13. This subspecies of
Galápagos tortoise is widely
considered extinct, with the
last known specimen -
Lonesome George - dying in
2012. A recent trip by Yale
University researchers,
however, suggested that
Isabela Island, the largest of
the Galápagos, could still be
home to the species.
14. Wildlife conservation means the practice of
protecting wildlife; wild plants, animals etc. The
main aims of wildlife conservation in India are to
protect our wild animals, plants for the future
generation. Wildlife is a part of nature that
maintain the balance in the ecosystem. In order to
live a peaceful life on this earth, we need to protect
the wildlife too. Some people are seen harming the
wildlife for their personal benefit. There are lots of
wildlife conservation laws in India but still, our
wildlife is not safe.
