5. • As coastal areas are developed for human use, dredging, wastewater
discharge, and sediment run-off negatively impact manatee habitat.
• Seagrass beds are destroyed by increased sedimentation.
• Greater human use of waterways means increased entanglement with
fishing gear and increased collisions with boats for manatees.
• Diversion of water for human use means entrapment in culverts and
canal gates for manatees. We know these conditions exist - but what
can we do about it?
• We should seriously consider altering our activities in an effort to
prevent the animal from becoming extinct.
• In the case of manatees and dugongs, we are concerned with the threat
of extinction from over-harvesting and destruction of habitat.
7. ILLEGAL WILDLIFE TRADE
The illegal demand for ivory is the biggest driver of
elephant poaching. Despite a global CITES ban on
international sales of ivory since 1990, tens of thousands
of elephants are killed to meet a growing demand for
ivory products in the Far East. Asia stands behind a
steadily increasing trend in illegal ivory and there are still
thriving domestic ivory markets in Africa.
10. Threats to Survival
Natural predators such as wild dogs, tigers, and leopards take
a toll on Sloth Bears, but their most dangerous predator is
Mankind. Sloth Bears face severe habitat loss as the forests
are being cut down. In addition, poaching for the medicinal
market and use as ‘Dancing’ Bears reduces numbers in the
wild. Bears do not dance. They are made to stand upright
and jump by means of a stick and a painful rope
threaded through their muzzle.
11. A CENTURY AGO THERE WERE 100,000 TIGERS ROAMING
THE FORESTS, SWAMPS, AND TUNDRA OF ASIA. TODAY,
THERE ARE AS FEW AS 3,200 LEFT IN THE WILD. ONLY 7%
OF HISTORIC TIGER HABITAT STILL CONTAINS TIGERS.

13. • Until recently, habitat loss was thought to be the largest single
threat to the future of wild tigers in India. It has now been
established that the trade in tiger bones, destined for use in
Oriental medicine outside India's borders, is posing an even
larger threat. Having decimated their own sources, Far
Eastern traditional medicine manufacturers are now targeting
India for their supply of tiger bones. Poaching of tigers for the
traditional Chinese medicine industry started in northern India
in the mid-1980's.
• Parts from a single tiger can fetch as much as $50,000 on the
black market, making the poaching of these magnificent
creatures very alluring to criminal networks. Claws, teeth and
whiskers are believed to provide good luck and protective
powers. And tiger skins and tiger bone wine are valued as
status symbols.
15. ILLEGAL WILDLIFE TRADE
Poaching of greater one-horned rhinos for their horns
continues to be a major threat. Although there is no
scientific proof of its medical value, the horn is used in
traditional Asian medicines, primarily for the treatment of a
variety of ailments including epilepsy, fevers and strokes.
Asian rhino horn is believed to be more effective than
African horn. Despite protections and bans on international
trade of rhino horn, extensive illegal trade persists
throughout Asia.
17. • Their hearing is however very acute and they also rely mainly
on their well-developed senses of smell to warn them of
approaching danger.
• Rhinos have very poor eyesight and they cannot see
stationery objects even just a few meters away from them.
• Their poor eyesight leaves rhinos very vulnerable against
experienced poachers who are able to approach them to
within a few meters before opening fire.
