For centuries, elephant has been an indispensable part of Asian culture.
Especially in Thailand, elephant once was treated as the sacred symbol,
but as time went by, elephant was domesticated in the zoo. Thousands of
tourists rode elephants and enjoyed the project, but they did not
realize what they did to these poor
video was shot by a foreign guy, who exposed what the elephants suffered
during the training. The small babies were forced to be apart from their
mothers. Once the elephants refused to do what the trainers wanted them
to do, they would be punished by not getting food or beaten. How cruel
it was. The public saw the video and many of them asked the zoo to stop
providing the activity of riding
more people realize the hurt that elephant gets when they are enjoying
riding it, they stop to join this project, which helps to protect the
animal. Then the situation changes. Zoos start to give up domesticating
elephant, instead, they let tourists feed it. It is a win win situation.
Animals enjoy the freedom, while human being can watch them. What a

Africa’s wildlife is in a constantstate of danger.

Between 2009 and 2015,TanzaniaandMozambiquelost more than
their elephants, many of them topoaching forivory
The decline has propelledAfrican vulture
who feed onelephant carcasses, toward extinction too. And attempts
ivory smuggling haven’t helped thedwindling elephant population. InSouth
Africa, rhinos are aprized poaching
for their horns. The attempts tokeep poachers at bay having failed, some
conservationists have proposed theexpensive alternative ofairlifting
from poaching sites.

Uganda, which remains“heavily
the illegal ivory trade accordingto the monitoring body CITES, is now
testing a more direct way to crack down onthe illegal hunters before
they even get to the animals. Using ProtectionAssistant for Wildlife
Security (PAWS), a technology combining machine learningand game theory,
researchers can predict where poachers may attack and tellrangers where
to patrol.

“The basic idea is that youhave limited resources, you can’t be
everywhere all the time,”UniversityofSouthern Californiaprofessor
MilindTambe, who’s leading the initiative, told Quartz. “Where and when
should you dopatrol?”

To make their predictions,researchers studied 12 years worth of data
collected by rangers, from 2003 to2015, provided by the Wildlife
Conservation Society. These included reports ofpast attacks, snare
placements, and other illegal activities. The data aren’t perfect,says
Tambe: Rangers don’t patrol the entire park, so it’s hard to get
acomplete picture. But it’s enough to let a machine learning algorithm
makeintelligent guesses about where poachers will strike in future.

When creating patrol routesfor rangers, “we want to randomize our
patrols because we ourselves don’t wantto become predictable to the
poachers,” Tambe said. That’s where game theorycomes in. It uses
mathematical models to evaluate how rational human beingswould act, to
then suggest routes that won’t be easily predictable.

The US Coastguard,Transportation Security Administration (TSA), the
Federal Air Marshals Service,LA Sheriff’sDepartment, and other
organizations have been using Tambe’s AI-game theorycombination
technology to randomize their patrols since the early 2000s, hesays. The
concept was tailored for wildlife preservation in 2014 and deployedfor
testing inMalaysiain mid-2015. The current large-scale Ugandan tests
inQueenElizabethNational Parkare backedby US organizations like the
National Science Foundation and the Army ResearchOffice.

Rangers using PAWS inUgandahavefound 10 antelope traps and elephant
snares in the past month, “a far betterscore card than they could
usually expect,”Reuters
As robust as the technologymight be in theory, factors like poor mobile
internet connections can get inthe way of communicating the results from
PAWS that are used to direct rangers’routes. And there’s another threat:
Armed poachers are quick topoint their
the rangers.
