Save the Big Cats
The term Big Cat according to various Organizations includes only the Panthera genus with its five species, namely the tiger, the leopard, the lion, the jaguar, and the snow leopard. But others also include the cheetah and the puma in this group.
They live in countries stretching the globe, from the highlands of Russia, Mongolia, Central Asia and India, through Africa, North, Central and South America.

It can be difficult to picture a world where big cats and humans live alongside one another in harmony. The stigma surrounding big cats with a reputation for being aggressive and dangerous towards humans proves to be a considerable issue hindering big cat conservation. The other main issues are habitat loss and degradation due to expansive land-use change for agriculture, palm oil plantation and transport infrastructure which fragments the landscape, rendering what was pristine habitats now inhospitable for the felines.
Poaching remains another issue facing big cat species. Tigers, leopards, lions, and snow leopards are commonly killed, and their parts sold for the illegal wildlife trade market. The Traditional Chinese Medicine market contributes to a large proportion of the illicit trade, along with demand for the fur to fabricate lavish clothing materials.
Lions and tigers are also infamously bred to accustom them to close human contact for touristic purposes, completely interfering with their instinctive behavior. Once the cubs reach adult age, they are normally moved to open areas where rich hunters pay to have their heads displayed as a trophies (Trophy Hunting), retaining no conservation value.

Given the 2015 IUCN report, of all species of big cats, 5 tigers are considered extinct or regionally extinct, and the remaining species oscillate between Vulnerable (VU), Endangered (EN) and Critically Endangered (CR).
All big cats play a vital role in maintaining ecosystem functionality. If any of the big cat species were to go extinct, as keystone predators, the ecosystem would undoubtedly shift, likely with negative consequences for the diversity and abundance of other species.

To reduce hunting of wild cats, big cats are often kept in protected areas and monitored by rangers. Resources are used to train rangers, fund equipment, and develop intelligence networks to help target the right areas.
To reduce the number of big cats killed by humans who feel their livestock is under threat, prey populations should be protected. Where big cats are living in unprotected areas, conservationists must monitor legal hunting of the prey species; ensuring the big cats have sufficient natural prey might reduce attacks on livestock.
In areas where conflict between humans and big cats has become a serious issue, it may be possible to relocate either humans or big cats. It might also be possible to educate communities living near big cat habitats on practices could help avoid conflict situations.
Campaigning and raising awareness against the use of big cat parts in Chinese medicine can also significantly reduce poaching.
WSO's Activities and Initiatives
The World Sustainability Organization’s Friend of the Earth project provides financial support for the Snow Leopard Trust (SLT), the only organization dedicated to snow leopard species conservation in 5 key countries in Asia. Its habitat coincides with a mountainous and rocky territory, impervious for researchers to explore and protect.
