Javan rhinoceros is the most endangered of the world’s five rhinoceros species, with an estimated 40-60 animals remaining on the western tip of the Island of Java (Indonesia) in Ujung Kulon National Park. The last member of another tiny population in Vietnam’s Cat Tien National Park was killed by poachers in 2011.
I cannot help thinking when I see all the pictures of Big Cats on Pinterest that it is a ode of farewell. And mostly I don't like the pics because many are from zoo settings as the largest population of Big Cats are caged.
