52. Javan Tiger
The island of Java in Indonesia was home to the Javan tiger until the 1970s. The species was on the smaller scale for a tiger, but that likely didn’t contribute to its extinction.
Habitat destruction and the hunting of these rare tigers is what did it. That, and their primary source of food – rusa deer – suffered disease and died off.
Although conservation efforts were made in the ’20s and ’30s, they sadly were not enough to save the Javan tiger.
