Is Earth due for a mass extinction? Earth’s creatures are on the brink of a sixth mass extinction, comparable to the one that wiped out the dinosaurs. That’s the conclusion of a new study, which calculates that three-quarters of today’s animal species could vanish within 300 years.
Why is tiger extinction a problem? These include poaching, Illegal trade of tiger parts, loss of habitat, human conflict, and climate change. Perhaps the most significant factors are poaching and illegal trading of tiger parts. In fact, the extinction of the Caspian and the Javan tiger can be directly linked to hunting.
Why are the tigers important? As a large predator, the tiger plays a key role in maintaining healthy ecosystems. These ecosystems supply both nature and people with fresh water, food, and health. Securing tiger landscapes could help protect at least nine major watersheds, which regulate and provide freshwater for over 800 million people in Asia.
