Lions, Tigers, and Bears—Oh My!
Body
The giant panda, orangutan, Sumatran Elephant, and the Sunda Tiger all have something in common: they’ve joined a growing list of animals on the brink of extinction. A newly published study in the Proceedings of the National Academy of Sciences lists 515 animal species with fewer than a thousand individuals remaining. There are 3 billion fewer birds in the skies in North American than in 1970, and scientists project that up to 30 percent of America’s wildlife species are at risk of extinction within decades. Overall, the report is grim: We’re in the midst of the sixth mass extinction ever experienced by our planet, accelerated by the explosion of the human population in the last 100 years.
