Celebrating World Wildlife Day

Today is World Wildlife Day, the UN-sponsored tribute to efforts that protect the plants and animals that make our world so special. This year's WWD theme is 'recovering key species for ecosystem restoration' – key species like the greater one-horned rhinoceros you see here in northeastern India's Kaziranga National Park. These unique creatures have staged a remarkable comeback from the verge of extinction in the early 20th century when their numbers had dwindled to a precarious low of around 200 animals. But with the concerted efforts of Indian and Nepalese wildlife authorities, the population of greater one-horned rhinos has slowly built back up to around 3,700 today.
