庆祝世界野生动物日(Celebrating World Wildlife Day)

今天是世界野生动物日，联合国赞助的纪念活动旨在保护使我们的世界如此特殊的动植物。今年的WWD主题是“恢复生态系统恢复的关键物种”——如印度东北部卡兹兰加国家公园中的大独角犀牛等关键物种。这些独特的生物在20世纪初从濒临灭绝的边缘显著卷土重来，当时它们的数量已经减少到大约200只动物的危险低点。但在印度和尼泊尔野生动物管理部门的共同努力下，大独角犀牛的数量已缓慢增加到今天的3700头左右。

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.
