On the International Day for Biological Diversity, join us to travel around the world's national parks and reserves across seven continents: From the "national treasure" giant pandas in China's Shaanxi Qinling to koalas and kangaroos in Australia, from the towering redwoods in America to the Royal Botanical Garden in Britain, from lions and elephants in the African savannah to penguins and seals on the Antarctic ice. Let's walk into the wild, and get to know our friends in nature!
