Almost all zoos have an African and Asian section and most also have a South American section. I'm speaking from my experience visiting zoos in the United States, but I would bet these sections are represented in zoos in other places. Others such as Australian and North American areas are pretty common as well. However, I've never seen an area dedicated to wildlife of Europe. It makes me wonder, is there any zoo in the world that has a section for each of the seven continents?
