Pantanal

The Pantanal is one of the world's largest continuous wetlands. It is spread out about 60,000 square miles in Brazil, Bolivia, and Paraguay, making it ten times larger than the Everglades. It's believed to contain more species of birds than all of Europe, 50 different types of reptiles, and hundreds of species of fish.

Now the Pantanal, like with many other wetland regions, is under threat from careless farming practices and poor sewage treatment.
