The Pantanal is the largest continental wetland in the world, covering 130,357 square kilometers in Brazil, Paraguay and Bolivia. Its 175 piranha-infested rivers are home to 10 million cayman crocodiles and 600,000 capybara, the worldâ€™s largest rodents. 50 species of reptiles, 190 mammal species including jaguar and howler monkeys, more than 1000 species of butterflies, and 658 bird species live in the area. <p>A UN report on the wetlands says 85 percent of the rich, fragile ecosystem could be wiped out if the earthâ€™s temperature rises by three or four degrees Celsius. <p>The area is also under threat from industrial development. The region has some of the largest reserves of magnesium and iron ore in the world and the stateâ€™s governor is proposing the building of a steel mill and the fivefold increase of iron ore extraction.
