Pantanal is the world’s biggest wetland, it is larger than 29 US states and at least nine European countries.This pristine environment in South America supports a rich variety of wildlife and plants, while its enormous water reserves are vital for the 8 million people who depend on the Pantanal’s fresh water, fish, climate control and tourism.Wetlands—places where the land is covered by water, either salt, fresh, or somewhere in between—cover just over 6% of the Earth’s land surface. Sprinkled throughout every continent except Antarctica, they provide food, clean drinking water, and refuge for countless people and animals around the world.
