Wetlands are where earth and water meet.
They are almost as old as the planet itself, and are home to some of the richest biodiversity on Earth. They are to be found all over the world from the tropics to the frozen plains and are as crucial to the planet 's well-being as any other finely balanced part of nature. They are also among the most beautiful places on Earth, and have inspired artists, travellers, poets, and photographers for generations. Which is hardly surprising - wetlands are host to a spectacular array of wildlife ranging from kingfishers to caimans, herons to hippos, and an abundance of rare plantlife and exotic marine creatures. Wetlands vary enormously in size.
