The Amazon is an obvious one with all the diversity of wildlife there. Despite all the exploration that has been done there a lot still is not know about the jungle. Medicines continue to be found and many different species exist which few people know about. I was reading about the world's largest freshwater fish. Pink, fresh-water dolphins are another thing that is unique to the Amazon.
Mountainous regions. Mountain areas in general contain the most diversity of life on the planet. Since they do not have the same lushness as the jungles at lower elevations it is easy to miss this fact.
The Congo. I recently read a piece in the Nation about how the Congo rainforest is the most intact jungle in the world. It is also the second-largest rainforest. Gorillas still roam these wilds.
Indonesia and the surrounding area. Both Australia and Malaysia claim that their rainforest is the oldest in the world. Maybe both are right if they were once part of a larger area or are to be considered together. Indonesia and the surrounding lands have incredibly diverse and unique flora and fauna. The durian fruit and the mangosteen come from this part of the world. So do the Birds of Paradise with their elaborate mating rituals.
Other tropical parts of South America. There is a lot of diversity in South America from the Choco rainforest on the Pacific Coast to Angel Falls in Venezuela.
Africa. Other than the Congo and Mount Kilimanjaro which has its own rainforest on the side of the mountain the savannas have lions, wildebeests, giraffes and many other exotic animals. The diversity in tribal culture is also something which we can learn a lot from. Watermelons are originally from this continent as well.
Central America. Because this area connects with both North and South America and is tropical as well as mountainous this area has an incredible diversity of life. The narrow strip of land concentrates the species and thus makes it easier to see a lot within a small area.
Deserts. Not so much in the far north but more in tropical or subtropical regions. These areas gives us many clues as to how life adapts to limited water. The Bushmen are able to live full lives in the Kalahari despite the limitation of water. In Arizona huge cacti form that seem to defy the elements.
Coral reefs with their beautifully colored fish are stunning to observe
Subtropical regions such as Florida are unique in their own way. Florida has a swamp that is unlike any other in the world and the unusual plants and animals take a while to learn. Even the pines have many different species represented.
