The Amazon Rainforest, also known as Amazonia, the Amazon jungle or the Amazon Basin, encompasses seven million square kilometers (1.7 billion acres), though the forest itself occupies some 5.5 million square kilometers (1.4 billion acres), located within nine nations. The Amazon represents over half of the planet's remaining rainforests and comprises the largest and most species-rich tract of tropical rainforest in the world. The Amazon River is the largest river in the world by volume, with a total flow greater than the top ten rivers worldwide combined. It accounts for approximately one-fifth of the total world river flow and has the biggest drainage basin on the planet. Not a single bridge crosses the Amazon
2.Angel Falls
Angel Falls is the highest waterfall in the world, at 1,002 m, and is located in the Canaima National Park in Bolivar State, along Venezuela’s border with Brazil. It is more than 19 times higher than Niagara Falls. The uninterrupted descent of water falls 807 m.
The Bay of Fundy is renowned for having the highest tides on the planet (16.2 metres or 53 feet). One hundred billion tonnes of sea water flow in and out of the Bay of Fundy twice daily – more water than the combined flow of all the world’s fresh water rivers. Fundy’s extreme tides create a dynamic and diverse marine ecosystem. The Bay is renowned for its coastal rock formations, extreme tidal effects (vertical, horizontal, rapids and bores) and sustainable coastal development. It is also a critical international feeding ground for migratory birds, a vibrant habitat for rare and endangered Right whales, and one of the world’s most significant plant and animal fossil discovery regions. The Bay of Fundy is located between the Canadian provinces of New Brunswick and Nova Scotia on North America’s east coast.

Off the western shores of Abu Dhabi, in the United Arab Emirates, lies a unique natural treasure, wild and undisturbed by human activity: Bu Tinah Island. Bu Tinah’s thriving ecosystem forms a unique living laboratory with key significance for climate change research. An undisturbed paradise, Bu Tinah has much to teach mankind about environmental protection and survival. This distinctive natural habitat has shallow waters, seagrass beds and tall mangroves, set amid extensive coral reefs. It hosts beautiful and endangered marine life. Seabirds, including flamingos and osprey, various species of dolphins and the critically endangered hawksbill turtle live in Bu Tinah. The island’s waters host the world’s second-largest population of dugong, a large marine mammal that is threatened worldwide. Bu Tinah Island, rich in biodiversity, lies within the Marawah Marine Biosphere Reserve - the region's largest marine reserve. Its protection and survival must be ensured.

Jeita Grotto is a compound of crystallized caves in Lebanon located 20 km north of Beirut in the Valley of Nahr al-Kalb (Dog River). This grotto is made up of two limestone caves, upper galleries and a lower cave through which a 6230 m long river runs. Geologically, the caves provide a tunnel or escape route for the underground river. In this cave and galleries, the action of water in the limestone has created cathedral-like vaults full of various sizes, colors and shapes of stalactites and stalagmites, majestic curtains and fantastic rock formations. The total length of the cave is more than 9000 m and there is one among the biggest stalactites in the world hanging 8,20 m.
