The New Seven Wonders of the Modern World: Great Wall of China Built Between the 5th Century B.c. And the 16th Century, the Great Wall of China is a Stone-and-earth Fortification Created to Protect the Borders of the Chinese Empire From Invading Mongols. The Great Wall is Actually a Succession of Multiple Walls Spanning Approximately 4,000 Miles, Making It the World's Longest Manmade Structure. The Roman Colosseum (Rome) Built Between 70 a.d. And 80 a.d., It Was in Use for Some 500 Years. The Elliptical Structure Sat Nearly 50,000 Spectators, Who Gathered to Watch the Gladiatorial Events as Well as Other Public Spectacles, Including Battle Reenactments, Animal Hunts and Executions. Earthquakes and Stone-robbers Have Left the Colosseum in a State of Ruin, but Portions of the Structure Remain Open to Tourists, and Its Design Still Influences the Construction of Modern-day Amphitheaters, Some 2,000 Years Later. Christ the Redeemer Statue (Rio De Janeiro) Christ the Redeemer Statue Has Been Looming Over the Brazilians From Upon Corcovado Mountain in an Awe-inspiring State of Eternal Blessing Since 1931. The 130-foot Reinforced Concrete-and-soapstone Statue Was Designed by Heitor Da Silva Costa and Cost Approximately $250,000 to Build, the Statue Has Become an Easily Recognized Icon for Rio and Brazil. Machu Picchu (Peru) Machu Picchu, an Incan City of Sparkling Granite Precariously Perched Between 2 Towering Andean Peaks, is Thought by Scholars to Have Been a Sacred Archaeological Center for the Nearby Incan Capital of Cusco. Built at the Peak of the Incan Empire in the Mid-1400s, This Mountain Citadel Was Later Abandoned by the Incas. The Site Remained Unknown Except to Locals Until 1911, When It Was Rediscovered by Archaeologist Hiram Bingham. Taj Mahal (Agra, India) A Mausoleum Commissioned for the Wife of Mughal Emperor Shah Jahan, the Taj Mahal Was Built Between 1632 and 1648, the White Marble Structure Represents a Number of Architectural Styles, Including Persian, Islamic, Turkish and Indian. The Taj Mahal Also Encompasses Formal Gardens of Raised Pathways, Sunken Flower Beds and a Linear Reflecting Pool. Chichen Itza (Yucatan Peninsula, Mexico) The Genius and Adaptability of Mayan Culture Can Be Seen in the Splendid Ruins of Chichen Itza. This Powerful City, a Trading Center for Cloth, Slaves, Honey and Salt, Flourished From Approximately 800 to 1200, and Acted as the Political and Economic Hub of the Mayan Civilization. The Most Familiar Ruin at the Site is El Caracol, a Sophisticated Astronomical Observatory. Petra (Jordan) Declared a World Heritage Site in 1985, Petra Was the Capital of the Nabataean Empire of King Aretas the Fourth, the Members of This Civilization Proved to Be Early Experts in Manipulating Water Technology, Constructing Intricate Tunnels and Water Chambers, Which Helped Create an Pseudo-oasis. A Number of Incredible Structures Carved Into Stone, a 4,000-seat Amphitheater and the El-deir Monastery Have Also Helped the Site Earn Its Fame.

Deep Sea Gigantism (abyssal gigantism) is defined as the the tendency for deep-sea animals to grow to much larger sizes than their shallow water relatives. Biologists still aren’t certain why it is that some abyssal creatures grow to these immense sizes, for we have still only scratched the surface of discovery in the deep. But there are many theories, which may help to shed light on this mystery of the oceanic deep. A brilliant example to show that deep sea fauna does indeed follow this rule, is the mollusk group, gastropods, which includes slugs and snails. In the deep, many species that are near symmetrical to shallower varieties, grow to be huge. The deep sea isopod belongs to a group that rarely grows larger than a few inches in the shadows, but down here they can grow to half a metre in length, and weigh approximately 1.7 kilograms. This variety, the giant isopod, is found in the deep, cold waters of the Pacific Ocean, the Atlantic Ocean, and the Arctic Ocean.

The earliest lists of Seven Wonders of the Ancient World were made more than 2,000 years ago by ancient Hellenic tourists. Except for the Great Pyramid of Giza those wonders no longer exist. They were destroyed by earthquakes, fires and in one case by an angry mob. Many other lists of amazing structures have been made since then. Here’s a look at our list of the greatest man-made wonders of the world

Oceanic Islands make up a sixth of all land on Earth. In the Pacific alone, more than 25,000 islands are scattered amidst the endless blue. From Hawaii's rocky mountains, to coral atolls of the Maldives, each hosting unique communities of life and species found nowhere else on Earth. Ecosystems that would not exist if not for the powerful forces that pulled these mighty rocks from the abyss. Volcanism, and tectonics.

Massive glaciers, staggering mountains, plains dotted with wild animals: We sure live in a big, beautiful world. And while pinpointing all of Mother Nature's greatest hits could take a lifetime, we think these out-of-this-world landscapes and awe-inspiring wonders, from Arizona to Antarctica, need to move to the very top of your travel list.

Deep Sea Brine Pools appear to be biological dead-zones in the ocean, and yet an astounding abundance of ocean life can be found lining the shores of these toxic lakes. Mussels, hagfish, crabs and even sharks frequent these isolated hotspots to hunt. A community of uniquely adapted organisms is able to thrive on the brine pool shore; in a similar fashion to the life that inhabits deep sea hydrothermal vent communities, we find organisms capable of chemosynthesis, as well as other organisms preying on them – all interacting and existing on the borders of a toxic pool of brine. As the energy here is largely supplied by chemosynthesis, rather than sunlight, brine pools also mirror hydrothermal vents in demonstrating how the extreme deep sea ecosystem is unique in the ways in which it supports life. There are no photosynthesising primary producers converting sunlight to energy, as the light of the sun cannot reach these depths. Instead, energy is supplied by the Earth itself.

As the tide recedes along the shores, it uncovers a truly alien world of rock pools. At first look, the landscape presents little more than a barren, lifeless stretch of thick mud and rotting seaweed, strewn with boulders. But these features come together to create a unique habitat. Twice a day, miles of sand, gullies, reefs and rock pools are exposed, bringing into view a wealth of rarely seen marine life. Here, the sparse isolated pools open a window on the many conflicts that these creatures must content with in order to survive. Each rock pool is a tiny but complex ecosystem, home to crabs, shrimps, and all manner of incredible creatures.

The wonderful world of whales and dolphins. Below the waves lies a world of giants. Out in the open ocean, whales and dolphins are well-suited for to a life of wandering, traversing thousands of miles each year in search of krill blooms or breeding grounds. Together, these colossal mammals belong to the infraorder cetaceans. A name with roots in Greek, from ketos, meaning ‘a large sea creature’. But despite their size, cetaceans are elusive creatures, spending most of their lives underwater and in remote areas far out to sea. Let’s shine a light on the wonderful world of these marine mammals.

The Mariana Trench sits like a crescent-shaped dent in the floor of the Pacific. A 2,550 km long, 69 km wide fracture that plummets down into a pure black void of the Hadal Zone. At the bottom, it hosts the deepest known location on Earth. The Challenger Deep, 11,033 metres or 36,200 feet beneath the waves. The trench itself is but one part of a global network of deep scars that cut across the ocean floor. Features that formed from a process called subduction. In the case of the Mariana Trench, the western edge of the Pacific Plate was thrust beneath the smaller Mariana Plate to the west, creating the deep fracture. Molten material then rose through volcanoes near the trench, building the nearby Mariana Islands.

Explore the underwater world of Raja Ampat in the Coral Triangle across four feature length 4K films, filmed over 30 years by underwater videographer Edi Frommenwiler. The Coral Triangle is one of the most biodiverse places on Earth, hosting reefs and atolls that support abundant life, from the beautiful and charismatic, to the weird and wonderful.
