What Are the Seven Wonders of the Natural World?

SUMMARY

• Stunning Natural Phenomena: The Seven Wonders of the Natural World include awe-inspiring natural sites renowned for their breathtaking beauty and scale.
• Diverse Environments: These wonders showcase a range of environments, from vast waterfalls and rainforests to unique volcanic islands and subterranean rivers.
• Ecological and Cultural Significance: Each wonder is noted for its ecological importance and cultural significance, highlighting their roles in both nature and human heritage.

We all know about the Seven Wonders of the World, an ancient list once compiled to celebrate the incredible achievements of human civilization. More recently, a modern-day Swiss company called the New7Wonders compiled a new list of World Wonders. But did you know the same company also put together a list of the Seven Wonders of the Natural World, as voted for by 500 million members of the public in 2011? The public chose these seven locations for their breathtaking beauty, natural diversity, ecological importance, location, and historical legacy. (Bearing in mind this is one of several lists of natural wonders that exist in the world.) Read on to learn about these must-see natural hot spots for the most intrepid explorers.

1. Iguazu Falls, Argentina and Brazil

Iguazu Falls are a series of waterfalls on the Iguazu River. They border the Argentine province of Misiones and the Brazilian state of Paraná, near the city of Curitiba. Incredibly, Iguazu is the largest waterfall system in the world, at 82 meters high and an incredible 2,700 meters wide. This natural phenomenon is a true sight to behold, and UNESCO named it a World Heritage Site in 1984. The surrounding landscape is equally impressive, forming two areas of Natural Park on either side of the river.

2. Table Mountain, South Africa

The aptly named Table Mountain is a flat-topped mountain that overlooks Cape Town in South Africa. Such is its national importance, the mountain appears in the Cape Town flag, and other government insignia. The mountain’s distinctive, level tip covers an area of around 3km. From here, dramatic cliffs drop down its sides. In colder times of year, the mountain’s flat top collects orographic clouds. Locals sometimes refer to them as a “tablecloth.” Legend has it the white puffs are the result of a smoking competition between the Devil and a local pirate called Van Hunks.

Ha Long Bay in Quảng Ninh Province, Vietnam has long been a tourist attraction due to its fascinating prehistoric biosystem. Amazingly, the bay contains a vast array of around 1,960–2,000 islets, or mini-islands. They have been steadily growing out of limestone over the past 500 million years. Historians even think prehistoric human beings once lived here, many thousands of years ago. Today, the site is also home to 14 endemic floral species and 60 endemic faunal species, making it a special, self-contained site where nature has been taking its course for millennia.

4. Amazon River and Rainforest

Almost everyone must have heard of the Amazon jungle. So, it’s little wonder that the Amazon Rainforest and River were voted high on the list of seven natural wonders of the world. This vast stretch of land spans 6.7 million square kilometers and covers 9 different nations: Bolivia, Brazil, Colombia, Ecuador, Guyana, Guyana, Peru, Suriname, and Venezuela, making it the largest forest in the world. The Amazon River running through it contains the largest discharge of water in the world. The Amazon plays such a vital role in the preservation of the planet, that ecologists call it “the lungs of the world.”

5. Jeju Island, South Korea

Jeju Island in South Korea is a volcanic island made entirely from volcanic eruptions around 2 million years ago, during the Cenozoic era. This means its craggy surface is predominantly made up of basalt and lava. Its surface area covers 1,846 square kilometers, making it the largest island in South Korea. Popular attractions on the island are Hallasan Mountain, a dormant volcano rising 1,950 m above sea level, and Manjanggul Lava Tube, an 8 km long lava tube that brave visitors can walk part of the way along.

Komodo Island is one of a great many islands making up the Republic of Indonesia. The island is renowned for being the home of the Komodo dragon, the world’s largest lizard, who takes his name from the island. At 390 square kilometers, this relatively small island has around two thousand inhabitants who share their habitat with the dangerous reptiles.

7. Puerto Princesa Subterranean River, Philippines

Puerto Princesa Subterranean River, also known as the PP Underground River, runs through a protected area of the Philippines called Puerto Princesa Subterranean River National Park. The river runs through a domed cave where many marine creatures and bats live. Brave explorers can only travel so far inside the underground cavern due to the risk of severe oxygen deprivation. It is this terrifying, yet magical quality that makes PPU Underground River a star player in the seven wonders of the natural world.

Embracing and Preserving the Earth’s Natural Masterpieces

From the heights of Iguazu Falls to the Puerto Princesa Subterranean River, these natural wonders of the world are certainly beauties to behold. They are made even more culturally significant and special because they were voted on by the public, meaning they represent the natural sights people around the world truly believe are wonders. Beyond beauty, these natural sights are important for maintaining biodiversity, ecological balance, and overall environmental health. It is crucial to take measures to protect these sights, and other parts of the world’s breathtaking natural environments, to ensure sustainability and longevity.
