10 Natural Wonders to See Before They Disappear

This article caught my eye, not only because I would like to see these treasures for myself someday, but also because I didn’t realize that these places are under threat.

You’ve heard the grim timelines: if warming continues, the Great Barrier Reef will be bleached by 2030; glaciers in the Swiss Alps, on Mt. Kilimanjaro, and in Glacier National Park will disappear in under 40 years; and Arctic ice melt will leave the North Pole bare and polar bears extinct. The immediacy of these timelines prompts flocks of curious eco-tourists to travel to environmentally fragile areas. Tourism is both bane and boon: it can add strain to already distressed areas, but it can also provide income, which in turn can help preserve these wonders. In time for Earth Day, we spotlight 10 areas under threat—some lesser known than others—that can still be visited responsibly.

Belize Barrier Reef

One of the most diverse reef ecosystems in the world is home to whale sharks, rays, and manatees, as well as sturgeon, conch and spiny lobsters.

The Threat: Like the Great Barrier Reef in Australia, the Belize Barrier Reef leads a tenuous existence. A section of the nearly 700-mile-long Mesoamerican Reef that reaches from Mexico to Honduras, the Belize reef suffered a severe bleaching in 1998, with a loss of 50 percent of its coral in many areas, including much of its distinctive staghorn coral. Since the bleaching, its decline has continued, due to global warming of the world’s seas, agricultural pollution, development, and increasing tourism, which has given rise to more coastal development and an invasion of cruise ships.

The Congo Basin

Tropical rainforests like the Congo Basin produce 40 percent of the world’s oxygen and serve as a vital source of food, medicine and minerals.

The Threat: At more than 1.3 million square miles, the Congo Basin has the world’s second-largest rainforest, after the Amazon’s. According to the UN up to two-thirds of the forest and its unique plants and wildlife could be lost by 2040 unless more effective measures are taken to protect it. Extending across six nations, ten million acres of forest is degraded each year due to mining, illegal logging, farming, ranching, and guerilla warfare. Roads cut by loggers and miners have also enabled poachers and bushmeat hunters to prey on endangered animals like mountain gorillas, forest elephants, bonobos, and okapis. As the forest shrinks, less carbon dioxide is absorbed, and rain decreases, adding to climate change.

The Dead Sea

It’s the lowest spot on earth (1,312 feet below sea level), has 10 times more saline than seawater (so humans float like corks), and is believed to contain therapeutic minerals.

The Threat: In the last four decades, the Dead Sea has shrunk by a third and sunk 80 feet—13 inches per year!—stranding formerly seaside resorts and restaurants nearly a mile from shore. The Jordan River is the lake’s sole source, and as surrounding countries increasingly tap its waters, little reaches the Dead Sea, which could disappear within 50 years. Further pressure is put on the sea by the cosmetic companies and potash producers who drain it for minerals. One proposed solution is the controversial Red-Dead Canal, channeling water 112 miles from the Red Sea, but its environmental impact could be negative (some worry that it would increase seismic activity in the region).

The Everglades

This 2.5 million–acre wetland encompasses cypress swamps, mangroves, sawgrass and pine savannahs. It’s the only place in the world where crocodiles and alligators share territory.

The Threat: A host of dangers are putting this fragile wetland at risk: pollution from farms, invasive species, and encroaching development, not to mention the fact that 60 percent of the region’s water is being diverted to nearby cities and farms. As a result, The Everglades is now half the size it was in 1900. Worse, this is the sole habitat of the Florida panther, and there are less than 100 of the creatures left in the wild. These big cats may be completely lost within the next 40 years as their habitat disappears (they’re not alone, either—at least 20 species in the Everglades are endangered, including turtles, manatees, and wading birds).

Madagascar

More than 80 percent of Madagascar’s flora and fauna are found nowhere else on Earth, thanks to millions of years of isolation in the Indian Ocean off of Africa.

The Threat: If nothing is done to save the world’s fourth-largest island, its forests will be gone in 35 years (once 120,000 square miles, they’re now down to 20,000), and their unique inhabitants along with them. Forest ecosystems are being destroyed by logging, burning for subsistence farms, and poaching. The 20 species of lemurs for which Madagascar is renowned are in danger of disappearing. Though there are game reserves, they’re not large (occupying only five percent of the island), nor are they contiguous, thus failing to provide corridors for the animals to travel through. Some of Madagascar’s endemic species have never even been recorded, and will likely be lost before they can be studied.
