Five places worth seeing soon are Easter Island, Antarctica, the Great Barrier Reef, the Dead Sea and the Taj Mahal, because each faces pressure from climate, tourism or pollution. None of them is about to vanish tomorrow, and some of the news is better than it was a few years ago. This guide updates each place with the latest figures from October 2026.
| Place | The pressure | 2026 snapshot |
|---|---|---|
| Easter Island | Tourism growth on a remote island | Nearly 1,000 moai, UNESCO site since 1995 |
| Antarctica | Rising cruise numbers | 124,000 cruise visitors in 2025 |
| Great Barrier Reef | Warming seas, bleaching | Northern coral cover rebounded to 35.1% |
| Dead Sea | Receding water | Surface 439.78 m below sea level in 2025 |
| Taj Mahal | Air pollution, crowds | About five million visitors in 2022-23 |
Many of the world's sights change over time because of climate, development and the number of people who visit. Development is another danger for once-pristine, off-the-beaten-path spots and their cultures. Always travel respectfully and responsibly.
1. Easter Island
This Polynesian island in the southeastern Pacific is famous for its nearly 1,000 moai, monumental statues made by the Rapa Nui people. It is one of the most remote inhabited islands in the world, with the nearest town of more than 500 people about 2,600 km away. UNESCO named it a World Heritage Site in 1995.
The island has a small population, so growth in tourism has an outsized effect. Visit with a local guide, stay on the marked paths and do not touch the statues.
2. Antarctica
Cruise tourism to Antarctica reached about 124,000 visitors in 2025, mostly travelling to the Antarctic Peninsula from South America. Visitor numbers passed a 2014 forecast of 120,000 by 2060 already in the 2023-24 season, and researchers have raised concerns about the impact. Most tour operators are members of the IAATO, which sets safety and environmental guidelines.
You can book through operators such as Abercrombie & Kent. Choose an operator that follows IAATO rules.
3. The Great Barrier Reef
The world's largest coral reef system has over 2,900 individual reefs and 900 islands, stretching over 2,300 km off Queensland, Australia. It has been hit by repeated mass bleaching: Australian scientists count six mass bleaching events between 2016 and 2025.
There is better news in 2026. The Australian Institute of Marine Science reported on 11 August 2026 that hard coral cover in the Northern region rose to 35.1% from 30.0%, and in the Central region to 31.6% from 28.6%. The Southern region slipped to 26.4%. A late monsoon with more cloud cover and cooler water limited bleaching in summer 2025-26. The reef is recovering but still under pressure. Look, but do not touch the coral.
4. The Dead Sea
The Dead Sea is the lowest land-based elevation on Earth, and in 2025 its surface was 439.78 meters below sea level. It is receding quickly: its surface area is about 605 square kilometers, down from 1,050 in 1930. Estimates for the annual drop in level range from about 1 to 1.5 meters, with about 1.2 meters the most recent figure we found.
It is called Dead because its salt content, around 34%, leaves little living in the water. Float on it while you can, and respect local rules about the shoreline, where sinkholes have appeared.
5. The Taj Mahal
The Taj Mahal is a 17th-century mausoleum, a UNESCO World Heritage Site since 1983 and one of the best examples of Mughal architecture. It receives more than five million visitors a year, about five million in the financial year 2022-23. Pollution and acid rain have yellowed the marble, and the Supreme Court of India has ordered action to protect it.
A claim in our earlier version that the monument may close to the public is not supported, so we removed it. Visit early in the morning, when the crowds are thinner and the light is best.

FAQ
Which places should I see before they change?
Easter Island, Antarctica, the Great Barrier Reef, the Dead Sea and the Taj Mahal are on our list.
Is the Great Barrier Reef dying?
No. AIMS reported in August 2026 that coral cover rose in the Northern and Central regions, though the reef remains under pressure after six mass bleaching events between 2016 and 2025.
How fast is the Dead Sea shrinking?
Estimates range from about 1 to 1.5 meters a year in level, with about 1.2 meters the most recent figure we found.
How many people visit Antarctica?
About 124,000 cruise visitors went in 2025.
Is the Taj Mahal closing?
We found no evidence of a planned closure. It received around five million visitors in 2022-23.
How we put this list together
We checked each place against current published figures from heritage bodies, scientists and tourism associations in October 2026, and removed claims that were not supported.
