7 Places You've Got to See Before They're Gone

Thanks to climate change, some of the planet's greatest natural wonders are in danger, Time notes. Megan Gibson lists 10 that you shouldn't miss before they disappear:

1. Great Barrier Reef, Australia: It could be gone within a century as ocean temperatures climb and the reef suffers from pollution.
2. Venice, Italy: Not only is it sinking, it's dealing with worsening floods. Like the Great Barrier Reef, it could be uninhabitable within 100 years.
3. Dead Sea: Forty years have seen it shrink by a third. Its only source is the River Jordan—and nearby countries keep pulling water from the river.

4. Glacier National Park, Montana: It's got fewer than 25 glaciers these days; it once had 150. Get there before 2030, when they could all be gone, Gibson writes.
5. Maldives: It's the world's lowest-lying country—and it could be completely underwater within a century thanks to rising sea levels.
6. Seychelles: Another beautiful site that could disappear underwater within 50 to 100 years, the 115 islands in the Indian Ocean are facing beach erosion and coral destruction.
7. Alps: Their glacial ice melts at a rate of about 3% per year; the glaciers might not be there in 2050.
