Remember that bucket list you've been making ever since you were fourteen, of visiting every heritage wonder of the world? Well, about time you started checking things off of that list because some of those places are starting to disappear and/or deteriorate. Here's a list…
 

The Great Barrier Reef | Australia

The Great Barrier Reef | Australia

Due to the rising sea temperatures and coral bleaching—the phenomenon of corals losing their nutrients and colours and turning white, this UNESCO world heritage site faces a global threat.

 

The Taj Mahal | India

It's heartbreaking to think of a wonder of the world to be deteriorating—but it's happening. The pollution in the city and from the industries nearby is having a serious impact on the mausoleum.

 

The Dead Sea | Jordan

The Dead Sea | Jordan

Known for being one of the few water bodies where humans can actually float on water (due to its high salinity), the Dead Sea too faces a threat due to a decline in water levels and appearances of sinkholes for natural and man-made reasons alike.

 

Machu Picchu | Peru

Machu Picchu | Peru

You probably remember Diplo standing on top of it in the opening frame of the song ‘Mind’ (with Skrillex). It was captivating, but today, it's deteriorating due to natural factors such as soil erosion and deforestation, with a possible threat of landslides.

 

Mount Kilimanjaro | Tanzania

Mount Kilimanjaro | Tanzania

The snow caps on Africa’s highest mountain are melting away at a drastic pace due to change in climatic conditions and again, deforestation, such that scientists predict the glaciers might cease to exist altogether decades down the line.
