Many of the famous tourist attractions around the world could disappear within the next 50 years.
Some are so at risk that they may be gone within just a couple of decades.
Whilst climate change and rising sea levels is a huge problem for many, an increase in tourism is also causing more damage to some of the ancient sites.
The World Tourism Organisation (UNWTO) has explained how many could soon disappear.
They stated: “Rise of sea levels will eventually submerge small islands and coastal regions. Regions depending on tourism are under threat.
“Melting of snow and glaciers – one of the causes behind rising sea levels, and also affecting mountains and ski resorts, [is] resulting in the shift of destination demands, depending on the most attractive climate conditions.”
Those looking to tick off their bucket list may be the last in their generation to experience them.
The ‘floating city’ is well known for how often it floods, with St Marks Square often under water..
With the Mediterranean Sea rising by up to five feet in the next 80 years, this will badly affect Italy’s coastline.
Therefore this beautiful tourist town could be completely submerged by 2100.
Columbia Glacier, Alaska
Many of the glaciers in the Northern hemisphere are beginning to melt and drop into the ocean as the world heats up.
The famous Columbia Glacier in Alaska is one of the fastest moving in the world as it quickly disappears.
It could be gone and instead become a large fjord in just 50 years, according to scientists.
Machu Picchu, Peru
The Inca trail, chosen by many gap year students, could also disappear although for different reasons.
With the number of people visiting, the ancient city is being destroyed and eroded as many trample over the delicate buildings.
The tropical islands are a favourite among honeymooners and couples for its idyllic resorts.
However, with rising sea levels expected to rise 97cm by 2100, and the islands just 1.5 metres above sea, it could mean they are submerged sooner than many may realise as the Indian Ocean islands are the first to be affected.
Professor Chris Perry from the University of Exeter said: “Many of the heavily populated islands in the Maldives have limited capacity to respond naturally to sea level rise and this will necessitate additional spending on shoreline maintenance.”
Mount Kilimanjaro, Tanzania
The tallest mountain is under threat, as the ice cap it is so famed for that rests on the top of the mountain is heating at a high rate.
Scientists predict it could be completely gone in just 16 years.
The Dead Sea, Israel
Many flock to try out the Dead Sea for themselves, which causes travellers to unnaturally float in the salty lake full of minerals.
However, located at one of the lowest points on Earth, it is starting to evaporate under the heat of the sun.
As it drops by over a metre year and countries surrounding it draws its water it’s source of the River Jordan it could be gone within 50 years.
Taj Mahal, India
The biggest tourist attraction in India could be gone sooner than many may realise due to various reasons.
The tourism to the area has caused damage to the tombs and the floors from people walking along it.
The water level decreasing from the nearby Yamuna River has also affected the wooden foundation it is built on, meaning it could soon collapse.
