Certains monuments célèbres pourraient ne pas être éternels, alors profitez-en tant que vous le pouvez ! La Statue de la Liberté est menacée par la montée des eaux, et le Sphinx à Gizeh s'érode lentement à cause de la pollution et du vent. La Tour Eiffel, bien qu'elle soit en fer, est susceptible de rouiller et de s'usure avec le temps. Le Taj Mahal lutte contre la pollution et une fondation qui s'affaiblit. Ces sites emblématiques sont en danger, alors les visiter plus tôt que tard est une bonne idée ! Animation créée par Sympa.

FunTranscript
00:00There are things that go together, like popcorn and movies,
00:04mornings and coffee, New York and the Statue of Liberty.
00:08I bet you can't imagine Paris without its Eiffel Tower,
00:12or India without its Taj Mahal of a stained white.
00:16But you may have to adapt to a new image of the world,
00:20because these emblematic monuments, and many others,
00:23will probably disappear in the next decades.
00:27Before jumping in a taxi to the airport, here is a list.
00:33The symbol of Paris has existed since 1899.
00:37The tower was not supposed to last centuries.
00:40It was planned to be dismantled 20 years later.
00:43For a lady of her age, this celebrity is doing pretty well.
00:48But as it is made of iron, its most dangerous enemy is corrosion.
00:53If we put the tower in a protective case, it would no longer be so beautiful.
00:58It is there, in the open air, exposed to water and air,
01:02and it slowly oxidizes.
01:05The authorities know this, but they are happy to repaint it every seven years.
01:11It was renovated for 65 million dollars before the Paris Olympics in 2024,
01:17but critics say it is not enough to solve the problem of rust.
01:21Another thing that bothers the tower is the wind, which makes it slightly vibrate.
01:26And then there is the sun, which heats the east, south and west faces of the tower one by one,
01:32and makes them inflate.
01:34At nightfall, they resume their initial state.
01:38Thus, the top of the tower follows an almost circular curve every 24 hours.
01:43Because of these movements, the metal of the structure weakens,
01:47and this could become a long-term problem.
01:50It's like folding an iron wire several times.
01:53At one point, it breaks.
01:57It took about 20 years and about 20,000 workers to complete one of the most beautiful constructions in the world.
02:04The Taj Mahal.
02:06It was supposed to have a twin brother in black, but the idea was quickly abandoned.
02:10Unfortunately, this is not the worst news about this marble beauty.
02:15Its demolition is the subject of debate.
02:18Indeed, one of the seven new wonders of the world could disappear because of the excess of vehicles,
02:24coal combustion, dust storms and forest fires that make the ambient air at least harmful.
02:30The white marble, formerly sparkling, has gradually lost its brightness
02:35and has changed color to take on various shades of yellow, brown and green.
02:40There is another problem.
02:42Thousands of small insects who appreciate the beauty of the Taj Mahal so much
02:46that they have chosen to make it their home.
02:49They come directly from the Yamuna River, which is not the cleanest in the world.
02:54And what they produce on a daily basis, namely their excrement, corrodes and stains the marble.
03:00The second problem is that the Supreme Court of India has threatened to close the site
03:05unless the authorities take measures to preserve this monument.
03:10I hope they will find a solution.
03:12Otherwise, what will 8 million tourists who come here every year to spend their holidays do?
03:19If you have ever been to Egypt, you must have at least one picture of you pretending to hold the legendary sphinx.
03:27No? Just me?
03:29Anyway, Gizeh's sphinx had already lost its nose.
03:33And we still don't know how or why it happened.
03:37And after centuries of erosion of its limestone,
03:40the famous giant could well disappear from our living.
03:45Because of its environment, the western part of the sphinx is subjected to a large natural flood of rainwater.
03:52Rainfalls are rare in Egypt, but it still rains from time to time.
03:57Water is not the only problem with the sphinx.
04:00As it is in the desert, the violent winds are also devastating.
04:05They cause the sandblasting of the monument.
04:07It is as if an invisible hand was gradually damaging its delicate and grainy surface.
04:13There is also groundwater.
04:15It infiltrates the porous rocks with the salt present in the soil.
04:19Humidity is not good for these massive constructions.
04:22The sphinx and the pyramids have survived for centuries.
04:26But if the elements clash with each other, these colossi will have no chance of winning.
04:33The Statue of Liberty has already undergone a major transformation since its first unveiling in 1886.
04:40Before, it was a bright brown color, like a penny.
04:4420 years later, it has become green.
04:47Lady Liberty is covered with hundreds of thin leaves of copper.
04:51When the copper is exposed to the air, it naturally forms a protective layer called gray glass.
04:58This is why statues and other objects made of copper, brass and bronze can last so long.
05:05When the statue became green for the first time, the authorities decided to repaint it.
05:11But the public did not like the idea.
05:14Experts confirmed that it should not be done, because removing the protective layer would destroy the statue.
05:20Lady Liberty always receives a good amount of rain, so that the chemical reactions continue.
05:26The polluted air around it only accelerates its reactions.
05:30The city of New York does what it can to protect its symbol.
05:34We will see if it will be enough to save it.
05:37When Machu Picchu in Peru was discovered for the first time in 1911, its explorer thought he had found the lost city of the Incas.
05:45Several decades later, it turned out that it was not the same city, but that does not take away its charm, does it?
05:52The stones that make up these buildings are carved with such precision and are packed so tightly that it is impossible to insert a credit card.
06:01This has allowed the city to avoid serious earthquakes, which are frequent in the region.
06:06The buildings dance under the effect of earthquakes and are put back in place.
06:10But there is another problem.
06:12The people.
06:13About 4,000 tourists come here every day and destroy the ruins on their way.
06:18Local authorities are trying to put an end to this by suspending visits to certain temples and structures.
06:24When the site was completely closed for a month, many inhabitants who depend on tourism got angry and rose up against this decision.
06:33They must therefore find a solution to save Machu Picchu without closing it.
06:38Hundreds of thousands of tourists are trying to get it back on track to take nice pictures.
06:44But can we really save the tower leaning from Pisa from a fatal fall?
06:48It began to tilt south shortly after the beginning of its construction, in the 12th century, due to the fragility of the ground under its foundations.
06:56This ground could not withstand the weight of the heavy white marble and began to crumble.
07:01These builders decided to show creativity and build each of the successive floors at a different angle to correct the inclination.
07:10But that was not enough.
07:11When three of the eight floors were finished, the inclination worsened so much that they had to interrupt the work to solve the problem.
07:19When the tower was finally ready, it tilted by 1.6 degrees.
07:24Almost three centuries later, an architect who worked on the tower wanted to show the world the magnificent sculptures at the base of the building.
07:33He shouldn't have done it, because it made the construction lean like never before.
07:38In the middle of the 20th century, while the tower was already leaning by 5.5 degrees,
07:43the Italian authorities decided that it was no longer funny and invited experts to save it from a definitive fall.
07:51They had the idea of extracting the earth from the foundations north of the tower to straighten it.
07:57This method worked and allowed to pull the tower in the opposite direction of the inclination.
08:03The team had to repeat the process for several years, in 41 different places.
08:10I will probably have given up after the third place.
08:13I have no patience.
08:15In May 2008, the tower finally straightened up and was finally immobilized.
08:21Experts think it will hold for a while, but if a powerful earthquake occurs, its future may be bleak.
