Creuser des trous dans le sable peut sembler être un amusement inoffensif, mais cela peut en réalité être très dangereux si le trou est profond. Si le sable s'effondre sur quelqu'un, il est extrêmement difficile de s'échapper parce que le sable est lourd et dense. Des recherches montrent même que plus de personnes meurent en étant piégées et asphyxiées dans le sable que par des attaques de requins ! Contrairement à la neige, qui est plus légère et vous donne une chance de créer une poche d'air si vous êtes piégé, le sable ne permet pas cela. Une fois qu'il tombe sur vous, il est presque impossible de bouger. Alors la prochaine fois que vous êtes à la plage, faites attention à ces trous profonds ! Animation créée par Sympa.

FunTranscript
00:00When you think of the beach, the first scary thing that comes to mind is probably the sharks, isn't it?
00:07These poor boulders have the bad reputation of being the big raw fish of the ocean.
00:11But honestly, they cause a lot less fatalities than jellyfish, algae and even sand.
00:17Every year, tons of people go to the beach to enjoy the sun and relax near the waves.
00:23But digging holes in the sand can be very risky.
00:26In February 2024, a tragic incident occurred.
00:30A 7-year-old girl was trapped after the collapse of a hole about 1.5 meters deep that she had dug with her brother.
00:38Despite the efforts of the passers-by to rescue her, the rescue arrived too late.
00:43You may think that digging in the sand is harmless, but deep holes can be a deadly trap.
00:49Sand is defined by its size and not by its material.
00:53Beach sand is generally made up of quartz, but tropical regions can be covered with coral sand.
01:00The weight of the sand depends on what it is made of.
01:02Pure quartz is quite light, about 1,044 kg per cubic meter, but more mixed sand can be much heavier.
01:11When the sand is wet, it keeps its shape well.
01:15But once dry, it's a whole other story.
01:18If you dig a hole and the sand dries, it may collapse.
01:22The danger increases considerably if someone stands near the edge.
01:26The weight of the person makes the hole even more unstable.
01:30Once the sand starts to fall, it fills all the air pockets,
01:34which makes breathing difficult for trapped people inside.
01:39Saving a person in a sandslide is not an easy thing.
01:43The sand is heavy and never stops collapsing.
01:45Rescuers must act quickly.
01:48Ideally, they have 3 to 5 minutes before the trapped person suffocates.
01:53If you ever find yourself in such a situation,
01:56it is advisable to expose the mouth of the person so that they can breathe while someone else works to clear it.
02:04If you go to the beach, show discernment about the holes.
02:09The best rule is to never dig a hole deeper than the knees of the smallest person in your group.
02:15It is also advisable to fill the holes once you have finished playing.
02:19Someone could easily get stuck in a forgotten hole,
02:22and even a shallow hole can cause injuries.
02:25Between 1997 and 1207,
02:29holes in the sand cost the lives of 31 people in the United States.
02:33Yes, in just 10 years.
02:35Do you remember that I told you that sharks were responsible for fewer deaths?
02:40From 1997 to today,
02:42in 27 years,
02:4429 people have prematurely died in the United States because of sharks.
02:48Going to the beach and finding only a pile of algae?
02:51A real disappointment.
02:52But if some algae are quite acceptable,
02:55even to taste,
02:56others can pose serious health risks.
02:59Even if you only approach them.
03:01Algae proliferation, or red tide,
03:04occurs when the algae develop in an unbridled way.
03:08These efflorescences can release harmful toxins that are harmful to humans,
03:12fish, crustaceans, and even birds.
03:15One of the most famous algae efflorescences occurs almost every summer on the coast of the Gulf of Florida.
03:21Even those that are not toxic can disrupt the ecosystem.
03:24When the algae flutter and decompose,
03:27they consume all the oxygen in the water,
03:29leaving the fauna and flora literally out of breath.
03:33It is absolutely necessary to avoid consuming shellfish from areas affected by these toxic algae proliferations.
03:40In 1990,
03:42six fishermen almost met a tragic end
03:45after swallowing steam-cooked molds that they had collected near Cape Cod,
03:49in Massachusetts.
03:51Swimming in these waters does not always present a serious health risk,
03:55but it remains unadvised.
03:57Some people may suffer from skin irritation or eye diseases.
04:02Also be careful not to swim near dead fish,
04:05because harmful bacteria can proliferate.
04:08And if you start to feel weird after entering the water,
04:12it is preferable to go out and rinse yourself in fresh water immediately.
04:16You know, it is not always a specific factor that makes some beaches dangerous.
04:21Sometimes the beaches themselves are full of surprises.
04:24Take for example Etibay or Mission Beach in Australia.
04:28You will probably have to share the sand with the cassowary,
04:31the most intimidating birds on the planet.
04:34Imagine that you are about to relax and take a sun bath,
04:38and that you discover these giant birds,
04:40unable to fly, not far from your towel.
04:43They look like seagulls, but more frightening.
04:46They can weigh more than 72 kilos and can be a little aggressive.
04:50So be careful.
04:52If these birds do not scare you,
04:54the black sand beaches of Kilauea could be a good deal.
04:57They have a welcoming air,
04:59but these beaches are located right next to one of the most active volcanoes in the world,
05:03Mount Kilauea, which has been erupting since 1984,
05:06and pours its burning lava into the ocean.
05:09But these warm waters are nothing compared to some Hawaiian beaches.
05:14Swimming in Hanakapiai Beach, on the coast of Napali in Kauai,
05:18is a very bad idea.
05:20The beach is sadly famous for its powerful currents,
05:23which can drag you ashore in an instant.
05:26If you get caught in one of these currents,
05:28you will very quickly be taken 10 km from the nearest shore.
05:32Official records state at least 30 deaths,
05:35but a panel located on site has more than 80.
05:38The rip currents pull the water offshore
05:40and can quickly drag people and objects
05:43far from shallow waters located near the beaches.
05:47In general, they move at a speed between 1.6 and 3.2 km per hour,
05:53but they can reach up to 8 km per hour.
05:56The best professional swimmers are not so fast.
05:59These currents are particularly violent when the rip is important,
06:03but you should never underestimate a stream of water.
06:06You can also find rip currents at the mouth of rivers,
06:10in estuaries, and even near lakes.
06:13It can be difficult to spot them.
06:15If you notice a water zone agitated at the surface of the ocean,
06:19it may be a rip current.
06:21These currents are not specific to a particular place.
06:24They can be found all over the world.
06:26In Playa Zipolite, Mexico.
06:28In Fraser Island, Australia.
06:30The list is long.
06:32Another danger related to water is that of rip waves.
06:35These are violent waves that come directly to the beach,
06:39often on the sand.
06:41Imagine the force of a car crashing on your body.
06:44It's a bit like what you feel when you encounter a rip wave.
06:48These waves can cause serious injuries,
06:50especially to the neck and spine,
06:53even if they don't look that bad.
06:55Hawaii is known for its intense rip waves,
06:58especially in places like Keiki Beach,
07:01where surfers attack the wind,
07:03looking for strong sensations.
07:05If you go to a Hawaiian beach,
07:07keep an eye on the rip waves,
07:09and always watch out for lifeguards.
07:11People who like to swim, play, or dive in the ocean
07:14are often victims of jellyfish bites.
07:17Their long tentacles release venom
07:19by means of thousands of small, sharp darts.
07:22However, for us, humans,
07:24this venom is generally not very serious.
07:27Yes, it's very unpleasant,
07:29because the burn can be intense
07:31and our skin will turn a little red.
07:33But that's all.
07:34You won't even see the bitten area after a few days.
07:37Most jellyfish bites heal themselves
07:39in a few days or weeks,
07:41averaging a few home care,
07:43even if they can sometimes lead to
07:45much more serious symptoms.
07:47However, if you find yourself
07:49in the coastal waters of northern Australia
07:51and the Indo-Pacific region,
07:53and you are bitten by a jellyfish,
07:55you may be in big trouble, my friends.
07:57Indeed, it is in this region
07:59that jellyfish live.
08:01And they are not kidding.
08:03Some people rightly call them
08:05sea geckos.
08:07They are probably the most dangerous
08:09and most toxic jellyfish in the world.
08:11Their bite is incredibly atrocious,
08:13to the point that some victims
08:15had a heart attack
08:17before even being able to reach the shore.
08:19According to the rumor,
08:21these jellyfish have been responsible
08:23for the death of nearly 80 people
08:25in Australia since they were first identified.
08:27So, how to recognize them?
08:29Unlike ordinary jellyfish,
08:31jellyfish are pale blue and transparent.
08:33They owe their name to the fact
08:35that their bell-shaped body
08:37looks like a cube.
