The atoll is a coral island located mainly in the warm tropical or subtropical zones of the planet. Because of its picturesque nature, it is the nature of the atolls that is associated with heavenly relaxation for the majority of the planet's population. In addition, such natural formations have their own particularity – they almost always have a round shape. What caused this phenomenon and how can it be explained?
Why are atolls ring shaped?
According to the great scientist Charles Darwin, the atoll is nothing more than what remains after the flooding of the island. According to his theory, corals settle near the rocky shores of the country, which gradually penetrate into the depths of the sea. When a part of the coral goes underwater, they die and gradually turn to limestone. The formed calcareous platform begins to lead a new life and becomes the habitat of new coral generations, which in the course of time penetrate ever higher towards the light. Until the island is completely submerged, the corals form a ring with an inner lagoon.

Modern scientists believe that atolls are mainly formed on volcanic islands. The most famous seaside resort in the world – the Maldives – is composed of atolls, coral islands and coral reefs. All barely extend beyond the surface of the Indian Ocean: it is known that the highest point of the Maldives is the point of Addu. For a better understanding, the slide is only 2.4 meters high.
Of the 1,200 Maldivian islands, only 200 are currently inhabited, the remainder being used in tourism and agriculture. Nevertheless, all Maldivian islands are a unique formation whose analogues simply do not exist when viewed from a biodiversity point of view.
Despite its natural imagery, the Maldivian atoll could disappear in the near future. Due to global warming, the level of the oceans is gradually rising, flooding the banks of the Paradise Islands. The date of the complete disappearance of the islands varies: Someone believes that the Maldives can disappear after about 100 years, and someone believes that the Maldives can disappear after 30 years. To survive the apocalypse, Maldivian entrepreneurs are already developing the New Maldives.
Do you believe that it is possible to save the atolls from the effects of global warming? Let's try to discuss this problem in our telegram chat.
In particular, the construction of the world's first underwater restaurant Ilthaa Undersea is already underway. It is not yet known if all residents of the Maldives will go underwater. At the same time, we will find a solution to this problem in the coming decades.
