An impressive achievement of human engineering.

The artificial islands, “ornaments” in the middle of the sea that are not a creation of nature but human intervention in the natural landscape are now considered milestone cosmopolitan destinations such as Dubai, where the iconic Palm Jumeirah, or Hong Kong International Airport is located.

In any case, the way they are built on the water is surprised.

A video shared on Instagram shows the preparation process with internet users expressing their concern about the “fascinating but sad” process.

There are many different methods for creating artificial islands – the first of which is called recovery.

It is the composition of land in a water body through the deposition of soil, sand or other building materials at the bottom of the sea.

It is often collected from the bottom of the ocean and transferred to the desired location, where it is shaped and compressed to create land above water.

Sometimes the coasts of the island are “shielded” with stone or concrete to protect against water and waves.

Once stabilized, the island can grow with buildings, roads or resorts.

Recovered artificial islands take a long time to build and can be very expensive if they are built in deep or exposed waters.

As a result, their use is usually limited to 10-20 meters water depths and for conditions where the island is largely protected and based on reasonable solid foundations.

“That made me feel uncomfortable for some reason,” Enna Snow wrote.

Another person said: “Fascinating but sad. We play God and virtually destroy ourselves. Let’s not intervene »

Someone warned of the environmental impact, adding that it is crazy how much damage it should do to the bottom of the sea.

Another commented on the video as alarming.

It is worth noting that Dubai’s famous Palm Jumeirah was built through a huge land restoration project.

It concerned the outcome of 120 million cubic meters of sand from the bottom of the sea and blasted 7 million tonnes of rock from the nearby Hajar Mountains.

Then a crescent -shaped breakwater was built to protect the island from the waves and currents of the Persian Gulf.

The whole project took six years to build and cost $ 12 billion.
