For many years China has been actively engaged in the creation of artificial islands in the South China Sea, so it is not surprising that it was in this country that the world's largest ship designed for washing sea sand was created - Tian Kun Hao ("Creator of Magic Islands").
It is an enlarged version of the current vessels of this class. Its capacity is 6000 cubic meters. m. of sand per hour, which is commensurate with the capacity of three standard pools.
Artificial islands are created by washing huge masses of sand from the bottom of the sea. In this way, in particular, sites for military bases and airfields are being created.
In the world, artificial islands are most actively created by China and the United Arab Emirates. The Palm Jumeirah archipelago off the coast of Dubai is well known. The United States, some European states and Australia, where 50% of the coastline are supplemented by man-made structures, are not lagging behind them.
Despite the undoubted attractiveness of creating an "additional" land, skeptics express not unwarranted fears about its stability. So the aforementioned Palm Jumeirah archipelago has decreased compared to 2011 when it was built. Environmentalists also make their claims, pointing out the possible harm to the local ecosystem, since, in their opinion, artificial islands are a new form of urban development.
And yet, humanity is unlikely to give up artificial land. Thanks to her, in the near future it will be possible to increase the area of agricultural land and housing construction, which is very important in connection with the growth of the population. However, uncontrolled construction can cause serious harm to the environment.
Floating and even underwater cities can become an alternative to artificial islands.
