An Artificial Island is a man-made landmass created for various purposes, such as residential, commercial, or recreational use. These islands are often constructed using materials like sand, rock, and concrete, and can be built in oceans, seas, or lakes. They are designed to expand usable land area, support infrastructure, or protect coastal regions from erosion. One notable example of an artificial island is the Palm Jumeirah in Dubai, which is shaped like a palm tree and features luxury homes, hotels, and entertainment venues. Artificial islands can also serve ecological functions, such as creating habitats for wildlife or enhancing marine environments.
