Introduction to the Palm Artificial Islands in Dubai: There are three artificial islands in total, the smallest of which is Palm Jumeirah, and the other two are Palm Island Deira and Palm Jebel Ali. The plan costs US$14 billion. Looking down from a high altitude on Dubai, United Arab Emirates, two huge palm trees can be vaguely seen floating on the blue sea. However, these two are composed of a patchwork of islands of various sizes.
