Contrary to common belief, artificial islands have a lengthy historical background in many regions worldwide. This heritage dates back to the reclaimed islands in Ancient Egypt, the hundreds of Stilt crannogs found in Scottish and Irish lakes and waterways, and the ceremonial islands constructed during the Aztec Empire. By definition, an artificial island is an island that has been constructed by humans rather than formed through natural processes. Artificial islands can be built for many different reasons, and these reasons are only increasing as the world faces the looming issue of space scarcity.
In the past, these islands were intended for ceremonial or agricultural purposes, often verging on solutions for urban space. More recently, the islands have been built to mitigate overcrowding, reclaim land, provide new urban expansions, and meet infrastructure and industrial needs. Artificial islands also have certain strategic advantages and economic gains and can lead to geopolitical benefits. However, these types of projects come at a significant cost to our ecosystem, harming the environment in severe and vast ways.
