Human beings are an amazing species. Given enough time, they will multiply, relocate and establish even on the most remote corners of the world. The following islands, I’m sure, were once uninhabited full of lush green forest, beautiful beaches and perhaps an animal or two. Today, entire cities stands on them. But unlike communities on mainland, land and resources on an island are scarce. With no space to grow geographically these islands are crushingly dense with people and housing.
