The world's most crowded islands

From an island microslum in Colombia to a haute enclave in central Paris, the ten most crowded islands in the world bear scant similarities in class or culture. In fact, every entry in the top ten comes from a different country. But being islands, each shares the common thread of scarcity - whether it be land, resources, or housing. In general, these islands are prophetical microcosms for an overcrowded earth - finite spaces where self sufficiency governs and demand pierces supply.

With the world's population racing higher and higher, and the "megacities club" accepting new members yearly, some day the earth could bear the traits of one of these densely packed islands.
