The diversity that exists in the world whether it is with respect to culture or people's skin-color or feature is what makes it a more exciting place to live in. Imagine your parent takes you to the zoo when you were a kid, and you find that all the animals are water-buffaloes instead of lions, tigers, gorillas, kangaroos, bears, rhesus monkeys, giraffes and so on. How boring of a zoo will it be if all the animals there are all of the same kind??? ;P -TM
