By and large, the world is kept in balance by its diversity. The strength of this diversity is that not all varieties of a crop get destroyed, and not all of a population succumbs to a particular illness.
Values of diversity, whether biological, cultural or linguistic, are intrinsic to life itself and celebrated by the myriad cultures and societies that have co-evolved with the natural and metaphysical worlds that surround them. Human beings are an integral part of biodiversity.
