Why organize natural world into biomes?
To understand why biomes are classified the way they are, you should know what characterizes a biome. Biomes (bioclimatic zones) are appropriate divisions by which to organize the natural world, because the organisms that live in each of them possess common constellations of adaptations to them, in particular to the climate of each of the zones and to the characteristic vegetation types that develop in them. All the elements of a biome exist in some meaningful relationship with each other, and change in one say the habitat, leads to a change in the biome. The original hunter/gatherer populations had relatively little effect on the environment, but with population increase, they have hunted out substantial proportion of large animals, and caused habitat destruction by small-scale slash-and-burn agriculture and large-scale land clearing for ranching and farming.
