A Natural region is a basic geographic unit. Usually it is a region which is distinguished by its common natural features of geography, geology and climate.

Thus most natural regions are homogeneous ecosystems. Human impact can be an important factor in the shaping and destiny of a particular natural region.

“The Heavens. Once an object of superstition, awe and fear. Now a vast region for growing knowledge. The distance of Venus, the atmosphere of Mars, the size of Jupiter, and the speed of Mercury. All this and more we know. But their greatest mystery the heavens have kept a secret. What sort of life, if any, inhabits these other planets? Human life, like ours? Or life extremely lower in the scale. Or dangerously higher.”
—Richard Blake, and William Cameron Menzies. Narrator, Invaders from Mars, at the opening of the movie (1953)
