Environment and The Spice
A desert planet with no natural precipitation, in Dune it is established that Arrakis had been "His Imperial Majesty's Desert Botanical Testing Station" before the discovery of melange, for which it is the only natural source in the universe. Melange (or, "the spice") is the most essential and valuable commodity in the universe, as it extends life and makes safe interstellar travel possible (among other uses). The planet has no surface water bodies, but open canals called qanats are used "for carrying irrigation water under controlled conditions" through the desert. The Fremen collect water in underground reservoirs to fulfill their dream of someday terraforming the planet, and pay the Spacing Guild exorbitant fees in melange to keep the skies over Arrakis free of any satellites which might observe their efforts. As indicated by its large salt flats, Arrakis once had lakes and oceans; Lady Jessica also notes in Dune that wells drilled in the sinks and basins initially produce a "trickle" of water which soon stops, as if "something plugs it." Paul Atreides recalls that the few plants and animals on the planet include "saguaro, burro bush, date palm, sand verbena, evening primrose, barrel cactus, incense bush, smoke tree, creosote bush ... kit fox, desert hawk, kangaroo mouse ... many to be found now nowhere else in the universe except here on Arrakis." The most notable life forms on the planet are the giant sandworms and their immature forms of sandtrout and sandplankton. Sandtrout encyst any water deposits; predator fish are placed in the qanats and other water storage areas to protect them from the sandtrout. In Children of Dune (1976), Leto Atreides II explains to his twin sister Ghanima:
The sandtrout ... was introduced here from some other place. This was a wet planet then. They proliferated beyond the capability of existing ecosystems to deal with them. Sandtrout encysted the available free water, made this a desert planet ... and they did it to survive. In a planet sufficiently dry, they could move to their sandworm phase.

Famous quotes containing the words environment and, environment and/or spice:
“People between twenty and forty are not sympathetic. The child has the capacity to do but it can’t know. It only knows when it is no longer able to do—after forty. Between twenty and forty the will of the child to do gets stronger, more dangerous, but it has not begun to learn to know yet. Since his capacity to do is forced into channels of evil through environment and pressures, man is strong before he is moral. The world’s anguish is caused by people between twenty and forty.”
—William Faulkner (1897–1962)
“Today the young actors regard their environment with rage and disgust. They regard their Master not as disciples regard their Master, but as slaves regard their Master.”
—Judith Malina (b. 1926)
“Variety’s the very spice of life
That gives it all its flavour.”
—William Cowper (1731–1800)
