Ecology, the study of the relationships between organisms and their environment, appears in fiction in novels such as Frank Herbert's 1965 Dune, Kim Stanley Robinson's 1992 Red Mars, and Margaret Atwood's 2013 MaddAddam.[41][42] Dune brought ecology centre stage, with a whole planet struggling with its environment. Its lifeforms included giant sandworms for whom water is fatal and mouse-like animals able to survive in the planet's desert conditions.[43] The book was influential on the environmental movement of the time.[44]
