The ecology of Dune is intricately tied to its harsh desert environment, characterized by extreme temperatures and limited water. The planet is home to unique flora and fauna, including the giant sandworms, which play a crucial role in the ecosystem. These creatures are essential for the production of melange, a valuable spice that enhances mental abilities and extends life. The survival of life on Dune depends on complex relationships between species and their environment. The native Fremen people have adapted to the desert conditions, utilizing water conservation techniques and understanding the ecological balance. Their practices highlight the importance of sustainability in such a fragile ecosystem.
