How do humans affect the desert ecosystem?
Human exploitation of fragile ecosystems can lead to the droughts and arid conditions characteristic of desertification. Effects include land degradation, soil erosion and sterility, and a loss of biodiversity, with huge economic costs for nations where deserts are growing.

How does a natural ecosystem work?
The natural ecosystem is a community of living and non-living organisms, where each component interacts together as a unit through biological, physical and chemical processes. The distinctiveness of natural ecosystems is that they are purely natural and their formations are not in any way influenced by human activity.
What are the importance of desert to the ecosystem?
The dry condition of deserts helps promote the formation and concentration of important minerals. Gypsum, borates, nitrates, potassium and other salts build up in deserts when water carrying these minerals evaporates. Minimal vegetation has also made it easier to extract important minerals from desert regions.

How can we save the desert ecosystem?
Major desert restoration techniques include: planting and seeding, managing water, manipulating soil properties, and providing cover. Controlling non-native species often also is part of restoration and subsequent maintenance management in the restored ecosystem (D’Antonio & Meyerson 2002).
Is Desert a ecosystem?
