Humans have indirectly impacted the Sahara with their increasing growing ecological footprint . The temperatures of the early are rapidly increasing. There is an increase in infrared radiation escaping from the atmosphere into space. An indirect measure of how much heat is being trapped.
How is the Sahara Desert impacted by humans?
Increasing evaporation and dust storms are pushing deserts out into communities at their edges. This desertification is exacerbated by human exploitation of ecosystems that border deserts, causing land degradation, soil erosion and sterility, and a loss of biodiversity.
What are threats to the Sahara Desert?
Other major threats to deserts include overgrazing, woody-vegetation clearance, agricultural expansion, water diversion and extraction, soil and water pollution , land con- version due to industrial activities and associated threats from armed conflicts [19,21].
How do humans destroy the desert?
Growing Deserts
Human activities such as firewood gathering and the grazing of animals are also converting semiarid regions into deserts, a process known as desertification. Population growth and greater demand for land are serious obstacles in the effort to combat this problem.

What are the disadvantages of living in the desert?
Lack of water , the most evident disadvantage to deserts in general, results from the combined effects of insufficient rainfall and rapid water evaporation by nearby land masses. The rate of rainfall rarely exceeds the rate of evaporation, and it is not uncommon for rain to vaporize even before hitting the ground.
Can you survive in the Sahara desert?
Extremely hot and dry, deserts are still home to several life forms . And, despite desertification threatening fertile land, dust and sand from the Sahara can help sustain life and supply nutrients to the faraway Amazon.
