How do humans impact 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 natural resources did the Mojave tribe use?

How is the Mojave Desert used?
In addition the Mojave desert is used by: tourists – visiting areas such as Death Valley. military, as they test out airplanes and train troops. hikers and rock climbers.

Global warming is increasing the incidence of drought, which dries up water holes. Higher temperatures may produce an increasing number of wildfires that alter desert landscapes by eliminating slow-growing trees and shrubs and replacing them with fast-growing grasses.
What are some environmental issues in the 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 did the Mojave tribe adapt to the environment?
They had an easier life because they had fresh water. The Mojave ate many different types of food like skunks, beavers, pumpkins, salmon, seeds, acorns, and melons. They cook fish then put them on sticks. The homes of the Mojave tribes protected them from the environment.

New study finds that the world’s largest desert grew by 10 percent since 1920, due in part to climate change. Summary: The Sahara Desert has expanded by about 10 percent since 1920, according to a new study.
How has the desert biome changed over time?
How is climate change affecting deserts?
Invasive species thrive with increased carbon dioxide, raising fire risk. Desert plants go wild during wet years when treated to excess carbon dioxide, researchers say. The finding backs up climate change models, which predict that rising levels of atmospheric CO2 will disrupt the ecology of sensitive desert ecosystems …
How did the Mojave tribe adapt to the natural environment?
Mojave people built two different types of houses. Close to the Colorado River, the Mojaves lived in thatched huts raised off the ground with stilts, to protect against summer flooding. Further from the river, Mojave people built sturdier earth lodges, which are made of a wooden frame packed with clay.
