Years go by, rising temperatures from human activities has  sped up climate change in desert regions.  Defense mechanisms have weakened in all continent significantly.  Unique species are endangered and water scarcity is becoming a serious problem in large cities desert areas.  The Great Basin in California dreamin North America  has exhausted its capacity to provide water to several cities in the west coast.  Desert  and semi- arid land support Carbon 4 plants which are heat resistant, sustained in extreme hot temperatures, absorb carbon dioxide during the day.  

Unique species in desert biome 

Desert is a harsh environment and requires resiliency in order to survive in the scorching heat.  Human activities is one of the main culprit that has reduced amount of precipitation  in many deserts around the world.   But nature fights back in the desert, there some species that are untouchable, except certain species are able to thrive in hard times.

Penstemon Flower is a unique plant that survived the Dust Bowl in the 1930’s Midwest climate crisis.

Desert land support the economy worldwide,  there are rich minerals such as Copper, diamond, coal, Silver, titanium, uranium.
