Answer:
Dendrochronologists study tree rings to learn about past climates. Trees in temperate areas form one growth ring per year. Scientists can look at the rings and identify climate conditions during each year of the tree’s life. Scientists found long droughts in both the twelfth and thirteenth centuries. This is the same period when the Anasazi were leaving Chaco Canyon. Under normal conditions it was hard to support their villages in the harsh environment of northern New Mexico. When years of drought occurred, the densely populated Anasazi pueblos could no longer raise enough food. Other forces could have pushed the Anasazi away from Chaco as well.

Explanation:
Human survival on Mars would require living in artificial Mars habitats with complex life-support systems. One key aspect of this would be water processing systems. Being made mainly of water, a human being would die in a matter of days without it. The atmosphere on Mars is mostly made of carbon dioxide. It is also 100 times thinner than Earth's atmosphere, so even if it did have a similar composition to the air here, humans would be unable to breathe it to survive. In these conditions humans die within minutes unless a pressure suit provides life support. If Mars' atmospheric pressure could rise above 19 kPa (2.8 psi), then a pressure suit would not be required. Mars' atmosphere is dominated by carbon dioxide (CO₂) at a concentration of 96%. Oxygen is only 0.13%, compared with 21% in Earth's atmosphere. Moxie is able to strip oxygen atoms from CO₂ molecules, which are made up of one carbon atom and two oxygen atoms.
