Old cells hang around as we age, doing damage to the body. The success of the vaccine rollout also depends crucially on the Surface albedo is high - heat acquired during the day is radiated at night. Desertification has been described as "the greatest environmental challenge of our time" and climate change is making it worse. It is valued as much for its vivid descriptions and beautiful writing as it is for its content.

There may also be an extreme variation between warm and cool seasons, including extreme winds and storms due to the mixing of cold and warm air. Salts have also proven a great resource for the Chilean economy although today its lithium resources have also taken prominence on the world stage as battery development increases for better power storage and production in the new generation of electric cars (28). Even after these lakes ceased to exist, humans survived for centuries in the desert using alternative methods: nomadic pastoralists herded goats, sheep, or camels to whatever pasturage could be found; sedentary agriculturalists, confined to oases, harnessed their limited water resources to grow crops such as date palms and barley; and specialists (for example, blacksmiths) traded wares with their agriculturalist and pastoralist neighbors. The phenomenon has created the driest environment in the North American continent and straddles the states of Nevada and California, while edging across the Utah and Arizona borders too. Sub-Saharan Africa will be the world's slowest growing region in 2021, and risks falling further behind as the global economy rebounds.

Also, from a timescale perspective, how quickly will this technology be available at scale? said Mathis Wackernagel, president of the Global Footprint Network, an Oakland, California-based sustainability think tank. The effect could magnify over time, he warns, as exotic species recover faster after a blaze, building up fuel quickly for the next fire. The reputation of deserts as cold and lifeless is unfounded and it has arguably led to desert biomes being ignored in research literature compared to others (20).

The viability of plant life near oases is threatened due to high populations of domestic animals that graze on insufficient amounts of vegetation. These bodies predate the mummification process and therefore, no embalming fluid or removal of organs that degrade quickly as seen in the later industrial process of the complex society.
