The correct answer is D)

Decades ago, the U.S. government mandated that they and other Alaskan natives abandon a nomadic life based on hunting and fishing for sedentism.

Sedentism is the act of staying still in one place for an extended period of time.

Although for a different cause, such as ensuring the safety of people and property, other governments in various parts of the world also support the initiative.

What are climate change?

  • Long-term changes in temperature and weather patterns are referred to as climate change.
  • These changes might be caused by natural processes, such as oscillations in the solar cycle.
  • But since the 1800s, human activities—primarily the combustion of fossil fuels like coal, oil, and gas—have been the primary cause of climate change.
  • Fossil fuel combustion produces greenhouse gas emissions that serve as a blanket over the planet, trapping heat from the sun and increasing temperatures.
