USA HISTORY

Detailed explanation-1: -Taken together: climate change, an over-reliance on agriculture, deforestation, difficult trading, failure to use local food resources, and resistance to learn from Inuit created a suite of troubles that eventually made their lives unsustainable in this remote northern place.

Detailed explanation-2: -From 1954, the United Nations no longer perceived Greenland to be a colony. Denmark preserved a significant territory at a time when most European colonies were declaring independence. Greenland was a Danish county until 1979 when it attained home rule.

Detailed explanation-3: -The classic explanation for their decline holds that settlers stubbornly clung to the European way of life, farming pasturelands for cows and sheep, even though it was not well suited to Greenland’s cold climate and rocky terrain.

Detailed explanation-4: -The lack of warmth during the growing season (low heat-sum) is a strongly limiting factor for tree growth in Greenland.
