How did the changing environment affect the lives of the early people
Answers
Answer:
Humans have been present on this Earth for nearly 3.5 million years. For 2million years, their way of life was based around hunting and gathering food until ten to twelve thousand years ago when agriculture evolved. Early humans depend upon their knowledge of crops and seasons in order for survival. as brain size increased and humans adapted to different environments, advances were made in human technology. Humans began to work with and occasionally against their environment to create a stable way to acquire food as well as a more stable lifestyle. On the other hand, the environment, the climate in particular, definitely dictated the movement and survival methods of early humans.
The seasonal changes, climate, and other atmospheric conditions created many challenges for early humans. Modern examples that demonstrate what life might have been like thousands of years ago show that seasons determine where humans can survive. For example The Netsilik Inuit living in Canada use their environmental surroundings for all the necessities of life. Their houses are made from snow and ice while their clothing, kayaks, sledges, and tents are made from animal skins. Their tools and weapons are made from bones and in the winter are used for seal hunting. In the summer the Inuit hunt caribou and fish for survival While hunting did cause a strain on some ecosystems, as Clive Ponting states in his book A Green History of the World: the Enviornment and the Collapse of Great Civilizations, “all gathering and hunting groups seem to have tried to control their numbers so as not to overtax the resources of their ecosystem
Even though early humans attempted to not be burdens of their ecosystem, Ponting does point out that the most dramatic impact that gathering and hunting groups had on their environment though was through hunting animals ” Most animals were defenseless against this new predation and overhunting was widespread problem especially since many groups of hunters tended to concentrate on one specific species. In some areas with a lack of plant variety, early humans began to kill large herds of bison and other large animals in very crude and wasteful ways such as luring them off cliffs or into canyons. “The changing environment put the greatest strain on these large animals, but hunting by humans would have had a devastating impact on a population already in decline and my have tipped the balance between extinction and survival
The changing climate played a crucial role in where humans actually resided. For example, it was only twelve thousand years ago when the last, long glacial period ended that humans attempted to live in Europe and were able to adapt to the harsh ecosystem. At that time Scandinavia, North Germany, Poland, the north-west Soviet Union, and the majority of Britain were covered in ice. Due to the low levels of plant life and vegetation, humans depended on large animal herds for existence as well as new tools and technology. The permanent settlement of Europe was a turning point for human existence because for the first time they were able to live and thrive in extremely severe climatic conditions (Ponting). The settlement of the Americas was also relatively late because the humans had to cross the difficult Siberian climate as well as the Bering Strait. On the contrary, early humans began to settle in the Australia fifty thousand years ago where food was readily available and the climate was very stable
