Detailed explanation-1: -Native American tribes hunted buffalo. The tribes also set fires to burn prairies and prevent the growth of trees. This left the prairie as an open grassland ideal for hunting bison.

Detailed explanation-2: -Often these hunter-gatherers interfered with wild vegetation for the purpose of promoting the growth of a particular plant by sowing its seeds. They also uprooted and destroyed flora deemed undesirable. These types of environmental modification were frequently aided by the use of fire.

Detailed explanation-3: -Hunter-gatherer societies cleared grassland by setting fires and contributed to the extinction of some large mammals. The agricultural revolution caused human population growth, habitat loss, soil erosion, and the domestication of plants and animals.

Detailed explanation-4: -Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
