Give an example of how a group of early Americans adapted to their environment, and one example of how a group changed their environment to fit their needs but shorter

Adaptation to environment: The Native American tribes of the Great Plains learned how to utilize the vast grasslands for hunting and gathering. They developed techniques like controlled burning to promote the growth of prairie grasses, which attracted herds of buffalo for hunting.

Changing environment: The early American settlers in New England cleared large areas of forests to create farmland for agriculture. They also built irrigation systems and waterways to divert and control water flow for crops, altering the natural landscape to meet their agricultural needs.
