Final answer:
Since the dawn of time, humans have actively been changing the environment to suit their needs, which has had significant ecological effects, including habitat destruction and contributing to global environmental issues.
Step-by-step explanation:
Since the beginning of human history, people have been changing the environment to fit their needs. This has involved various actions such as agriculture, where the clearing of natural landscapes like forests and wetlands enabled the establishment of farming areas.
The technology-driven modifications of human beings have reshaped ecosystems, as in the case of dam construction that alters water courses, transforming regional ecologies significantly.
Human activities have also led to widespread habitat destruction, placing numerous species at risk of extinction and causing large-scale environmental issues such as global climate change and ozone layer depletion.
