How do decisions made by humans alter and impact the natural terrestrial ecosystem?

Human decisions, such as deforestation, urbanization, and agricultural practices, significantly alter terrestrial ecosystems by disrupting habitats and reducing biodiversity. These actions can lead to soil degradation, increased greenhouse gas emissions, and altered water cycles. Additionally, pollution from industrial and agricultural runoff can harm plant and animal species, further destabilizing ecosystems. Ultimately, these changes can diminish ecosystem services that are vital for human survival, such as clean air, water, and food resources.
