What is a natural event that humans can influence according to the passage?

Natural resource extraction is a natural event that humans can influence because it involves the deliberate removal of resources from the environment, which can have significant ecological impacts. Humans actively shape the process through decisions about what and how much to extract, leading to changes in the landscape, biodiversity, and overall ecosystem health. This contrasts with events like earthquakes and tornadoes, which occur as a result of natural processes and are largely beyond human control. While humans can influence forest growth indirectly through activities like deforestation or reforestation, the act of extracting natural resources is a direct human intervention that alters natural systems.
