What might be a fast change to the environment?

A fast change to the environment could occur through a natural disaster, such as a volcanic eruption or an earthquake, which can rapidly alter landscapes, ecosystems, and atmospheric conditions. Human activities, such as deforestation or industrial pollution, can also lead to swift environmental changes, impacting biodiversity and air or water quality. Additionally, sudden climate events, like hurricanes or floods, can drastically reshape habitats and displacement of species. These changes often have immediate and lasting effects on ecosystems and human communities.
