TermDefinition
human activities Things people do that affect the environment, like farming, building cities, and using natural resources.
urbanization The growth of cities as more people move into them, often changing the land and environment.

invasive species Plants or animals that are brought to a new place where they don’t belong and can harm the local environment.
solutions Ideas or actions that help fix environmental problems.
simulations Models or computer programs that show what might happen in real life, used to study ecosystems or test solutions.
