Environmental impact refers to the effects of human activities on the natural world. These effects can be seen in air, water, soil, and living things. Environmental impact is studied using data.

Activities such as building cities, producing goods, and using energy can change land, release gases, or create waste. Scientists measure factors like emissions, land use, and pollution levels. These impacts can be observed in different regions and ecosystems.

Environmental impact is studied in environmental science. It is tracked using global and local data systems.
