La ecología es la ciencia que se encarga de medir este impacto y tratar de minimizarlo.
Las acciones de las personas sobre el medio ambiente siempre provocarán efectos colaterales sobre éste. La preocupación por los impactos ambientales abarca varios tipos de acciones, como la contaminación de los mares con petróleo, los desechos de la energía radioactiva o desechos radioactivos/nucleares, la contaminación auditiva, la emisión de gases nocivos, o la pérdida de superficie de hábitats naturales, entre otros.
