Which statement best describes pollution?

• A. The removal of pollutants from the environment
• B. The process of filtering water
• C. The harming, contaminating and destruction of the natural environment
• D. The reinforcement of natural habitats

Answer: (C)

Pollution is the introduction of harmful substances or energy into the environment in a way that harms living things, contaminates air, water, or soil, and degrades ecosystems. The statement that best describes pollution focuses on this harm and contamination of the natural environment. The other options describe actions like removing pollutants, filtering water, or strengthening habitats—these are about cleaning up or protecting the environment, not about pollution itself. Think of pollution as those things that degrade environmental health, such as chemicals or trash entering air, water, or land and causing harm to animals, plants, and people.
