Which action reduces the impact of human activities on ecosystems?

• A. Reducing pollution
• B. Expanding highways
• C. Clearing more forest
• D. Increasing mining

Answer: (A)

Reducing pollution helps ecosystems by keeping air, water, and soil cleaner, which supports the health of plants, animals, and the natural processes they rely on. When pollutants are lowered, fewer toxins enter habitats, water bodies, and food chains, helping species survive, reproduce, and maintain balanced ecosystems. This means fewer disruptions to things like population levels, migration patterns, and the availability of food and shelter that living things depend on. Expanding highways usually means more land is cleared and more traffic emissions enter the environment, which can fragment habitats and increase pollution. Clearing more forest removes homes for many species and disrupts ecosystems. Increasing mining disturbs the land, creates dust, and can contaminate water with minerals and chemicals. Each of these actions tends to harm ecosystems rather than protect them, making the choice to reduce pollution the best way to lessen human impact.
