Question

which proposal best demonstrates a refined solution for reducing the negative impact of human activities on biodiversity in a farming community?
○ expanding farmland by clearing nearby forests to increase crop production.
○ using chemical pesticides more frequently to eliminate all insect species near crops.
○ creating buffer zones of native plants around fields to reduce runoff and provide habitat for wildlife.
○ draining wetlands near farms to prevent flooding during rainy seasons.

Explanation:

• Expanding farmland by clearing forests (first option) destroys habitats, reducing biodiversity.
• Using more pesticides (second option) harms non - target species, reducing biodiversity.
• Draining wetlands (fourth option) destroys wetland habitats.
• Creating buffer zones (third option) reduces runoff (which can carry pollutants harmful to ecosystems) and provides habitat for wildlife, thus helping to maintain or increase biodiversity in the farming community.

Answer:

Creating buffer zones of native plants around fields to reduce runoff and provide habitat for wildlife.
