What is one example of a positive impact of humans on the environment in Fairfax, Virginia?

• A. We have industrial zones
• B. We have parks, which are home to many animals
• C. We drain wetlands
• D. We pollute streams

Answer: (B)

Providing and preserving green spaces in cities shows a positive impact because parks create and protect habitat for wildlife, support biodiversity, and offer valuable ecosystem services. In Fairfax, parks give homes to many species—birds, small mammals, insects—and create connected greenspace that sustains food webs and biological diversity. These areas also help with clean air, cooler temperatures, and managing rainwater, while giving people places to enjoy nature, exercise, and learn about the environment. The other options describe practices that harm the environment: industrial zones can fragment habitats and increase pollution, draining wetlands destroys important wetlands that filter water and provide habitat, and polluting streams degrades water quality and harms aquatic life. Hence, parks represent the positive impact in question.
