Which term describes developing strategies that prevent negative effects on the planet and ecosystems that can be supported indefinitely?

• A. Environmental sustainability
• B. Social sustainability
• C. Financial sustainability
• D. Optical properties

Answer: (A)

The idea being tested is environmental sustainability: developing strategies that keep the planet and its ecosystems capable of supporting life indefinitely. This means using resources at a rate that can be replenished, protecting ecosystems and biodiversity, reducing pollution, and shifting to practices like renewable energy, waste reduction, and responsible land use so future generations can meet their needs as well. Social sustainability, financial sustainability, and optical properties don’t describe this environmental focus—the first is about people and communities, the second is about economic viability, and the third is a physical property with no direct link to planetary health. So the best fit is environmental sustainability.
