Which term describes a way of using natural resources without depleting them and of providing for human needs without causing long-term environmental harm?

• A. Conserve
• B. Sustainable
• C. Renewable
• D. Balanced

Answer: (B)

Think about meeting today’s needs without compromising the ability of future generations to meet theirs—that's the essence of sustainability. It describes using natural resources in a way that doesn’t lead to depletion or long-term harm to ecosystems, while still supporting human well-being. This is why sustainable is the best term: it explicitly includes both avoiding depletion and preventing long-term environmental damage. Conserving focuses on protection, but not the ongoing use aspect; renewable refers to resources that can replenish, which is related but doesn’t alone ensure sustainable use; balanced implies harmony but doesn’t by itself guarantee long-term environmental protection.
