In comparing the long-term impacts, which statement about resource management is PARADOXICALLY true?
- A. Aggressive extraction today ensures more resources tomorrow
- B. Stricter conservation today may cost economically short-term but provides greater economic and environmental security long-term
- C. Resources need not be managed because they are infinite
- D. Conservation prevents any economic development
Answer: B. Stricter conservation today may cost economically short-term but provides greater economic and environmental security long-term
While conservation requires initial investment and may limit short-term gains, it prevents resource collapse and ecosystem degradation, ensuring sustained prosperity and survival.
