Natural heritage value refers to biodiversity and its ecosystems with outstanding universal value inherited from past generations, maintained in the present, and bestowed to future generations.

• A. True
• B. False
• C. Partially True
• D. Not defined

Answer: (A)

Natural heritage value captures the idea that biodiversity and its ecosystems can possess outstanding universal value that belongs to all humankind, not just a local or national group. This value is framed as something inherited from past generations, maintained in the present, and entrusted to future generations, highlighting the duty of stewardship across time. The concept of "outstanding universal value" is a UNESCO designation, meaning the significance is so great that it is relevant to humanity as a whole, guiding protection and preservation efforts. Because the statement aligns with this widely used understanding, it is true. The other options would imply a deviation from or ambiguity about this established framing (false denies it; not defined ignores UNESCO usage; partially true misses the full scope).
