What does the positive role of carbon dioxide in vegetation growth and its possible negative climate role show?
Answer and explanation
Correct answer: The role of the same gas can change according to context
The governing concept is context-dependent environmental impact. Plants use carbon dioxide as a raw material in photosynthesis, helping produce organic matter and release oxygen. However, an increased atmospheric concentration strengthens absorption of outgoing longwave radiation and can contribute to warming. Therefore the same gas may be beneficial in one biological process but harmful in excess; the absolute claims in B, C, and D are false.
