参考答案: D
本题详细解析:
D Subsidies granted to cocoa farmers may guarantee them a fairer income, but it will only further encourage unsustainable production by causing increased deforestation. Market failure is corrected by implementing policies to raise the cost of production, and thus bringing the market equilibrium quantity closer to the socially optimum output: - Choice A will raise the cost of production for chocolate manufacturers and thus discourage production
- Choice B will increase the cost of clearing forest land and encourage more sustainable use of the common pool resource.
- Choice C will increase the costs of production for all participants in the supply chain and encourage more sustainable and equitable practices.
