Answer:
1. True
Step-by-step explanation:
The predicted response to increased production of greenhouse gases is a significant point of controversy in the climate change debate. While some argue that the effects will be catastrophic and require immediate action, others say that the science is not settled and that the economic costs of reducing emissions would be too significant.
Answer:
2. True
Step-by-step explanation:
The production of ozone-depleting substances, such as chlorofluorocarbons (CFCs), can be modeled as a negative externality because the costs of producing these substances are not borne by the producers alone, but are instead spread across society in the form of the reduced ozone layer and increased skin cancer rates. This is an example of market failure, as the actual costs of producing these substances are not reflected in the market price.
