Answer the following question given this paragraph: People themselves are also affected by the large size of the human population. Some people have a lot; some have very little. Many people refer to the abundance of luxury items in some people's lives as over-consumption . People in developed nations use 32 times more resources than people in the developing countries of the world. The symbol of this is CO 2 emissions, which are a waste product from fossil fuel burning. Populations that burn the most fossil fuels have a high standard of living. Q: What is a waste product from fossil fuel burning? A:

OPTIONS:
