Answer:
C. There will be an increase in demand for access to basic goods and services.
D. More people are going to be living in poverty.
Explanation:
There are the two most likely consequences of this fact. As population in the developing world increases, there will be more people that will need access to basic goods and services. This includes a growing demand for food, clothing, natural resources, water, health care, jobs, pensions, etc. This would put great stress on nations that are already struggling economically. Moreover, as more people become workers, the demand for work will increase, and if this is insufficient, more people could end up living in poverty.
