Which of the following is not a factor that is increasing the risk of a widespread famine before 2050? a. water scarcity b. overpopulation c. agricultural shift to biofuel production d. increased crop diversification

The correct answer is - D. increased crop diversification.

The increased crop diversification would not lead to famine, but instead it is a very positive measure that can contribute significantly to stopping such a thing from happening.

Be it with selection, or with using the newest of the genetic technologies, the crops can be improved and diversified, so that they can be grown in places where the conditions are not ideal. With this kind of measure, much more land that now seems to be not suitable fro agriculture can be used, thus the production of food can be significantly incresed in multiple regions of the world.
