A population projection is a projection of what the future population of a place might look like. In order to estimate this, demographers study birth rates, death rates and migration patterns. This information is usually obtained from population census. However, a factor that does not play a role in this is the results of national elections.

D) 80 percent

GMO stands for genetically modified organism, and it refers to organisms that are the result of a process by which the DNA of one species is artificially forced into the genes of an unrelated plant or animal. When crops are modified in this way, they become more advantageous for humans. They can resist more diseases, endure harsher weather, become more nutritious or grow larger. A large percentage of the food we eat can be considered GMO.
