As the world's population approaches seven billion people, some fear that Earth's citizens face a catastrophic food crisis in the near future. Furthermore, experts place the globe's population in 2050 at more than nine billion, a potentially overwhelming figure for the world's resources. Some worry how everyone will be fed as land, water, and other natural resources become more scarce. Others are concerned that not everyone will be able to afford food, and starvation may take hold of the world's population. However, some scientists are more optimistic, believing that the hunger problem will be erased from the planet by 2050. "Feeding a Hungry World" explores the problem of world hunger, how experts propose to cure this problem, and what booming population growth means for the future of food.
