Designed to foster an understanding of some of the relationships among population growth and distribution of people, food, and land area, this simulation kit deals with the following concepts: (1) the finite nature of land and resources, (2) the size and rate of growth of population, (3) the unequal distribution of population throughout the world, and (4) the distribution and consumption of world food supplies. Section 1, "Simulation," contains three main parts: "World Population Growth,""Distribution of World Population and Agricultural Land," and "Distribution of World Food." Each simulation actively involve all participants. For most of the activities, a large floor space is mapped out into six major world regions. Participants are distributed among the regions according to the regions' percentages of world population. Participants act as citizens of their respective regions during the simulation. A discussion guide at the end of each part can be used to elicit factual information, opinions, and feelings. Optional activities are also included and may be used to explore concepts such as migration, family growth decisions, and protein consumption. Section 2, "Resource Materials," provides the necessary geographic and population information for all activities. Contents include a glossary, regional population and geographic information sheets, a script for the combined version of the simulation, world and U.S. population charts and fact sheets, and world population data sheets.
