             Another area where humans learned from the animal kingdom is the importance of moving with the seasons, or moving to best provide for their species. Human immigrating and migrating to new regions in order to support their family, or to stake a claim in locations to escape harsh environments, can impact growth in a specific area. Rapid growth in one given region can be detrimental to not only housing availability or conditions, but also resources available to feed all that reside there. .

             The health and welfare of people is in the balance if the consumption verses the accessibility to grow and harvest nourishing foods to feed the masses is not taken into consideration. If the majority of the world's population is starving and malnourished then disease and contagious infections very often may complicate this dilemma. Evaluating these factors to survive in diverse climates, having adequate food and water, and managing illnesses, will ensure the population of a given region will survive. If a growing nation is unevenly distributed then all these things, if not monitored, can destroy the stability of a nation.

             Although we may be able to adapt to certain living conditions, we can't adapt and survive if the resources are not available. According to Part two of the U.S. Population Policy, "one of the most fundamental aspects of the impact of population growth on the political and economic well-being of the globe is its relationship to food, natural resources and water". A huge factor here we need to start considering is the world's available fresh water supply. The world's fresh water supply is fixed. It is constantly being used and renewed through the Earth's natural recycling process. However, it should be noted that the available water is a limited resource. In fact, according to Population and the Environment the Global Challenge, "the supply of freshwater is finite, but demand is soaring as population grows and use per capita rises.
