For a given region, carrying capacity is the maximum number of individuals of a given species that an area’s resources can sustain indefinitely without significantly depleting or degrading those resources. The carrying capacity may be lowered by resource destruction and degradation during an overshoot period or extended through technological and social changes.For example, a pond inhabited initially by ten turtles will be sustainable for the species’ population. Because water, food, and space abound, the turtles can thrive and reproduce at an exponential rate. However, as the population grows, competition is intensified as well. Turtles compete for food, water, and space.
