Carrying Capacity and Thomas Malthus
Carrying Capacity � Carrying capacity, "K, " refers to the number of individuals of a population that can be sustained indefinitely by a given area. At carrying capacity, the population will have an impact on the resources of the given area, but not to the point where the area can no longer sustain the population.

Just as a population of wildebeest, algae, or deer has a carrying capacity, so does a human population
Human Carrying Capacity Humans are subject to the same ecological constraints as any other species (a need for nutrients, water, etc. ) � Humans also have some features that make them a unique species: � › humans have the capacity to alter their number of offspring, level of resource consumption and distribution. › While most women around the world could potentially have the same number of children during their lives, the number they actually have is affected by many factors. Depending upon technological, cultural, economic and educational factors, people around the world have families of different sizes. › Additionally, unlike other organisms, humans invent and alter technology, which allows them to change their environment. � This makes it hard to determine the Earth’s Human Carrying Capacity
