Carrying capacity in ecology refers to the level of land or resource use both by humans and animals that can be sustained over the long term by the natural regenerative power of the environment. Sustainable development is economic activity or growth with due consideration given to carrying capacity and which does not reduce or deplete the resources available to future generations. Current growth and consumption patterns are placing increasing stress on ecosystems ignoring the carrying capacity. Environmental degradation, biodiversity loss, deforestation indicate that ecosystems are stressed and the carrying capacity is being compromised. Human population is above the long-term carrying capacity and is maintained by the exploitation of fertile soils, fossil fuels, and ground water.
According to the concept of carrying capacity a finite number of people can be supported without degrading the natural environment. The concept of carrying capacity of an ecosystem for natural populations is derived from the logistic growth curve in population ecology.
