The carrying capacity of an environment is the maximum population size of a biological species that can be sustained by that specific environment, given the food, habitat, water, and other resources available.
Authors such as Buckley, Wagar, Washburne, McCool, and Stankey have critiqued the concept as being flawed in both the conceptual assumptions made and its practical application. For example, the notion of a carrying capacity assumes that various elements, such as the social-ecological systems in which tourism destinations are situated, are stable.
A species population within a specific habitat exceeds the carrying capacity, for example national parks reducing herbivore populations to maintain and manage habitat equilibrium. The entire equilibrium consisting of animal and plant organisations is already out of balance, for example existing populations colonising new habitat.
A pack animal, also known as a sumpter animal or beast of burden, is a working animal used to transport goods or materials by carrying them, usually on its back. Domestic animals of many species are used in this way, among them alpacas, Bactrian camels, donkeys, dromedaries, gayal, goats, horses, llamas, mules, reindeer, water buffaloes and yaks.
A bag limit is a law imposed on hunters and fishermen restricting the number of animals within a specific species or group of species they may kill and keep. Size limits and hunting seasons sometimes accompany bag limits which place restrictions on the size of those animals and the time of year during which hunters may legally kill them.
Sometimes payload also refers to the carrying capacity of an aircraft or launch vehicle, usually measured in terms of weight. Depending on the nature of the flight or mission, the payload of a vehicle may include cargo, passengers, flight crew, munitions, scientific instruments or experiments, or other equipment. Extra fuel, when optionally ...

Since global hectares is able to convert human consumptions like food and water into a measurement, biocapacity can be applied to determine the carrying capacity of the Earth. Likewise, because an economy is tied to various production factors such as natural resources, biocapacity can also be applied to determine human capital. [12]
