Does the Earth have a defined carrying capacity for humans?Introduction:Having a population size that is not dangerously large is the limit at which the population size population is acceptable and intended as carrying capacity defined capacity for human beings1. Population size and consumption can create stress on the environment through resources and social systems, causing a deterioration in the quality of life. However, some believe that resources can be created by humans and that not all of them need to be replaced and reinvented once depleted, so the availability of resources may not be declining after all2. Although population growth increases economic growth through additional investments in natural and renewable resources, consumption, population growth, and carrying capacity limiting factors will decrease the Earth's ability to support and sustain us humans. “Yes” argument: the hypothesis that food is the limiting factor as observed by Malthus in 1798, they do not grow as fast as populations. It becomes clear that limiting factors are of different types when considering other species. The limiting factor may be space, for example, where the availability of places to hide from predators may be limited for some species, such that the availability of nesting material may run out along with water in arid regions1. Nicholson states that an inactive state of population equilibrium can be achieved under constant environmental conditions through mechanisms sensitive to population density. As density decreases, intraspecific competition in a population increases, so that the surviving population grows faster and the dense population grows more slowly1. He proposes that density-dependent feedback involving intraspecific competition pushes a population toward stability at its environmental limits... half of article..., 37, 45-52.
