<Dd> A is the consumption per capita (affluence) </Dd> <Dd> T is the technology factor </Dd> <P> An important model related to carrying capacity (K), is the logistic, growth curve . The logistic growth curve depicts a more realistic version of how population growth rate, available resources, and the carrying capacity are inter-connected . As illustrated in the logistic growth curve model, when the population size is small and there are many resources available, population over-time increases and so does the growth rate . However, as population size nears the carrying capacity and resources become limited, the growth rate decreases and population starts to level out at K . This model is based on the assumption that carrying capacity does not change . One thing to keep in mind, however, is that carrying capacity of a population can increase or decrease and there are various factors that affect it . For instance, an increase in the population growth can lead to over-exploitation of necessary natural resources and therefore decrease the overall carrying capacity of that environment . </P> <P> Technology can play a role in the dynamics of carrying capacity and while this can sometimes be positive, in other cases its influence can be problematic . For example, it has been suggested that in the past that the Neolithic revolution increased the carrying capacity of the world relative to humans through the invention of agriculture . In a similar way, viewed from the perspective of foods, the use of fossil fuels has been alleged to artificially increase the carrying capacity of the world by the use of stored sunlight, even though that food production does not guarantee the capacity of the Earth's climatic and biospheric life - support systems to withstand the damage and wastes arising from such fossil fuels . However, such interpretations presume the continued and uninterrupted functioning of all other critical components of the global system . It has also been suggested that other technological advances that have increased the carrying capacity of the world relative to humans are: polders, fertilizer, composting, greenhouses, land reclamation, and fish farming . In an adverse way, however, many technologies enable economic entities and individual humans to inflict far more damage and eradication, far more quickly and efficiently on a wider - scale than ever . Examples include machine guns, chainsaws, earth - movers, and the capacity of industrialized fishing fleets to capture and harvest targeted fish species faster than the fish themselves can reproduce are examples of such problematic outcomes of technology . </P>
