Resource Utilization as per Carrying Capacity means that any system can sustain a limited number of organisms on a long term basis.

In case of human beings, carrying capacity concept becomes more complex. It is because unlike other animals, human beings, not only need food to live, but need so many other things to maintain the quality of life.

Sustainability of a system depends largely upon the carrying capacity of the system. If the carrying capacity of a system is crossed, environmental degradation starts and continues till it reaches a point of no return.

In order to attain sustainability it is, very important to utilize the resources based upon supporting and assimilative capacity of all the system.

Consumption should not exceed regeneration and changes should not be allowed to occur beyond the tolerance capacity of the system.

Hence, resource utilization as per carrying capacity of earth is important for sustainable development.
