It is difficult to calculate the Earth's carrying capacity because there are lots of resources that we can use and their is so much land on the earth that hasn't been used, but at the same time some resources are running low, and some resources we have a lot of, like food, so that it is why it is difficult to calculate
The maximum members of the population of species that can be supported by the environment on the basis of the existence of resources is considered as the carrying capacity. It is not easy to determine the carrying capacity for human beings on the planet Earth, as the population of human beings is increasing exponentially on the planet Earth. Due to their intelligence and tendency to resolve the issues associated with the lack of resources, it is not easy to find the carrying capacity of human beings.
