There is a carrying capacity for humans. This is because humans will eventually run out of Natural Resources and space.
oxygen carrying capacity is 1.34 ml of oxygen per gram of hemoglobin.... taking normal amount of Hb in humans as 15g/ dL , then oxygen carrying capacity for 100 ml of bood will be = 1.34*15 = 20 ml of oxygen approximately.

No, I don't think there is a carrying capacity for humans. Humans, like all organisms, can only sustain themselves and their populations by having access to the products and services of their environment, including those of other species and ecosystems. However, humans are clever at developing and using technologies; as a result they have an unparalleled ability to manipulate the carrying capacity of the environment in support of their own activities.
Although there is some limit, or carrying capacity, to the planet, the humans have not had a chance to find out despite the fact that our population grows exponentially.
Humans need to maintain enough space and resources to increase the earth's capacity for all species. They have to make sure that they and other people have enough to survive.
