Evidence of carrying capacities?

Question

What evidence indicates we (the world) have reached, or exceeded our biophysical carrying capacity? What about our social capacity?

Answer 1

Well, if we exceed our biophysical carrying capacity, we would have mass starvation. That hasn't happened yet. It would imply that all arable land was in peak production. All potable water was being consumed. All breathable air was being consumed.

Our social capacity was breached when two groups couldn't live in the same place and not kill each other. That was passed a long, long time ago.

Answer 2

i do no longer think of that the logistic form of inhabitants enhance - from which the theory of a wearing skill arises - is a superb form for human populations. people are unique between animals for his or her large skill to alter their ecosystem. cutting-edge people have changed Earth to extend its human wearing skill. although, those changes are no longer all sustainable indefinitely. wearing skill for people for this reason comes with a time scale. we are at the instant helping very almost 6.8 billion human beings, yet will we proceed to achieve this for, say, 200 years? I doubt it: inevitable shortages interior the factors that we use to maintain this inhabitants - noticeably petroleum and phosphate minerals - willpersistent the inhabitants down. With greater populations, the topics develop into greater acute: factors would be depleted swifter, and the inhabitants isn't supported for as long a time. So the question is particularly no longer in basic terms "how many," yet additionally "for a manner long." With contemporary inhabitants ranges, i think of this time is probable a century on the very maximum.
