No. You could fit the entire population of the world in the continental U.S.

No. If it had, there would be no population growth.
The earth's carrying capacity for humans has been estimated at anywhere from 12-20 billion people. The development of sustainable technologies to increase crop yields could increase this number. On the other hand, global climate change - from either natural or anthropogenic causes - could cause it to drop significantly.

Carrying Capacity has a few different meanings. If your asking in regards to the total number of organisms the earth can support, then no. There is room and even food for billions more people, the problem is logistically getting this food to people.
If your asking in terms of comfort, as in, can the earth comfortably increase it's carrying capacity, then it becomes much more debatable.

not yet but it could soon be close to its cultural carrying capacity. - the maximum # of ppl earth can have w/o changing our current lifestyle
It is still a while before we reach the biological carrying capacity - the maximum # of ppl if ALL energy is put into growing food
I can't remember the numbers right off but we discussed this a while back in my Ecology class

What is these answers ? The carrying capacity is not at all changing .Only because of falling of meteorites it gets increased and because of chemical evaporation it is getting reduced. The population increase will not affect the carrying capacity.

Actually although our population is increasing currently the world fertility rate is decreasing. The latest number I heard was humanity would reach 9 billion and then population will begin to decrease. Also since our current technological innovations have created more efficient,although sometimes more destructive, ways of growing food we don't need to worry just yet about a famine.

The world has not reached its capacity. All the world's population could fit in the state ofTexas and not be as densely populated as the island of Manhattan in NY.

No we've not. the present estimates on the optimal human inhabitants that the Earth can help is 20 billion, even if it truly is trust that using nano technologies could develop that to 2 hundred billion. it truly is all about utilising elements properly.

If it really has then we should be having more unusual weather changes like a tiny sun and another ice age that actually arrived early

No. We have plenty of resources to support additional population. It's just that our resources aren't being distributed very well.
