... where are you going to get land for more farming without completely wiping out the ecosystems when our population gains another billion?
Ok, here are my water questions...
Where does it go?
Why can't we get it back from there?
I ask because it's my understanding that unless we shoot something out into space it's here... somewhere.

Water is not the problem. Its fresh unpolluted water that's the problem!
Ok you answered the first question, why can't we get it unpolluted again?

We can, its just that its costly and inefficient. We haven't (that I know of) developed a technology that will purify large amounts of water effectively.

Hmm... ok, then charge what it costs and when it gets to be too much people will cut back until things go back into balance.

One of the things is the rest of the world, particularly the 3rd world doesn't protect its fresh water, doesn't have the resources to adequately purify their water and many of these countries reproduce like rabbits!
I don't mean to sound harsh, but they will do what they do and sooner or later balance will be restored. It will work that way whether we like the results or not. In CMM's description of how water could be unaffordable, yes, people will suffer, but when there is no way for people to pay more someone will come up with a way to sell it cheaper, or people will find ways to conserve more, or consume less. It will eventually balance because it has to.
No. We are not even close to any sort of critical tipping point. There are still an abundance of resources, and human ingenuity is making those resources either less relevant or more efficient. There are still vast expanses of this country which are virtually empty.
Farmland is not empty, and we need at least a functional ecosystem to survive, so technically that's not empty either. Don't think the deserts count either, if we covered most of them with cities (what few areas can actually have permanent structures) then we are not only still destroying an ecosystem we are also upsetting the natural environment. It's short sighted to think that just because there are still areas without big cities that there is a "lot of empty space".
most of the info on this is biased and way too subjective. what the fuck is inhospitable? we are looking into space colonies yet earth is inhospitable?Main article: List of countries by population density
For humans, population density is the number of people per unit of area usually per square kilometre (which may include or exclude cultivated or potentially productive area). Commonly this may be calculated for a county, city, country, another territory, or the entire world.
The world population is 6.7 billion [1], and Earth's area is 510 million square kilometers (197 million square miles)[2] . Therefore the worldwide human population density is 6.7 billion ÷ 510 million = 13.1 per km² (34.0 per sq mi), or 44.7 per km² (115.5 per sq mi) if only the Earth's land area of 150 million km² (58 million sq mi) is taken into account. This density rises when the population grows. It also includes all continental and island land area, including Antarctica. Considering that over half of the Earth's land mass consists of areas inhospitable to human inhabitation, such as deserts and high mountains, and that population tends to cluster around seaports and fresh water sources, this number by itself does not give accurate measurement of human population density.
Several of the most densely-populated territories in the world are city-states, microstates, micronations, or dependencies. These territories share a relatively small area and a high urbanization level, with an economically specialized city population drawing also on rural resources outside the area, illustrating the difference between high population density and overpopulation.
Cities with high population densities are, by some, considered to be overpopulated, though the extent to which this is the case depends on factors like quality of housing and infrastructure or access to resources. Most of the most densely-populated cities are in southern and eastern Asia, though Cairo and Lagos in Africa also fall into this category.
City population is, however, heavily dependent on the definition of "urban area" used: densities are often higher for the central municipality itself, than when more recently-developed and administratively unincorporated suburban communities are included, as in the concepts of agglomeration or metropolitan area, the latter including sometimes neighboring cities. For instance, Milwaukee has a greater population density when just the inner city is measured, and not the surrounding suburbs as well.
