however, not knowing your age i don't know if you have seen the space shrinking all over the world. sure, huge empty spaces - which we need if we are to have animals and vegetables survive with us (and until we invent good replacements that is essential) - but i remember when the world was about half as crowded as it is now.

If space and land use is what you wanted to debate you should have mentioned that not overpopulation.
Population has controls in place, its the same controls in nature.
Look at how many acorns there are and watch the Squirrel population explode the next year.
Only to decline once they outstrip there food source.
The human population is the same, yes the world population is steady growing. However we aren't at the tipping point yet.
Below is a population pyramid:
A near perfect population pyramid whould have a high population <1 at the bottom and low number of people >99.
This means as people get older they pass away and are replaced by a younger generation to replace them.
But, if you look at the US and Mexico population density together as a whole they just about balance out.
The American population will be made up of retires that will pass away and Mexico will have lots of young generation to replace the old lost.
Of course economical that means problems for both countries as one struggles to find economical medical care for an older population and the other tries to educate and find employment for a mass of young people.
I'm not hear to discussed economics, just point out how the population balances out.
Thats one control, starvation and disease in Africa is another.
If we were at a point were the earth could not sustain itself, the population should have collapsed a long time ago.
The earth can still sustain an increase population until at least 2030.
katatonic,
Its simple human geography there will places that will experience overcrowding,drought, disease and poverty.
Regions with high birth will be overcrowded.
While, other regions in the world that don't have these problems and will be underpopulated.
The real world is an unfair distribution.
Land usage is a different topic for example converting substitutable farm land to commercial properties and I think thats more of issue you should be debating, not population.
I have no disagreements on that topic there aren't any clear priorities on effective land use.
Maybe you should live in Greenland?.
Low population density and because there are glaciers, sufficient water.
Glaciers and aquifers is where 90% of the clean drinking water comes from.
Getting efficient water is a problem everywhere, doesn't matter where you live.
I think most Californians take for granted the amount of effort used to transport water in to the state.
