Answer 1

At present it is about 6.7 billion. Through the 20th century it was doubling about every 50 years.

1900 - 1.5 Bn
1960 - 3.0 Bn
2000 - 6.0 Bn
2007 - 6.7 Bn
2050 - 12.0 Bn ???

There is no chance of housing, feeding, providing power, water, employment and transport for all these people, while at the same time reducing our effect on the environment.
This exponential increase in our population has only become possible because of the development of technology and industry. Food production and distribution has barely kept pace with population growth, and it has only managed this because of the industrial methods of farming and food distribution. Most fertilisers and pesticides and by-product of the oil industry, so without it, we would be in deep trouble

Answer 2

About 6 billion.
It will continue to increase until there's not enough resources to feed everyone.

Answer 3

Earth can support a much higher population indefinitely, with the right technology. Earth cannot even support the present population with the wrong technology (like what we had in 900BC for example).

Answer 4

People get very nervous when you go below the belt
Mans sexuality and very often how many kids hes got is proof of his masculinity and insurance for old age
with many possible incomes to assist him when he himself cannot work any more
the second point is HOW do we ethically control populations

poor areas with less education DEMONSTRATE THE HIGHEST NUMBERS OF TEEN AGE PREGNANCIES,

educated women have less children
But uneducated populations are more religious and more resistant to birth control.
to forcibly control populations is frowned upon to say the least
So it is being done in sneaky ways
http://answers.yahoo.com/question/index;...
In the Netherlands after the war families were encouraged
to have few children because it is such a small country
not much bigger than Mexico city,
so it was physically impossible to fit a lot of people into the country ,There people can understand the concept of birth control,
But in larger countries many think like rabbits and think only of the family ,not the society as a whole

what happens if the country is full
wage war and kill everybody in another place to invade and settle there ,that would be the natural solution
In the past conquering countries encouraged the people to have many kids to be used as cannon fodder
or settling farmers needed many sons to provide labor,
one would have thought that we had progressed from that
But judging by the answers, many still cling to the old self centered or invasive philosophies

NATURES POINT OF VIEW

In Nature exists such a thing as the law of Harmony and Equilibrium
Some Native peoples have always been aware of this
to limit the tribes number to as many as the tribe can afford to feed
The Central Americans sacrificed the excess children,the earlier ones like the Olmec practiced birth control
Amazonian tribes have strict sexual rites that limit copulation in the conventional way.

Animals have lots of young when there is plenty of food ,and have little or none when the conditions are bad
when there is a plague of rabbits ,many foxes are born,
when there is no game lions ,and other predators have few cubs.

plants do roughly the same
All follow the LAW OF NATURE OF EQUILIBRIUM
everybody is welcome ,but nobody in excess.
we must co-exist on this planet and limit our numbers to our resources

All of Nature obeys these LAWS,but Humans put themselves above the LAW,and have bred themselves into a plague
It is a miracle that Nature has allowed us to get this far.

everything else is set upon by plagues ,disease or predators ,when they exceed their allotted quantity,or there are Natural disasters .

There are two moments in the existence of a specie when extinction is likely,
when there are two few
And when there are too many.

Maybe Gaia is trying to tell us something with Global Warming
Humanity should listen and beware
we are part of the same Eco systems
and subject to the same LAWS
whether we like it or believe it or not
