/bug my point is that certain extremist community's population figures are continuously increasing... even if they are less powerful today.. but what will happen when they out number us?

also, we are in a way to neutralization of our nukes...

how do you and what future you see in this scenario ?

This is a pretty astonishing video. I have never thought the world was overpopulated. The whole world population can actually fit in France with room to spare. It seems pretty clear from the video that the world population will probably plateau somewhere between 9 or 10 billion in the future.

This is outright flabbergasting: The 7 billionth baby born today?
When estimating the global population to reach 7 billion, there is an error margin of at least 1%, for no one can arrive at an exact figure of world’s total population at any definite time, given the myriad of factors beyond one’s control.

Granted that there will be 7 billion people before the end of 2011, it is still impossible to fix the exact date, let alone the exact second when thousand babies could be born. Now there are already multiple claims of the 7 billionth baby born in Russia, India, The Philippines…, just name it. How stupid! (btt1943)

The last sentence "It will be a more crowded but more stable world" is poorly worded: the population may possibly be more stable - but a number of factors suggest that the world is less likely to be stable due to a reduced capability to support such a population:
- climate change in particular is likely to reduce food crop yields due especially to drought (e.g. Nature article on "dust-bowlification"), also flooding
- loss of food-crop land-area to biofuel-crop land-area to feed vehicles of those increasing climate change instead of mouths of poor people suffering from results of climate change.
- lower food productivity due to increasing desire for meat.
- the failure of "the 1%" to have any concern for negative externalities (eg climate change impacts) that don't directly affect the 1% ...
- continuing failure of Governments to do what needs to be done re the above - as they have been "bought" by the 1% i.e. corporations and "The City" interests - whose main concern is to make profit regardless of the concerns of the planet etc etc
FT's Martin Wolf addresses some of such problems in his summary text for his forthcoming lecture (3nov11) at my old Uni: Imperial, London

In the Belly of the Beast

Every time they have tried to predict the future, scientists and population 'experts' have gotten it wrong.

"Too many people!" "Global Cooling!" "Global Warming!"

So look at their predictions, and then decide for yourself what will happen, because YOU live on the ground, and these academic idiots live at a university interpreting numbers collected by governments.

And we ALL Know how good government is at....well, nothing seemingly. Unless you count ruining the greatest economy in the world something.

Would it seem out of the question to think that an ever increasing population may be a strategic goal when considering the exploration of Mars and beyond? I know it seems silly, but dont we need lots of folks if we trully intend to explore and someday colonize our galaxy? Or is this all science fiction fantasy?

Overpopulation (demographic problem) of the planet, is an even bigger issue than global warming. And what is really worrying is the fact that we as humankind, haven't concerned yet ourselves with the implications.
The generations that draw breath now on this planet, show a profound indifference of the future that awaits their children.
The chain of events to come are as follows,
overpopulation leads to the exhaustion of natural resources, which leads to conflicts for those depleting resources, which in today's world means global war, which leads to the change of fundamental beliefs (religion, economic theories, etc) and the extinction of the world as we know it.
The middle-ages will be a walk in the park for humanity, compared to this.

I've learnt not to believe the projections from the UN. The so-called "replacement rate" is a function not just of the birth rate, but also the death rate, and the methods the UN uses to forecast both of these are laughably simplistic, taking no account of advances in medicine, contraception, and so on. In fact, each time the UN revises its estimates, it modifies upwards - for many countries - its forecasts for life expectancy. The most accurate forecast would take into account these sequential upward revisions within a single forecast.

now its the time to control world population by use war to decrease the growth of human because too many human too many mouth to feed on and too many job insurance and burden to all country all around the world thats why war in lybia cyprees chaos in greece is benefit to us all because more people die less food dress and house to give to them thats why war always happen because human always need better work better food better home and thats why we cheat we corrupt we kill each other because the most important is ourself our family our country and that why we have to control population by any means neccesary even it is war to other country to take oil resorces and land like israel and philistine thats why war is always happen in all culture and history we need war to make better land better food and better home and better future for our children and grandchildren

I see this leading to significant problems in the near future. As a prospect economist in college, the first concept we learn is "resource scarcity." Although the world can fit 7 billion people (or possibly more), the world is not prepared to sustain such a large population. We are lacking food and other necessary resources in several under developed countries. At the rate that we are heading now, world population is going to be a huge issue that we will juggle in the next few decades.

Betty Chambers

So what? Most people live in mega citizens and on only 3% of the planet's livable surface, if not less. The entire population on earth could comfortably fit into California or Texas or Florida. The population "crisis" is much ado about nothing....

Goncalo Braz in reply to Betty Chambers

Let me see if I got this right. People only need 3% of the world's surface to live, and a about 16 500 people/km^2 is comfortable.
Betty do you live in a wooden house, with a backyard, powered by electricity? I bet you chopped up a square meter of wood and drilled oil from right under your heels, to build your house, power your lights and get you to work, no? Have you ever had any contact with something called education? Or do you just live under your "selfsustaining", "comfortable" rock? Cause I really don't see why people are spending their time and effort chopping down the world's forests, fighting for oil, polluting water and air, converting land to gmo monocultures, fracking for natural gas, etc, when we could all just go hang out in one of those states. Everyone must have lost their minds!

It's odd to see that specific countries are dropping so drastically in birth rates. I wonder how governments will react to their eventual decrease in population. With a decreases in population, more jobs and space is available, making for more comfortable living environments. Times are changing where nations no longer need mass amounts of workers or troops to fight wars, technology has replaced the roles of the masses. This makes over population an unwanted pain that clutters the cities all over the planet. On another note, I find it hard to believe that the worlds population will ever begin to decrease. This may only happen if governments begin to control birth rates due to limited resources or supplies. When population is regulated, I can see a drop happening, however this may not happen for quite some time.

The message of the video clip is that, finally, the rate of the world's population growth is declining. So the fear that keeps me awake nights, that we will reach 8 billion, 9 billion, and so on, at ever faster rates, proves to be unfounded. Is this one of those things that people got right?
