The Population Reference Bureau has projected that in 2011, the planet Earth will be home to more than seven billion living humans. At current growth rates, we'll top 9 billion in 2050. By that year, the population of Africa is expected to double, and that of Asia to grow by 1.3 billion.
The world's population is growing unevenly too, the projection states. In a continuing trend, economically developing countries are growing faster, while the populations of developed nations are aging, and their workforces diminishing relative to their elderly populations.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.

Everyone start having lots of babies!
Nostradamus predicts the opposite. By the end of this century the world will be under populated. That would be less than 100 million. First event we should expect is the genetic bomb .AIDS failed because the time delay was too short.The next one will be externally triggered after a long time delay.
Humans like their intercourse!
sam6302 this expectation/prediction is ridiculous. And how does AIDS have anything to do with it? AIDS never could or would have had such a drastic effect on population size. You need something like the plague or the 1918 influenza pandemic, fast acting and easily spread. What exactly is a 'genetic bomb'?
Well sam6302 doesn't seem to be the sharpest knife in the draw but i think i can unscramble what he is trying to say a little bit. With regards to AIDS he is talking about a overhyped conspiricy that is nearly impossible to believe. Supposidly it was man made to wipe out large volumes of the planets population. Although this is nearly certainly not true, there is some potential in what he is saying. It is likely that AID's was initially man made as it has a structure that is not found in nature, although for what purpose noone knows and there are also man made biological weapons that are designed to reduce population. If you look back through history, in the 1950's the amaerica government tested out biological agents on small samples of the general public without them knowing. the purpose of the experiment was to see if they could steralise humans. (not something that is commanly known but it has officially been released by the american govenment now. Another huge concern is DNA tuned biological weaponry. It is potentially possible (very likely even) that biological weaponry can be created that target different ethnic groups. Quite a worrying thought, they may also have the potential to spread through
:- contact, water or even airborn means. Either way, the technology is nearly at a stage where it is testable in some laboritories worldwide. not for this purpose (officially) but with the potential for many uses. I dont have references to hand but if you dont believe me, im sure a few google searches will throw up heaps of evidence for all i just said.
