I think, Yanny, you are right on using stem cells to grow organs alone – but wrong on the next nuke war as a population-buster. I don’t see the global thermonuke holocaust (like the US-USSR Cold War-Dr. Strangelove scenario) happening. {knock on wood} I see an exchange of fewer than 10 nukes, and not between superpowers… 50-50 chance one or more superpowers does take part, but not directly against another superpower.
(by “superpowers” here, let’s suppose I mean US, Russia, China, UK, France :::: the major nuke stockpilers)
So who else does that give us, looking only two or three years down the line:
India, Pakistan, NKorea, SAfrica, Israel, certain of the former Sov republics that have supposedly disarmed, various non-state organizations, some nation or non-nation based in South America, Africa, Europe, Asia - - - and of course::::: CANADA!!!
Anyway, not enough to cause nuclear winter, not enough to make much of a dent at all in human population, but more than enough to give just about everyone a really rotten day.
Now here’s an ax to grind: the non-weapon nuke power reactors around the globe… I see a meltdown due in a country other than US (TMI) & Ukraine (USSR at time of Chernobyl). The real nuclear war is ongoing punishment of air, water, wonderful dumb animals, plants, and those mischevious human beings who insist on digging up, concentrating, enriching and dispersing uranium and plutonium to the four corners of the world.
Why a new meltdown? Well either we must assume that in the years that have passed since TMI & Chernobyl, most nuke power facilities around the world have been really professionalized and hardened vs. negligence, accident, terrorism, etc. … or that most have not. If the latter is true, I think it is just a matter of time, and I could be wrong about all of this but I don’t think terrorism will be the cause – more likely to be corporate greed and negligent safety, construction & maintenance procedures and practices.
This is well off the subject of cloning. But it certainly has to do with population pressure. All I know is, the expense of building a billion windmills, and the human and property cost if they all fell down… well, it would have to be less than one single Chernobyl. Clone solar!
