If the human population diminished rapidly, would we have to clone ourselves?

not unless we had less than 200 people

I believe that we will keep evolving. Because humans are now on the verge of controlling their DNA, probably we could soon direct our own evolution instead of letting nature do it by natural selection. Also, there is a great possibility that humans may merge with synthetic materials , machines, and artificial intelligence, to create a Homo Roboticus, or cyborg.

One of the major problems with most transplant procedures is acceptibility. The patient's body recognizes the new organ as an intruder or threat, and attacks it.\nA cloned version of yourself would theoretically be a source of completely acceptable organs, since they are, in essence, your organs, genetically identical. Of course, you'd be killing another sentient being to harvest these organs, so there's the morality issue.\n\nHuman ingenuity has always been directed towards two opposite goals, saving lives, and destroying them. The other likely reason for cloning humans is for war. Identical soldiers, genetically modified to increase their physical prowess, dexterity with their weapon, and willingness to follow orders. Why send thousands of skilled laborers, with families and children, to their deaths when you can have a clone army grown specifically to be cannon fodder?\n\nI'm sure you could think of a few more reasons, if you really thought about it.

yes but we screw it all up - evelutionary caches (ie the aboriginies of austrailia) if left alone would eventually differ enough to become a separte species - for better or worse. but with world travel this is very unlikely to happen.\n\neven moreso with modern medicine we are hampering the natural selection process and genetic inferiority and deformity are not lost (i know this sounds heartless but nature has its own plan) we keep the week and infirm alive and in many cases protected form certain natural demise.\n\ndo I believe evelution is at work... yes but in humans its sort of devolution :S\n(sorry went on a rant :P)

I don't think so. If God didn't want us to clone, he wouldn't have given us the brain power to do so.

Actually the answer for cloning is also no. If we were to clone a human the baby would not grow in a lab. The embryo would still be implanted in to a women just like baby's being born via in vitro fertilization.

I think they will. But humans will all (or mostly) be extinct by then. There's the controversial theory that robots evolve over time and they technically can't die, because they were never alive. So even if humans killed each other off or in some other way became extinct, robots would still be around. And if the evolving theory is true, they will be able to function on there own, as they see fit - maybe acting as humans do. They might form governments, fall in love, etc. If this ever were to happen, I think it would be a long, long way into the future.

A human clone, if succesful, is just a twin of the original person (but younger).  That's seems morally legitimate.  But today the success rate would be very low; some of the failures would be horrible birth defects.  So it would be unethical to attempt cloning a human today.  Eventually, if it could be done reliably, it would be ethical (but getting there from here seems awfully difficult).

It may never happen, frankly; a lot depends on the work being done on isolating autologous stem cells from this or that tissue; apparently there are viable stem cells that can be harvested from bone marrow, and possibly from the skin.  If that comes to fruition, embryonic stem cells won't be needed.\n\nOf course, if we could ever figure out how to dedifferentiate cells (theoretically possible, but not yet demonstrated), then redifferentiate them, the whole field would be dramatically altered.  I'm figuring that the autologous stemcells will be available first...\n\nAlso, not all of the diseases targeted are necessarily dreadful, nor are all dreadful diseases amenable to stem cell solutions.

Not with current freezing techniques. Too much cell damage. In the future I think that a process will be possible. Will it be ethical or moral in a rapidly overpopulating world will be the ultimate question.

Do you want a nice answer, or a brutally honest one?\n\nIf former, then simply by stopping reproduction between people in certain places for a generation, causing people to die of old age without carrying on their line.\n\nsince this obviously won't happen, here's the latter:\n\nA global thermonuclear war, total exchange of 20,000 megatons or more, would kill enough people to cut the population in half, depending on the targets involved, the amount of fallout, and the length of the nuclear winter; that would pretty much stop all of this exponential growth, because people would most likely be more worried about staying alive than sex.\n\nNote: this is assuming that a species is intelligent or is living close to an intelligent civilization.

Yes, we could. We all will probably die at some point. As far as a mass extinction is concerned, who knows? The future is pretty much unwritten.

yes i would, i think our planets resources are runnig out fast so i'd wellcome anything that slows this down but that all we can do .

As said earlier - HUMANS\n\nas we consume resources and increase population without any control limits. \nand modern humans seem to have lost any self-preservation instinct that might leave a viable eco-system for their off-spring

Then it would no longer be artificial. Rather do a lot of humans have any intelligence to control with?

Here are some ideas for you:\n\n"Decline in genetic diversity. \nTaking nature into our own hands. \nReligious and moral reasons. \nPhysical problems, such as birth defects. \nPossibility of mental and emotional problems of the clone. "

nope...resources are being consumed and very little left.no more space for more human species.its very hard to live since poverty is present in any sides of the world now.miserable lives arec waiting for 95% of the newborns....just think about the world situation
