Cross Breeds - should cloning extinct animals be allowed?

should cloning extinct animals be allowed?

please let me know? i need to know what you think of cloning extinct animals.

I think its bad, if these species would get extinct, it should be a reflection on us that we should change something to preserve them, not find "the easy way out" and just clone them back!
no.they had there time,its all part of evolution. what would be the point of bringing back a T.REX?
im unsure but can think of two pretty valid arguments, against - they are extinct for a reason and they are unable to live on our planet, so why create them to have them killed again? for - we can learn more about history and build a broader biological timeline of our planets animals.
Their extinct for a reason, I think let nature be.

No. Cloning anything is wrong.
No. Its not right to clone anything. Its just not natural.
NO, DID JURASSIC PARK NOT TEACH US NOT TO PLAY GOD?!?! to be honest i don't see a problem, though often it would seem pointless, except for man cuased extinctions
they should leave history as it is. good for research but BAD when the cloned animals turn on them (attack them like dinosaurs perhaps)
Mmmmm... dodo steak on rye with mayo.
If cloning one animal would save the entire human race or find the cure for cancer then I'm sure it would be seen as acceptable. However I wouldn't want to see cloned animals treated as an "expendable" resource. They would need to have good, happy healthy lives that did not result in them being killed by our hands.
I don't believe so. In theory, we must all adapt to survive, if you cannot adapt and evolve to the surroundings then the game is over. If we bring them back, what'll stop them from dying off again? But, this is the big but, humans have intervened so much. We have moved species from one habitat to another, changing the entire ecosystem so one animal may die out - think of the American Mink verses the English one, the normal mink we have is being killed off because some bugger set a load of American minks free into the countryside, these are smaller and faster and so they get all the best food and kill the indigenous mink infants in their nests. Also, going back much further, the Dodo. We killed that bird off from our hunting. But the bird died because it stayed on the land instead of flying or roosting in trees, and it had never seen humans or their dogs, so it wasn't afraid. If we bring it back, although it was us that killed it, it'll die off again straight away because, lets face it, it just isn't that smart! Tricky subject... perhaps in some cases we should, but in most cases we shouldn't.
Depends what it is really. If it would help our ecosystem i think it would be a good idea, as long as it wouldn't get out of hand. And not a repeat of bring something like the cane toad into Australia
i do not believe in cloning of anything
Wahey, absolutely who the hell would turn down the opportunity to see a T.Rex for example. All this `Let`s not play god` cobblers to that. I would love to see a 65 million yr old carnivore bite a lawyer in half. let`s live a little, bloody horrid sanitized nanny planet we all live on now.
It really does depend on what it is and how it fits into our ecosystem. If it's something that we're responsible for killing off and it's absence has a negative affect on our planet, then I don't see the harm in trying to correct our mistake. Here's a large hypothetical example. Emphasis on "hypothetical", but it makes the point. What would happen to our precious oxygen supply if we killed off all photosynthetic organisms? Your first biology course should have answered that. In such an extreme example, I think most people would be demanding that we start bringing back the photosynthetic species long before the last ones are gone and we run out of oxygen to breath. The point is that before proclaiming "no-never!", we have to look at the individual circumstance, the cause, and the impact. And no, not for the purpose of selling tickets to a dodo exhibit.
Perhaps one of the most controversial issues of the new century is that of cloning. One of the most popular arguments is the possibility that in the wrong hands, cloning technology could be used to replicate malevolent individuals such as Adolph Hitler. While Dino DNA could only have been extracted from blood inside mosquitoes that were preserved in amber to suit the story, it is in fact possible for us to get material from recently extinct animals to try and bring a species back. First off, the material must be extracted from an animal that has been dead for a maximum of 5 days, or if longer, the animal must have been preserved by being frozen immediately after death to preserve its cellular integrity. In order to bring back a rare Asian ox, the Gaur, Scientists infused a regular cow's egg with the genetic material of a living Gaur. If the technique had been successful, it could have been used to repopulate extinct species, or strengthen the ranks of those on their way to extinction. If implanting eggs which were taken from a host animal with the DNA of another animal for the purpose of its acceptance by the host body's immune system produces similar results every time, maybe the implanted embryo's immune system fails to develop as that of a normal fetus.
Personally i don't think so. The reason animals become extinct is the proof that survival of the fittest does exist... The unfit are unable to survive and fight for themselves in order to continue life, therefore they become extinct. What would be the point in wasting time and a lot of money to bring back animals that can't survive?!... Therefore, personally, I don't think extinct animals should be cloned back to earth!
i think cloning is bad because after they clone the animals there going to start cloning humans and then thats just crazy
Nope they are extinct for a reason! Many recent extinctions because of habitat loss or factors associated with this. So where would we put them? Whats the point of bringing something back to life just to keep it in a zoo/equivalent? Its all about survival of the fittest!
When you said this, the first thing I thought of was JURASSIC PARK, I now its just a film but imagine ... curiousity killed the cat. I don't think we should clone extinct animals because we don't know what they are capable of, aand what they eat. Surely, by creating dinosaurs, they will eat more animals and eventually our ecosystem will just be screwed up?
I would be very interested in witnessing a revival of an extinct animal. I hate the term "playing God", why use it when every day all we do is trying to extends our lives by playing god. Why do we go to the doctors? Why do we get surgeries? Why do we invest our money and time for scientist to find new cures? Cloning can lead to new scientific breakthroughs. If we don't give it a chance, then Species in this world (including humans) has a higher percentage of dying at a quicker rate. I want to see cloning done to an extinct animal. They deserve to be brought back, wouldn't you want life mysteries solved?
If the animal became extinct due to human activity, then I think that cloning those animals should be allowed. The local ecosystems will be better off for it. For example, the Tasmanian tiger I reckon if the technology evolves to such a level that that species should be brought back. If the animal became extinct due to natural activity, such as the Dodo or Mammoth... then I don't think they should be cloned.
i think they should
