We will and we should bring back extinct species to life. When cruel humans have made them extinct , then why not 

the good scientists try to revive them back, it will be a good karma. But, i also say that we should preserve and 

take care of current species. If i was to decide i would also bring dozens of T-REX and Smilodon back.

People can say all they want like, "This is a bad idea".  Truthfully it's our fault half of these species went extinct in the first place.  This makes it our responsibility to mother nature to bring them back and undo the damage we've done.  Anyone that wants to say this is "playing god", we were playing god when we decided to wipe thylacines, passenger pigeons and the carolina parrot off of the earth.  So ya lets bring them back to life.

The De-Extinction arguement is a very fine line to walk on.

There are arguements for both sides of the arguement. For example, releasing creatures created from sequenced genome's could be classed as 'less natural' then those found from frozen cells, so maybe considered as genetic experiments. It is also true that the possibility of De-Extinction could devalue the importance of conserving remaining species that we already have.

However, there are plenty of reasons for supporting De-Extinction. Like the article states, the species that could theoretically be brought back only went extinct when Humans started to have a serious impact on the environment, so between 20,000 to 10,000 years ago. Also, the whole notion that we would be playing God when resurrecting these creatures folly, considering that we chose to wipe out many with that specific intention.

Also, many endangered species now have DNA stored into frozen banks, which is little different from many attempts at De-Extinction, and face much less opposition. It seems that many popular arguements against De-Extinction stem from films and novels such as Jurassic Park.

So overall, De-Extinction should be embraced as a method for future conservation, but not without a definite certain amount of caution.

Better animals than humans-DO IT! 

Considerations, First, it won't work the first or possibly even the first 100 times, so have grandma's credit card ready! Second, 2 different clones of the same species produces something that isn't a clone. Third, Who owns the patent? It won't be the public, it will be some company, country joint ownership. Why does that matter...b/c the company will probably go bankrupt, the country will end up in a recession, depression or more often some war....war always comes. Then the poor animal is put down and ends up stuffed in a museum behind a wall of plexiglass-go figure! Food for thought. :)

WE should try and save the animals that are going to be on the new extinct list NOW! Not animal from 10000 of years ago. Were they will not survive in this environment. Protect what we have now. Put it to good use to save the tigers, elephants, rhinos gorilla etc....

It is not our place to resurrect extinct animals, they had their place in time and now that time is gone. It is also not our place to create new species, that is Gods territory. What is the purpose or the benefit of trying to resurrect the Mammoth? It will not be the true animal and it will only prove that we can manipulate DNA but, we can already do that. The mentality that we should just because we can is stupid. It is simply an act of arrogance that will soon come back to bite us in the a**.

I found this article fascinating despite the mountain of ethical conundrums that are intertwined.

We should first resurrect the saber toothed tiger . It would eat a lot of humans and make room for the woolly mammoth. The teeth of the woolly mammoth look like a bulldozer so it could bulldoze the humans away to make room for itself. While doing so, the humans could de-extinct all the other species which could then go on revolt against the humans until they are endangered and go extinct. The ultimate human sacrifice to save the planet as it once was, before homo sapiens destroyed it with what it considers intelligence.

So what will we do with them when they are brought back?Most of their environment disappeared along with them, and most of them died out due to loss of habitat or because of climate change.As example, the wooly mammoth would sadly be in a hell of Man’s creation.It doesn’t belong here anymore.It has no place in today’s world.So why?...just because we can?That’s unacceptable, irresponsible, and inhumane.For scientific study?That’s also unacceptable.The argument that we would have a chance to redeem ourselves and assuage our guilt for their loss doesn’t work.Yes, they went extinct because of us, but bringing them back would be like trying to glue a broken mirror back together and expecting to see a perfectly recreated image.They would be miserable, or they might proliferate to the endangerment of today’s species.On the other hand, to keep them alive and in isolation merely for scientific study would be unconscionable and to keepthem in zoos would certainly be that hell on Earth.We should be more concerned with how we can protect the many species that are in trouble here and now.We should concentrate on preservation, not resurrection

Hey everyone, I apologize my self,  for my english writing. Its not my first language.

So anyway.

If you are going to introduce a mammoth  into the wild, you have to considerer in an extensive and thorough investigation, of how is going to impact a new specie to the environment and to the rest of the fauna and flora.

Throughout time, the nature it self has created a perfect balance between species , between the flora and fauna of each kind of enviroment, in every different place of every continent. 

Introducing a new living being may alter complete that perfect balance, it could reduce to extinction other species ( which it has already happened several times.), it could affect the food source of other animals, etc.

It's not just a matter of: lets introduce a new specie and let's see what happens.!!

Haven't humans learned form previous consequences of this kind of decision, and still we can't find solutions.

We have several cases in Usa, in the United kingdom of animals that became pests , and so on.

This isn't new for us. 

And second, that statement      "why care so much of trying to save animals from extintion if we can bring them back "

 it's not possible to bring back the same animal, with the exactly same characteristic.  Hointer Pointer said it himself in the previous paragraph (paragraph 5) .

You  may bring back a similar animal but  you never going bring the same animal.   

So that statement is wrong.

My point is that, bringing back to life new animals and set them in our world is a decision that needs imperative to be think more than twice.

“We do not own the Earth. We borrow it from our children”.

“Only after the last tree has been cut down. Only after the last river has been poisoned. Only after the last fish has been caught. Only then will you find that money cannot be eaten."

We should stop destroying what wildlife and natural areas we have. We should try to bring back what species we have destroyed. We should stop making the mess we are leaving for future generations to clean up even worse than it is. To live simply is to live well.

Human have always function on the premise that “we do because we can”; this premise has brought us from out of the trees to where we stand now, debating whether we can/should bring back an animal extinct for over 35,000 years.I would agree that it's a waste, except it’s in the making/creating/inventing useless things that human kind has taken most of its great leaps in technologies/medicine etc.So by all means bring back the Great Mammoth . . . just leave the Raptors from Jurassic Park alone.#DeExtinction

Why?  We have encroached on the existing wildlife population to the point of making them extinct (lions, tigers, bears, elephants etc.)  We continue to kill for animal parts that superstitions hold cure diseases - again, to the point of extinction.  So I ask again - why?  Are we going to bring back Wooly Mammoths to breed and support the ivory tusk merchants now that they have all but wiped out the elephant populations???

Blake Robinson

only a x number of species can live on this planet, hence why theres always extinctions. And what bring back a couple of mammoths into an era of global warming, yeah real smart. let them RIP. The niche in which they inhabited tens, hundreds, or thousands of years ago may not exist anymore or already be filled...it shouldn't be used to resurrect, but to help those ones that are suffering NOW.

We need to help the animals we have already, before they go extinct. Many animals don't have room to survive because of humans right now, we don't have the room to create more environments for the Woolly Mammoths or Tasmanian Tigers. We could consider bringing them back after we fix the problem with our current animals. But if we bring do bring them back think about what we would do. Think of all those people who don't care about them, and would just kill them for fun, then we would have to constantly bring them back. We need to put this Resurrection on hold and fix what we have now, and then maybe bring these things back. I think some of these animals would be helpful to the environment, like the Tasmanian Tigers could help population control with overpopulated animals we have now, that the predators can't handle.

but what we can have after that do you think about it!saving speacies go extinct sound more interessting we're waiting .

Why do people say there is no room to bring them back to? Just de-extinct one or two of each study it and let it go extinct again.

cant believe some of the ignorant comments here, saving live species can not be just solved by throwing money in to the issue, the elephant will never be instinct because there are so many in zoo's and other protected areas, and how many humans die or kill each other is not even relevant here, in any case this is not up for debate some of those species WILL be resurrected , the ONLY controversial species that is already prepared for resurrection is the neanderthal ... all those species could be alive today, we not talking about dinosaurs, witch would be a completely different issue . also most endangered animals DNA is now preserved for exactly that reason, and several species are bought back from the brink like the Hawaiian crow from just a few birds now over 40, or the best example buffalo from last 50 now 100000's 1, most species died out before we where born as no one cared back then to save them, the few species who die out these days where already down to the last few before any human alive now where born

How about we bring back the mammoth while elephants and the other now endangered species go extinct, so that we can bring them back later like we might with the mammoth! I'll wait for a time machine ...

Bringing back extinct animals is the equivalent to introducing invasive species into an environment.

This is just about the stupidest idea I have heard in years. We haven't the graciousness to allow the creatures we already share the planet with to have enough space to exist, and we want to bring back long-gone ones? Can you imagine the "not in my backyard" outcry when scientists start looking for homes for their new herds of mammoths? We won't leave enough old forest for a simple owl, but we have some sort of imaginary frontier where these animals can carve out a permanent place? Ha! This is sheer hubris and too-typical scientific arrogance. Its not enough to just "want to see one." There is a greater morality at play here than how much any one person would like to see a real live Tasmamian tiger. Have you forgotten that we brought back the wolves in Yellowstone so that we could start killing them off again, not 20 years later? 

Oh, yes, I forgot...it would be something for people to "get excited about." Now THERE"S a good reason!

I think people forget that in bringing back an extinct species, we remind people of the power and destruction humans are capable of and why conservation is so important, and people will be excited about conserving the species we have now as we bring back the extinct ones. I would love to see all of these species brought back, especially passenger pigeons, I had no idea they were so amazingly beautiful! And we killed so many of them in such a short amount of time, such a shame.

Forget the mammoth, save the elephant!  Why bring back the mammoth when 25000 elephants are being killed each year for ivory and there isn't enough space for them? Put your money into saving elephants!

Well if we can bring them back,,,,,, then why not....... lot of animals have extincted ...... may be due to natural or man made disaster.... if we can make it up a bit..... then its worth a try....

@wendala Gibson I think we can do both, those killed off by man's activities that can be brought back are just as important as those going extinct now.

@Cher Monroe we could get many things by bringing back extinct species new medicines new ideas beautiful creatures and more. Wouldn't you like to see a mammoth on the Siberian tundra or a group of a few billion passenger pigeon enough to block out the sun fly over your house? You say it is gods territory to resurrect dead creatures not everyone believes in god. I hope they bring back the extinct species.

Gregory Williams
Gregory Williams

@Cher Monroe Two different subjects, if man killed off animals that God created we have a duty to bring them back. We aren't talking about creating new critters. Besides, some Christian beliefs, that we can do whatever we want with the planet or the world is ending soon, cause way more harm than good. Fact not fiction.

@Brigitte Meier pretty sure Chinese and others seeking cures would send the saber toothed cat back to extinction once it realized its teeth were also made of ivory and could be ground up and put in a pill.

Gregory Williams
Gregory Williams

@Tom Trujillo Because many of these species would be brought back into areas of the world where they can be protected. We certainly aren't going to bring back animals into Africa or Asia who both have little regard for their wildlife and in Asia where they would be exploited for "medicinal" purposes. 

Gregory Williams
Gregory Williams

@Todd Benziger No, we are talking about some animals that have been extinct for less than a hundred years in some cases. There impact would make the environments more like they would have been if man hadn't killed them off in the first place.

@Bridget Cameron Wooly mammoth's will be in America, we can keep them safe here. Africa and the other countries have to deal with their own problems, there is little we foreigners with no political power or money can do.

James Rafferty

@Bridget Cameron Yea but how many people are being killed each year ? Is that the only reason you can come up with? There is room bring them back ! If we need more room we can get rid of all the idiots in this beautiful world.

@Billy Burke @Brigitte Meier If a Chinese did so, he must have seen too much hollywood movies and he loved to learn from American or European's expanding style, and went against his ancestor's teaching that we must comform and intergrate to the nature since we are part of them.

@Gregory Williams @Tom Trujillo Notice that "religion takes a back seat to money" does not take place only in China, but all over the world. More than 100 years before, if Westerners did not intrude and destroy their traditional culture, natural economy and humility, they would not learn and introduce western technique, science, and particularly, market economy, to develop the strength of defense to protect themselves from aggression. Thus, Chinese people care about money more and more day after day as the policy goes. Western world gain enough benefits from the nature and left a broken earth to the developing countries now they blame these countries continue to damage it. Well, while China takes most responsibilities of such factories for tiger, Western should also take part of the responsibilities, since they were the teachers.

Gregory Williams

@burnyleaf Cai @Billy Burke @Brigitte Meier Dude, the chinese have factories for tigers and import illegally obtained tiger parts from around the world. If your trying to make a point that the Chinese care about nature or even being humane to animals you are truly mistaken. Taoism may have come from China but religion takes a back seat to money in China.
