after millions and millions of years,is human species gonna be extinct?

Possibly.\nEither by the sun dying out, thats billions of years away. Or the glaciers melting, thats possible in a million or two, given our pollution. \nA meteor hit can do it, like dinosaur wipe-out. Probability is one in a billion, but hey we have been around for that long or more.

Extinct species, if not extinct by human activity (shooting them, cutting their forests down, etc.), have extinct for a reason - they did not fit well to the enviournment.\nRecreation of such species may destabilize the delicate balance of nature.\nMoreover, any human interferance with nature, whether trying to do good or bad, can only harm it.\n\nThere are two (1.5) reasons. I think you can start with these, and probably the rest will come to mind after writing this. If not, I believe that other people will have further ideas.\n\nGood luck!

Yes but it will be a long time away. In 6 to 7 billion years, stellar evolution theory predicts our sun will evolve into a red giant  and will probably completely surround the Earth. I don't think I will be around then.

for billions of years yet.  However the earth won't always be here to see it.

Mega fauna, like Woolly Mammoths and Saber tooth Tigers, have no chance of ever re evolving, but there are still giant mammals, on the planet earth. Elephants, giraffes, muskox, lions, tigers and the largest animal ever to inhabit our planet, the blue whale, are still very much around, at least for the time being. It would be fantastic if some of the recently extinct, mega fauna, like the woolly  mammoth, the woolly rhinoceros, the giant cave bear, the giant irish elk and the giant three toed land sloth were still roaming parts of our plant. Could you imagine a saber tooth tiger roaming around the hills surrounding Los Angeles, now that would be cool. Unfortunately the recently extinct species, that have been gone for 12,000 years, have little scientific chance, of ever being reintroduced, with today's scientific technology.  The future is wide open however, and the technology might soon exist to reanimate, many of these incredible species, how great would that be. I would love to see a 8,000 pound, 12 foot tall sloth. I only wish the future would hurry up and get here. The expectation and excitement of such developments, are wildly frustrating.\nGreat Question

Well, I'll tell you my best guess and then in a million years, let me know if I turn out to be right.  I think we're going to be:\n\nBrown.  If we last another million years, we'll eventually all become the same color -- some shade of brown.  "White" and "Black" will refer only to colors and not races.  Even today, the advent of global communication and travel means that racial distinctions are being blurred.\n\nBigger.  First-world countries have higher average height and weight than their developing counterparts.  I suppose that this is a nutritional issue and not a genetic one.  But if we're still around in another million, it would be safe to assume that we've figured out our food production problems.\n\nPeaceful.  Chances are that we'll kill ourselves off before too long, but if we survive, we've beaten our own worst enemy -- ourselves.  This could go either way; peace might come only after death and destruction limit our ability to make war.\n\nAltered*.  This is the wild card, and it's a big one.  We're already on the cusp of genetic engineering already; sooner or later, we'll be able to basically choose what our offspring look like.  Who knows what will become stylish along the way?

Although humans have evolved to have the greatest level of intelligence on earth,  intelligence is not only the preserve of Homo sapiens. Many physical and behavioural characteristics of animals occur among a disparate number of species for example, even though the Thylacine or Tasmanian Tiger was a marsupial it had the physical and behaviour characteristics of a wolf. This is called parallel evolution. The same can be said for intelligence, for example, cephalopod mollusc's such as squid and octopus (the most intelligent invertebrates) and dolphins and whales have both evolved seperately to become highly intelligent within their realm. \nAs for a species being a 'threat' in the race for the most intelligent \nin the future, this is very unlikely as evolututionary processes work on the order of thousands of generations. It is also unlikely that humans will survive long enough for another species to supercede us as mammals as a species generally only live on the order of 1-1.5 million years (we have passed our due date!) say compared to insects that live between 10-15 million years as a species.\nThe biggest threat from an intelligent species is more likely to be extraterrestrial!?

Old age, the Earth will gradually become uninhabitable over a very long period of time until the time comes when the few million people that are left only have legends about how the planet once supported billions.\nNuclear war,  pandemics, possible global warming would be as hiccups along the way.

The earth and human race can be eliminated by various things, both internally and externally. Internaly our earth could lose heat and use up valuable resources due to pollution and over production. Externally comets and meteors could crash into earth. The sun wont blow up for a few more million years so you dont have to worry about that.

Homo Sapiens appeared about 100,000 years ago. Without any scienctific inteference at gene level, I suspect there won't be much difference physically, but they will hopefully be fitter and better fed at the world level, with longer and better lives as diseases are eradicated or controlled.\nHowever, if we look at the advances made since the industrial revolution and the earlier age of enlightenment, we will be talking an amazing and unpredictable future, assuming we don't wipe ourselves out. Compared to the 100,000 years we've been here, we've developed the majority of our current technology over a miniscule 300years and the increase in advanced technology culminating in electronics and computers in reality over the last 50, although obviously based on earlier work. It's a really amzing time we're living in, but hopefully the rest of the world will ultimately benefit from the globalisation of technology in a positive environmental and social way and not as is currently the norm of wanton profligate usage of natural resources of western "developed" societies and the random conflicts of the world's societies as a whole.\nMaybe in the next 10,000 years we'll grow up?

NO.\nCould be end of times for humans but not for Earth.

the industrialized world is going to continue to extract, refine, chop down, pave over, and pollute everything in sight, until most land, water, and species have been destroyed and mankind can no longer survive.\n\nonce people have died off and a few thousand years have gone by, nature will begin to heal from the destruction we have caused, and any species that have survived will be better off.

Considering that 99% of the species the Earth has ever seen are now extinct, speaking in terms of probability, we're probably going to be a pretty short-lived species in the grand scheme of things.

No - Nothing has been destroyed. Just changed in form.\nThe planet will be here for a long time to come.\nThat is if time actuallly exists........\nPeople will adapt to changes, as will lots of animals, trees, insects, plants, fish etc\n\nIs this bothering you - cos your lifespan is 120 years tops?\nFu@k the enviroment, enjoy yourself a bit and stop worrying. Let your kids do all the worrying.

The Earth has probably already peaked as a haven for plants and animals and begun its long descent into oblivion, according to scientists at the University of Washington who have plotted out the future of our planet.\n\nThese are not prophets of doom who have mounted the podium to warn us that we are killing ourselves through bad stewardship. They are scientists who say all good things must come to an end sometime, and at best we've got no more than half a billion years left.\n\nAfter that, the planet will return to its ancient past, inhabited only by bacteria and single-celled organisms, just as it was in its earliest years. But in time even those will vanish as the Earth is reduced to a lifeless chunk of rock, or swallowed entirely by an expanding Sun. \n\n...

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.

Brian is right, but I have to add a smart-ass remark that sun will burn up and go out in a few million years, but by then the humankind will either destroy itself, or find a way to move on to other stars.
