Where the water will come from 25 years from now?

Mankind will probably be able to go there, but it is quite far in the future - I'd say at least 20 to 25 years away.  Whether or not interest in doing so continues will depend on what is going on right here on earth, and whether we have the will to spend the money on the project.

The water will evaporate so there you go.

War, famine, pestilence, death.  Not in 1000 years, not in 100.  Probably only 20 or so.  Oil, bucko, is the fuel of this civilization, and clean water is getting short as well.  When the power goes off and stays off, water doesn't get pumped.  Do you know the location of the nearest natural source of potable water?  Without water, toilets don't flush, and the cities will be dying of typhoid in just a week.\n\nThose neighbors of yours?  Many parts are edible.

Water (rain, snow, dew, ...) which ends up higher than sea level will flow toward the sea if there is any possible path. Since even a mountainous 'bowl' is likely to have a porous bottom, or to fill enough to find an outlet, there will almost always be a flow to lower levels. \n\nFlowing water is not a neglibible force. It will, over geologic time move, dissolve, pulverize, and remove material. Freeze/thaw cycles contribute more than a bit; the Old Stone Face in new Hampshire in N America has recently fallen (literally) to this. Some of that material will be dropped downstream, filling in an existing channel. Spring floods (in places in which snow and ice accumulate on high ground) will provide an annual increase in this erosion, and if they break over channel banks, will accelerate the deposition process (eg, the Nile floods until the installation of dams to stop them). \n\nOver geologic time, a stream (or river) will fill channels repeatedly and will find new flow paths after doing so. What with dumping material from higher levels, and doing it in channels here and there across the gap between highlands, there will be a gradual acretion of soil in that gap. \n\nEventually, the flowing water, combined on occasion with wind and plant and animal soil processing (earthworms, for instance), there will be a more or less level filiing of the gap between highlands, with water flowing across it on the way to the sea. \n\nThat space, with a history more or less as sketched is a valley. Tehy can be narrow (a kilometer or less) or wide (several hundred kilometes). In fact, they can be so wide that it's not possible for a human to see both highlands between which the water flows at the same time. Valleys can also be very long if the highlands are arranged to permit. Consider the Nile, the Danube, the Volga, the Mississippi, or the Ganges. \n\nIn short, highlands erode, flatten out, and fill in the gaps between them. This can be seen in Britain (whose hills and mountains wer once higher) and in the North American Appalacians (whcih were once very very impressively tall). The N American Rockies, S American Andes, and Asian Himalyas are examples of the early stages in this process. Some millions of years hence, all three of these mountain ranges will be much lower and rounder.

Yeah it's getting very clear it's happening. Now we're going to have to find ways to be more efficient. It won't devour the earth, but it can potentially raise heat and suck in a few cities under water.

Well,  there is a new island forming just south of the big island.  It is about 3000 feet under sea, and is not expected to break the surface of the ocean for another 10,000 years.  I'd say that is pretty fast in geological terms.

You should take a look here to see the formation of the ocean basins: http://www.mos.org/oceans/planet/change.html\nand then the next page, to see one theory on where the water comees from:\nhttp://www.mos.org/oceans/planet/cycle.html\n\nPerhaps a better answer is here:\nhttp://www.madsci.org/posts/archives/oct99/941236464.Es.r.html\n\nFurther discussion on the origins of all the water is given here:\nhttp://www.oceansonline.com/ocean_form.htm\nand under the "Origin of the oceans" title here:\nhttp://www.seafriends.org.nz/oceano/oceans.htm

i think that it will not continue i read what scientist say about this question that due to the global warming the ice in the two poles is melting and that the percentage of the water will increase from 75% to 97%after 30 years from now that is because of pollution there wont be land to live

I heard on the discovery channle not to long ago that if we keep using oil at the pace we are.. we'll run out in about 20-25 years.\n\nThat is if they don't find anymore oil to put wells on
