Heck, we can go to mars now. How about the moon? The big news not long ago was about water under the surface of the moon. Our own earth has 70% water. We really need that water under the moon huh?
LOL... yeah.. go ahead.. run down to the ocean and start sucking in seawater.. it'll quench your thirst.
We can desalinate water... but it is at a cost.
There is such a small amount of drinkable water on our planet.
Take a look.
The sphere on the left represents Earth with all of the water removed. The blue sphere to the right shows the approximate volume of all of Earth's water. The tiny blue dot on the far right represents the available fresh water. Another way to think of it is that if we represented the size of Earth with a basketball, all the water on the planet would fit into a ping pong ball and the available fresh water would be smaller than a popcorn kernel. Despite being such a water-rich planet, drinking water is one of our most precious resources.
Even if we wanted to shuttle water to the moon at an outrageous expense of energy and funds.... we can't spare it. Really.
Nuc, the man who invented the Segway is working on a device to convert salt water to drinkable water. Along with several big businesses. I'm confident they'll make a device in the near future that will be affordable. Especially for countries that don't have good water. If I remember right, more people die in other countries from contaminated water than anything else.
The amount of drinkable water really isn't a problem...it's the overpopulation.
Check this site and roll your mouse over India and China and look at the lower left side of the screen for the population count. India is horrible.
IMO Water is a matter of how it is filtered or treated - In some countries there is no shortage of water just rather it is contaminated <-- simply get your shiiit together and start with corruption that siphons off money from public works projects for clean water .
Right Carp. Since contaminated water is such a problem and we have incredible amounts of sea water available, figuring out a conversion system that isn't horribly expensive should be high on human being's list of things we need to succeed at.

Excellent. I'm sure that technology will always be moving forward.
The lack of population control that we exercise as a species is the reason we have to keep expanding outward. Yes, we have a planet right here. Yes, we need to learn how to keep our own planet clean and beautiful and not destroy it. But these are lessons that we learn as we go... It may take ruining this planet for us to learn our lesson. Hopefully not.
I don't have the energy to Google what the inventor of the Segway is working on... but we already have desalination tech. Check the Wikipedia reference...
Large-scale desalination typically uses extremely large amounts of energy as well as specialized, expensive infrastructure, making it very costly compared to the use of fresh water from rivers or groundwater. The large energy reserves of many Middle Eastern countries, along with their relative water scarcity, have led to extensive construction of desalination in this region. By mid-2007, Middle Eastern desalination accounted for close to 75% of total world capacity. The world's largest desalination plant is the Jebel Ali Desalination Plant (Phase 2) in the United Arab Emirates. It is a dual-purpose facility that uses multi-stage flash distillation and is capable of producing 300 million cubic meters of water per year. The largest desalination plant in the United States is the one at Tampa Bay, Florida, which began desalinating 25 million gallons (US Gal.) (95000 m³) of water per day in December 2007. The Tampa Bay plant runs at around 12% the output of the Jebel Ali Desalination Plants. A January 17, 2008, article in the Wall Street Journal states, "World-wide, 13,080 desalination plants produce more than 12 billion gallons of water a day, according to the International Desalination Association."
12 BILLION gallons a day.... and it ain't enough.
Now we can have a discussion about how much it costs to lift 1 pound of weight on the Shuttle... and you can guess that, yes, we need to find water on Mars and the Moon.
All the practical stuff aside, we have to do it because we're human. There'll be a lot of practical application that comes from the technological innovations necessary to do the exploring. It wasn't just Tang that we've gotten from what we've done to this point, after all. The machine I'm using right now to type this is a direct result of space exploration. The fact that I can watch in real time while an earthquake is taking place in Indonesia is a direct result of space exploration. The fact that oil companies can determine where unexamined and unexpected oil deposits are located is a direct result of space exploration. But all of that is much less important than the fact that we have to do it because we have to do it. I'm not really a determinist. The popular stuff that gets published about biologists discovering the gene for this that and the other thing always makes me laugh. But I do think that to be human is to want to go and find out. So we'll go and find out. I'm just disappointed that it'll happen after I'm dead. For the longest time I expected that we'd at least have a moon colony by now. Oh well.
