We need to learn how to protect our natural resources.

The earth is not running out of water. Where do you think it goes, after all?

There is always the same amount of water. It recycles.

The earth isn't running out of anything. It may seem like it, but all water simply goes through the cycle.

There are desalinization projects on the go for ocean water. But if we poison the environment to a point acid rain will not just be a local problem like in the great lakes mining areas.

The earth isn't running out of water, it's running out of DRINKABLE water in places where it's needed. A large part of the problem is population growth in places where water is scarce, Los Angeles and Las Vegas for example. The other reason is climate change. The Gobi desert is expanding and threatening Beijing, small changes in ocean levels are affecting shore lines and river salinity, and aquifers (underground rivers) are drying up. The earth has almost as much water now as it did a million years ago, the problem is where ice forms and where rain falls, that changes. Another problem is that farms, especially near watersheds, are over fertilized and contaminating water supplies for cities. This exaserbates changing rain patterns

The earth will never have a water shortage as long as the oceans prevail. Even if the rivers ran dry, the oceans will provide. Turning salt water into drinkable water for humans, is not a problem. Aruba has one of the most elaborate sea water transformation systems in the world. And, the water tastes great.

The Earth is not running out of water, and if it were, we would no more be able to make enough to matter, than we can change the mythological global warming.

The earth is not running out of water, it is running out of fresh water in the right places. Ans water is used in vary large volumes - one common measure is the acre-foot, the amount needed to flood an acre one foot deep. It is very expensive to make clean water out of dirty or salty water, and it is very expensive move water in the quantities needed.

It's not that the Earth is running out of water (or even "fresh water", or even more exclusively "potable water"). After all, rain is fresh and potable, wherever it falls. The problem is that we are running out of potable water (for humans and animals to drink directly) and fresh water (whether or not potable by humans, but still usable for agriculture, recreation and wildlife and fish habitat) in the AMOUNTS, PLACES and TIMES when and where we would like it. That is, we are draining aquifers, such as the Oglallala Aquifer that waters the entire US Midwest and the aquifers that serve the western states, notably California, and most especially Southern California. When those are drained to levels that make "mining" water there impractical, then we'll have to find other sources ... or move to where the other sources are. Those other sources can be existing lakes and rivers (Canada has no real fresh water shortage, after all, and the Great Lakes should never dry up). They can also include storage of the vast amounts of rainwater that fall on the planet EVERY DAY and run nearly unimpeded to the sea. India, for example, is working on civil engineering projects to capture rainwater that has always been allowed to run off during the monsoon season, so that the water can be conserved and used throughout the year. Desalinization is another option for coastal regions. The water is there; it has always been "there". It's just not always going to be in the same place it has always been, or in the same form.

With enough energy input we can. Desalinization or cleanup by filtration and reverse osmosis. +5

It's clean fresh water that is becoming scarce. Desalinization and reverse osmosis are options. +3

The world cannot run out of water. The problem is that it's not always in the right place at the right time and it's also often polluted. The only reason more countries don't make use of desalination of seawater is the cost. At the point where the need outweighs the cost, that is what will be done.
