If potable water scarcity is not on your survival list yet, have no worries, it is most likely to appear rather soon. Here are several facts that might convince you in a more appropriate manner:
- 70% of worldwide ocean are glaciers.
- 20% of the remained part are the areas too remote for humans to access.
- 3/4 of the 80% of above mentioned remained part are monsoons and floods that usually cannot be captured by people for treatment.
- What’s left? Miserable 0.08% of a single percent to quench the daily thirst of a whole human race.
Considering that we were approximately 2.5 billion in 1950s and outreached 6.5 billion by 2008, water scarcity is no longer a myth. In other words, if today we are blindly fighting for energy sources, tomorrow we will consciously fight for water. But hopefully scientists are struggling to prevent such a sad scenario. There are already existing solutions based on nano technologies that have ability to efficiently purify water. Here is the impressive video for better understanding:
If nano technologies become affordable to all social levels, such water-purifying solutions can be installed in every household. That would definitely solve the problem of a potable water, but certainly not the scarcity. In theory, as I see it, this second part of the problem requires nothing but a built-in water reservoir and a closed water circuit per each particular household. Thus, all consumed and contaminated water can be instantly purified and refilled into the reservoir for recurring use. The waste products arising from the purification process can be stored in a special compartment for further recycling. This might surely require extra expense, but considering that such a solution would significantly save your water-related expenditures and commit no harm to environment, it is a dime deal.
Anything to add? Or does anything similar already exist?
