5. • In 20 years, the world’s two most populated
countries, China and India, are expected to exceed
their supply of water.
• In an estimated 25 years, the human race will no
longer have enough water to survive on.
• The fear of not having freshwater can already
been seen in countries like Pakistan, the demand
and control of water being a contributing factor to
the unrest in the region.
• In the United States, places like
Georgia, Florida, and Alabama, states with shared
rivers and water resources, have engaged in legal
battles over who has the right these supplies.
6. • As the worldwide population continues to
increase, so does the need for water to be used in
growing crops, a task becoming harder in the
developing areas of Africa and South America.
• In developed nations, the destruction of
underground aquifers from construction and
expansion increases the loss of water available.
• As the world becomes more industrial water
pollution decreases and destroys a supply that
would otherwise have been useable.
• As a result of this depletion in freshwater, the
world could one day see a war that is fought over
water and the right to use and control it.
8. Decrease Water Usage
• The first step to this solution would be to increase
in public awareness.
• Giving this issue as much attention as global
climate change may lead to a person being just as
likely to take a quicker shower as they are to toss
a plastic bottle into the recycling bin.
• New technologies such as the EPA supported
WaterSense or the water-efficient Energy Star
offer appliances that reduce the water used
without sacrificing ability.
9. Desalination of Seawater
• The undrinkable saline waters of the world’s oceans make
up 97.5% of the water available on planet Earth.
• Through the process called desalination, salt water can
become a safe, unlimited water supply that can be used for
domestic, municipal, and agricultural purposes.
• Desalination can be accomplished through several different
techniques, such as thermal distillation, which mimics the
Earth’s natural water cycle utilizing evaporation and
condensation, or membrane and filtration, a process that
basically strains certain ions and minerals from the water.
• Similar methods can be applied to other sources of water
that would be otherwise unsuitable to drink.
10. Reform Agricultural Methods
• Make changes to irrigation techniques can be made to
make the current water use more effective.
• Repairs and improvements to already existing canals
can be made so the amount of water reaching farm
lands can increase while simultaneously decreasing
what is lost in the process.
• Advancements in the crops themselves, using science to
engineer crops that can withstand in periods of
drought, requiring less water while still growing to
successfully serve as a food source.
