Bottled Safe Water - Good or Bad?

Like the saying "Beauty is in the eyes of the beholder," local conditions and people's circumstances determine the acceptability of every action taken to quench thirst.

Carrying and transporting drinking water for personal and community use in containers fashioned from animal skins has been an accepted practice forever.

Early canteens for water carried by soldiers were fashioned to resemble historical containers created from animal skins.

The first glass bottles were produced around 1500 B.C. but it was only after 1903, when the automatic bottle blowing machine was invented, that people started carrying their individual water supply in glass bottles.
For a long time, soda drinks and drinking water (containing minerals of many many kinds) was sold in glass bottles in stores where the bottle was recycled.
The Plastic Bottle

It was only in the 1960s that plastic bottles (the PET bottle) became cheap enough to be used for dispensing water and other drinks.
The popularity of water in plastic bottles is so great that each year about 38 billion plastic water bottles end up in US landfills.
The water in these bottles can cost $1.50  or more - water that is available for free from public water foundation or for less than a penny at home.
Are Plastic Bottles Good or Bad?
The correct answer is: It depends!
As safe drinking water is easily and commonly available everywhere in the developed world, buying water in a bottle at 10,000 times what it would cost to get from a tap, may be seen as foolhardy and wasteful by some.
But what if bottled water was the only safe water available for miles around i.e. what if there was an implicit guarantee that tap water would be unsafe? Would the purchase of a bottle of water be then seen as foolhardy or wasteful?
Unfortunately, the former case is the typical case in the developed countries of the world, while the latter situation is the typical situation in developing and underdeveloped nations.
Safe drinking water in plastic bottles, at a cost that the lower class can easily afford, may be just the solution for people in the developing and underdeveloped world, when their tap water is unsafe!

Also, if the switch to water bottles engineered with cornstarch. instead of the PET process, can be quickly deployed worldwide, we will also be reducing the plastic decomposition time from 700 years to about 80 days!

"Water Stress" Has Many Definitions

Just like the saying "Beauty is in the eyes of the beholder", Water Stress has different meanings around the globe. Remedying water-stress is difficult when few can agree on what the term means for all of them.
Water Stressed Areas

A large part of the world is experiencing stress on its water resources. Severely-stressed areas (red in the accompanying map) include Southwestern United States,  northern Mexico, Western and Eastern South America, vast portions of India, Northern China, much of Africa that surrounds the Sahara Desert, southern Africa and Australia (not shown)
Water stress, thus, is a fixture of both developed and developing countries

Water Stress in The Developing World

In Asia and Africa, water stress is defined as lack of water for drinking and sanitation, both basic to human survival and good health.
This stress increases with income disparity for those in lower economic strata as the more affluent can get their water needs satisfied using their economic clout.
But even the affluent in the developing world suffer from water stress. Their stress arises from the ever-increasing water demand from production of goods and services that are the benchmarks defining someone as affluent.

The inability to procure water needed to sustain economic growth and lifestyles is how water stress is defined in affluent countries.
Reducing Global Water Stress
So, it is difficult for all the world to agree on a common definition of water constitutes global water stress. And no globally supported effort can be defined and implemented to cut global water stress.The world's worsening water crisis, continues to further worsen.

Water Demand in 2025

Demand for water is growing most everywhere on Earth. But demand growth is largest in the developing world.


Population Growth
Source-Sustainablescale.org
The population of the developed world is projected to grow at a fraction of the growth in population in the developing world.
Of the 10 billion people projected to reside on Earth by 2050, only about 15% are seen to reside in the developed world.
Both the high growth in developing countries' population and the fact that water consumption increases as living standard increase, fuel growth in water demand in the developing world.

As a percentage, developing country water demand is expected to grow approximately 300% over the growth of demand in the industrialized countries.
