Lack of water
(By Hélène, Atharsan, Richard)
Water
has always been a vital resource. But water shortage has henceforth
become a problem of global scale. As 783 million people have no access
to water in the World, more than 3, 4 million die each year from water
or hygienic sanitation causes. Solely in Africa, 345 million people
cannot drink safe water, in Asia and Oceania, it is even worse: 396
million people. Nowadays, fresh Earth’s water only represents 2,53 % of
all the seas and oceans. Nevertheless, contrary to what people might
think, if there is an alarming water crisis, it is not owing to its
scarcity, but to its access. If Israel and Cameroon have the same water
poverty index, Cameroon is in a situation of abundance while Israel is a
semi-arid region. All the difference is made on the way Israel operates
its water.
Nowadays,
2 billion inhabitants survive with less than 5 litres of water each
day, and it is called “water stress”. It is indeed impossible, in these
conditions, to have a good hygiene and to live in opulence.
Fresh water is thus a rare commodity for billions of inhabitants. Even
western megalopolises will be concerned by the lack of water in a few
years.
Besides, the water crisis has staggering impacts on economy and
above all, health. 88% of global cases of diarrhoeal diseases are due
to unsafe water, or inadequate hygiene. As incredible as it may seem,
only 1 single dollar can supply drinking water for a child for a whole
year (in developing countries).
Reasons of the lack of water
What are the different ways of using water
at home? Shower-bath, cooking, dish washing, laundry… But there is
another question: What are the different ways of wasting water?
Continuous open-faucet, leak… We are wasting water, an occidental way of
life, for our comfort and pleasure. For instance an American swimming
pool owner will change the water, exhausting hundreds of liters of
water. Can we forget this mind, in order to keep our children’s heads
“underneath” the water?
Lead
by developed countries, the ranking of domestic water waste is
different from the industrial water waste. Touristic countries have to
face an important issue: a visitor uses 300 liters each day by living in
such places. Indeed, sunny places have to maintain the fields of
mini-golf, the green-spaces, and the swimming pool(s). Otherwise, they
couldn’t fulfill the tourists’ needs. Sociology proved that when
a person is not at home or at a relative’s, he does not care about his
water consumption, or not as much as he does in his own house.
In
any case, one major problem still remains: farmers and countrymen water
use. We can’t blame them for making our vegetables grow faster and in
bigger proportions but
they could of course reduce it by different means. In order to make a
foreign country’s vegetables in your own country you have to recreate
their environment, and their “natural” water consumption which is very
probably high.
The dire consequences
Water is in desperately short supply and the lack of water engenders terrible damage… Since water consumption has increased twice as much as the population growth in the world, during the 21st century, it leads us to question ourselves about the future of our planet as regards the lack of drinking water. Indeed if
a country suffers from lack of water, it won’t feed its population and
won’t develop anymore. The investment in safe drinking water contributes
to the economic growth of a country. Currently 780 million people don’t
have access to clean water. We cannot imagine the dire consequences
that the lack of water may engender. If drinking water runs out, the toll on children will become high and the poor will be hard hit.
On the contrary in developed countries, overconsumption of drinking water will empty aquifers and the price of running water will be increased as well. This
issue has been brought up again and again by environmentalists. All the
more so since climate changes (due to the lack of water) lead to
droughts which will have an impact on agriculture and endanger many species and the wildlife. Several countries are already facing this issue.
Little by little people are becoming aware that the lack
of water may jeopardize life on earth. Yet we must not forget that if
water runs out and that water is about common resources between
countries, it may lead to open wars between them. For instance, Egypt threatens to wage war in these riparian countries, Ethiopia, Rwanda, Tanzania and Uganda. Men have fought for strategic islands or for oil (“black gold”), they shall soon fight for "the blue gold" if each person does not share the resources and does not reduce his water consumption.
The solutions
Despite
what people might think there are still good news! As almost 40 gallons
of water are used when we take a bath instead of 25 gallons maximum for
a 5-minute-shower, let’s take a shower! A simple leaky faucet wastes
100 gallons per day… Just by leaving the water running while we are
brushing our teeth, we can waste up to 5 gallons of water. That is not
much, but if everybody does the same, it becomes quickly 20, 100, 1000
gallons! Rather utilize a dishwasher, which uses 10 to 14 gallons of
water, that our hands, as hand washing can waste 20 gallons!
Waste
of water is not unstoppable: by running the dishwasher only when it is
completely full, buying low-flow faucets, taking showers instead of
baths, watering the lawn less often but more heavily, being careful
about closing the valve after using it, we all are contributing to
the reduction of ecological footprint, and thus of the lack of water…
If we really want to stop the damage caused by the human kind, we all
have to make some efforts. Actually, there are many ways to reduce our
water use. For instance, if someone prefers taking a bath at the end of
the week after an exhausting day, it is not really catastrophic if on
the other hand he waters his lawn just once a month and buys a low-flow
faucet!
To
conclude: at last but not least, the experts estimate that in 2025, 17
other countries, including Ethiopia, India, Kenya, Nigeria and Peru will
be added to the list of countries in lack of water. China and Pakistan
will approach the state of water stress. Water
shortage has become such a priority that the number of wars to obtain
it has considerably increased since the beginning of the water crisis.
However, there are solutions we should not forget, by making efforts on
your own and warning your relatives of the danger of water shortage, you
are taking part in the fight against the lack of water !

Water Pollution
(Samson, Alexandre, Ilies & Thomas)
Water
is as necessary as deadly. Preserving life, water is everything for
our system. It is the resolution of the complex equation of
Humanity. What does it really mean?
But
for centuries people have never stopped taking this resource for their own interests,
breaking the by dumping waste into the sea or oil spills. Human influence
has had a devastating environmental impact and has turned water into
a dangerous resource, as a deadly liquid « drinking water » is now as scarce as
gold.
However,
this
pollution doesn't come from nowhere, what are its causes and
consequences? What are the solutions? Is drinking water still available
in a World
supporting seven billions humans?
Questions requiring
answers...
Nowadays,
a lot of our daily actions and practises are harmful for our sources
of water.
Firstly,
the principal factor of water pollution is urbanization. Indeed, the
increasing of water supplies and its treatments are partly
responsible for this pollution since towns and cities aren't ready
yet to practise waste water treatment resolutions. Therefore it is
one of the main causes of water pollution.
The
industries are also involved in water pollution by producing
industrial wastes which pollute rivers and sources of fresh water.
However
the most polluting sector is agriculture. The main cause of water
pollution is the use of pesticides and fertilizers. These improper
agricultural practices pollute waters and make them totally unsafe to
drink.
Surprising
though it may seem, religious practices are also harmful for
waterways. Sacrifices are sometimes done in rivers and body ashes are
flung into the rivers. Mass baths during religious feasts like in the
Ganges for the Hindus is also a polluting practice. Moreover, water
pollution can also be caused by natural facts like animal's droppings
or acid rain caused by gases which dissolved in rainwater.
Eutrophication
is also a cause of water pollution. It is caused by agriculture and
is the natural nutrient enrichment of streams and lakes. It causes a
growth of algae which amplify the growth of bacteria.
Yet,
one of the most important causes of water pollution is the lack of
awareness of humans. That's why environmentalists are spreading their
ideologies to reduce the humanity ecological footprint on water.
The
consequences of dirty water are numerous and disastrous.
Today, almost 2
billion
people cannot drink or use clean water just because of its
pollution. Indeed, drinking unclean water has terrible consequences
on health, like vomiting, diarrhoeal, cancer,
reproductive and developmental problems. Children are the major
victims of this pollution: 6,000
of them die
every day because of diarrhoeal
diseases. The poorest countries are evidently the most stricken.
But the fauna and flora are also threatened by water pollution. Many
species like coral reefs
could disappear if they aren’t protected. Oil spills accentuate
this phenomenon: in 1989, an enormous pool of oil (which had the size
of 125 Olympic swimming pools) killed
250000 shorebirds, 28000
sea otter and 300 seals.
Almost
the half of the rivers are polluted
in the world. The Ganges is a good example to illustrate the gravity of the situation. Indeed,
it is one of the most polluted in the world, because of industry but
also because of the bad influence of local populations.
A lot of dangerous chemical products are rejected in this river, like chromium or arsenic, and it flows
400000 litres of sewage every day. But the Indian
government doesn't react, concentrating on economical development in
spite of the environment.
Another
example is The Pacific Trash
Vortex,
also known as The Great Pacific Garbage
Patch which has been discovered by the
skipper and oceanographer Charles J. Moore in 1997. This Vortex
consists in an enormous area of detritus. The size of this island is
estimated between
700000 square kilometers to 2 million square kilometers. 267 species are affected
by this “8th continent”.
Water pollution becomes one of the major issues for
almost all the governments of the world and especially in the Third World. That’s why more and
more initiatives are taken in order to control and reduce it.
One
of the most effective way to reduce our
ecological footprint on water is therefore to prevent its pollution,
by not littering in the sink or even in the toilet, as well as in
rivers, lakes or seas, by using pesticides, fertilizers and toxic
household products as less as possible or even by having more plants
in our garden for preventing polluted water to run off into water
sources.
The
law aims at avoiding useless
water pollutions as well. In Europe, for example, dumping of nuclear
waste is forbidden since 1986, one of industrial waste since 1989 in
North-Western countries. Yet the fight for water quality protection
is also and mostly led by agencies and organisations like Greenpeace,
WWF, Wetlands International and Marine Conservation Society.
The
main mean to reduce water pollution is still the water
treatment plants construction,
which makes us remove solid
particles, inorganic, organic and chemical waste, mostly by the use
of filters.
Nevertheless
other ways are intended for water pollution reducing as septic tanks
which let us treat sewage locally. One
of the water treatment plants which is
being more and more used is yet less known: the Ozone
waste water
treatment. It uses a generator which transforms oxygen into ozone;
ozone then oxidizes bacteria and all types of waste present in the
water and destroys it.
Even
though all those means are very efficient, they wouldn’t be useful without the
rise of an environmental consciousness. That’s why today the
principal way of protecting water quality is to spread ecological
ideas and living practices.
We
saw
the impacts and consequences that unclean or polluted water could
have on Earth and society. Killing people every day, or just
unavailable in parts of the World, water has become a geopolitical
issue. Trying to preserve the future, green agencies or environmental
organisations have sprouted
all around the planet in order to suggest solutions in a World which
doesn't want to change its way of life and overconsumption problems.
Yet, in the meantime, flora and fauna gradually disappear. Time
passes and solutions are still missing (even if few solutions are easy
to find) for a World whose population will reach a nine billion limit in
2050 with inefficient accessibility to
water.

Perfect World
Land of prosperity, filled with adventurers
Witness of History, You've lived all the ages
Harvest of the angels, symbol of all wonders
You were the fire and the light on their faces
Seas of brotherhood, you made the last sacrifice
Seas of humanity, of our spirit you're made
Seas of simple beauty and balance of my life
I cry for you today, can you just feel my pain?
You've been lured, you've been raped, losing your purity
And while Human beings are giving up their respect
For the human downfall, forever I'll feel guilty
My old friend, can you hear the sound of the waves?
From dark shallows only shrills the echo of treason
It is the conquest of sea by human pollution.
