Reversing the spread of hunger is one of
humanity’s paramount challenges. It will mean overcoming
the fatalistic belief that chronic, persistent hunger is
inevitable. It will mean reversing the trend toward ever
greater concentration of wealth in ever-fewer hands. It
will mean building our lives upon the certainty that all
humanity is connected.

| When humanity finally sheds the
onerous and degrading spectre of starvation, it will be because
we have decided not to treat food, and the resources needed
to produce it, just like any other commodity, but have come
to see food as a basic and universal human right. It will
be because we have found ways to stabilize our numbers and
to heal the planet’s deeply injured life-support systems.
It will be because we have realized that only when none of
us fears hunger can any of us truly find peace.
And it will be because we have returned
to the efficiency of a plant-based diet, making it possible
for more people to eat. It is increasingly obvious that
environmentally sustainable solutions to world hunger
can only emerge as people eat more plant foods and fewer
animal products. To me it is deeply moving that the same
food choices that give us the best chance to eliminate
world hunger are also those that take the least toll
on the environment, contribute the most to our long-term
health, are the safest, and are also far and away the
most compassionate toward our fellow creatures.
Reversing the spread of hunger will mean
learning to create a world based on cooperation and on
the affirmation of the human spirit. It will mean organizing
our societies in ways that assure every person the chance
to live a healthy and productive life in harmony with
Nature. It will mean examining all of our public policies
and personal lifestyles in the light of our desire to
touch as many people as possible with a message of hope
for a better world.
“The day that hunger is eradicated
from the Earth there will be the greatest spiritual
explosion the world has ever known. Humanity cannot
imagine the joy that will burst into the world on the
day of that great revolution.” (Frederico Garcia
Lorca)

Aquaculture
Aquaculture is the practice of avoiding
going to sea by raising fish in ponds, it was one of
the most ancient of human preoccupations and we’re
still not very good at it. Technically, you can do
just about anything, but it’s not necessarily
wise that you should.

Modern aqua cultural practise
is not the solution to world hunger, aquaculture in its
present form produces for those that demand and are willing
to pay the price.
Is Ocean Aquaculture
or Marine Horticulture Sustainable?
As many fish are harvested for fish
meal as are created by aquaculture. Open Ocean Aquaculture
is seen by many as a way that aquaculture could safely
and economically expand. Seeing a limited supply of
coastal waters which are not yet ruined, focus is now
on utilizing the open ocean area, and developing submerged
and partially-submerged galvanized pens capable of
sustaining the more unpredictable and harsh conditions
5km or more off-shore. Risk of contamination by chemical
and biological agents is greater in freshwater and
coastal ecosystems than in open seas; stationed in
deep water with strong currents, it is hoped that the
ocean farm's wastes and other pollutants are unable
to reach noticeably harmful concentrations. The sturdy
cages are thought to be relatively escape-proof, reducing
the chances of infecting and destroying wild populations.
Furthermore, the cages are tended and monitored by
automated feed buoys, so they appear to be cost-effective
not requiring the employment of any (or many) people
from the local population.. It is hoped that research
may lead to widespread use of an allegedly environmentally,
economically and socially “preferred” aquaculture
system by 2012.
So what is sustainable
Aquaculture?
Simple, traditional, sustainable aquaculture is that
aquaculture which can be achieved without substantial
inputs of energy, feeds and utilizing low density stocking
rates of fish and without major environmental manipulations.
Primary feeds are naturally produced. Major inputs are
labour usually from the farmers family. Operations are
characterized by intensive husbandry , low overal capital
expenditures and continued production over a long period
of time . Due to lower stocking levels the health of
the fish is generally much hardier than with higher stocking
levels due to less stress and less exposure to disease
pathogens. Operating equipment is usually low powered
aerators and/or recirculating pumps, if any.

This system is often used for rural pond
production without any operating equipment, ponds are stocked
with either single sex populations or mass harvested after
a rearing time of six to eight months of grow out time
and the entire crop sold.
In the most basic mode ponds are stocked and fish naturally
produced are harvested by angling or netting. This is
the lowest production mode, and when fish are produced
without a predator to remove most of the natural fry
produced the ponds will soon become over populated and
the bulk of the fish will be stunted in size. Stocking
ponds with all males is the simplest production method
to produce a marketable crop. The fish can be harvested
over a period of time allowing the fish to continue growing.
To this model, various techniques can be added to increase
production: feeding of natural feeds, such as duckweed
and greenwater.

Adding fertilizers such as manures to produce
phytoplankton. Growing plants that will reduce nitrates
in the water (nitrates reduce fish growth rates) such as
water hyacinths, water lettuce, best of all growing edible
plants and herbs fed by a solar/wind powered pumping system
for damp ground or paddy fields for wet ground or on floating
rafts on water like a lake. All is food that can be harvested
for human use.
So where and when
do the lights get switched on? Photoperiod Manipulation
All animals and plants can be manipulated this way,
this is one reason why the Sun on Earth is so important.
Fish reach maximum weight following maturation by which
time the texture of meat can be unpleasant and distasteful.
Using artificial daylight such as sulphur plasma lighting
to manipulate the photoperiod (Daylight intensity and
duration) means that farmed fish have accelerated growth
levels and can gain much weight before maturation ensuring
the harvested meat is plentiful and well edible.
