Food of the Gods
The cacao tree is an illustrious
native of the Americas whose fame has been sustained
by the massive consumption of a product much desired
around the world: chocolate. But many people are unaware
that this delicious food originates from a tropical
tree, producer of an extraordinary fruit.
In the mid-18th century, this
fruit received a formal name from botanists, 'Theobroma
cacao'. The first part of the name insinuates
a relation dating back to ancient times, that of "food
of the Gods."
The main consumers of cacao in
antiquity were the Meso-American peoples. The Olmecas,
Mayans and Aztecs were well aware of the secrets possessed
by this fruit, or bean. They used it as currency and
consumed it as a beverage, known as 'xocolatl', the
world that gave rise to the English word "chocolate".
For the Europeans it was at first
a curiosity, and then a highly prized product, sought
by the first merchants in the New World and demanded
by the elite classes on the European continent. It
was there that cacao, or cocoa, was first mixed with
milk, and where the first chocolate bars were produced.
The cacao tree
grows in areas of dense vegetation. The fruits, which
can be of extraordinary colors, grow on branches and
hold the seeds covered by a white and refreshing pulp.
In the process of turning cacao into chocolate, the
seeds are dried, toasted and crushed.
The Internet
holds a vast array of information about cacao, ranging
from its role in the world
market to its history and its amazing transformation
into delicious chocolate.

Air in Motion
The wind blows continuously
in every corner of the globe, showing its different
faces: from barely perceptible breezes to mighty hurricanes.
In every case, however, we are talking about the same
phenomenon, which has one single definition: "air
in motion."
Despite the ubiquity of the wind in the lives of human
beings, it is not easy to find information describing
it on the Internet. Many searches end up at sites
dedicated to its use as a source of energy, or referring
to the use of the word in a figurative sense: it refers
to something passing, ephemeral, something that never
stops or that can swell to stormy levels.
The sites that describe wind go a bit deeper. The
sun has to do with the origin of the wind, which is
produced by the uneven heating of the earth's surface,
which in turn generates areas of high and low pressure.
The differences trigger movement in the air mass.
There are a number of kinds of wind classified by
scientists, and tools like the Beaufort
scale have been designed to gauge intensity, starting
with a light breeze and running all the way up to
devastating hurricane-force winds.
The speed of wind is measured with the help of an
anemometer.
This can be a sophisticated apparatus, or simple homemade
instruments. The information gathered is an important
input for the producers of wind power, a clean, abundant
source of energy.
Wind has an enormous influence on life. In nature,
one of its key functions is as a vehicle for pollination.
In the case of human beings, it propels boats and
windmills, and even feeds our imagination.

Food Insecurity
Hunger is one of the worst miseries,
and in spite of all the technological and social advances
that humanity has achieved, more than 800 million
people on the planet suffer its effects today.
In slightly more technical terms,
it is a matter of "food insecurity". It
is when people go hungry and fear dying of starvation,
according to a definition posted on the website of
the United Nations Food and Agriculture Organization,
better known as the FAO.
The FAO has convened a World
Food Summit for June 2002 in which the main focus
will be the need to intensify the fight against hunger
worldwide.
The delegates are to make an
assessment of what has been achieved since the previous
summit, in 1996.
On that occasion the Rome
Declaration was signed, a commitment to cut the
impact of world hunger in half by the year 2015. But
little progress has been made so far, and it will
be difficult to meet that goal.
One of the objectives of this
year's summit is to strengthen the political will
of the world's governments to fight hunger.
The Internet holds abundant
information on the issue, ranging from World
Food Program news about food emergencies to proposals
for political action suggested by activists and organizations
with a presence on the web.
