Here is an analysis of the situation of
forests in the world with some data and, above all, charts
of their distribution in the single continents.
The importance of
forests in the conservation of
ecological and environmental equilibrium (biodiversity, air
quality, water regulation, etc.)
is one of the issues that receive great attention in the
policies which regard the world. The last data (2001) from the
FAO reveal
that we have reached by now a worrying negative record: the
pace of the disappearance of the tropical forests,
according to this data, is incredible: 26
hectares lost every minute of every day. As if to say the
equivalent of 37 football pitches.
Let’s see what the causes of the destruction are:
1. Two thirds the green belt disappears to give space to the
raising of livestock and
intensive agriculture.
2. A third disappears as a result of logging for commercial use.
Every year, according to the FAO, forests as large as Portugal and Switzerland put
together are destroyed.
We now know that the less forests there are, the less oxygen is
produced and the more Carbon Dioxide increases, producing the
greenhouse effect.
For this reason, a
movement of the opinion that the green mantle of the Planet
should be protected is becoming more and more active.
It is a movement that involves more and more scientists,
biologists and environmentalists, some national governments,
world organizations, and even some industries active in the
extraction and the transformation of lumber.
There are problems to be resolved, such as the emission quotas
for
carbon dioxide for every single state and the ratification
of the Kyoto Protocol
for the reduction of greenhouse gases in the world.
This was discussed in Marrakech, in Morocco, at the last
conference of states involved in deciding how much
to reduce the
carbon dioxide emissions. It was proposed to replant forests,
avoid
cutting them down to the ground,
extracting lumber (a renewable resource) in
such a way as to be compatible with
ecology and the protection of nature.
The attitude expressed at this first conference would seem to
suggest that
forests will be subject to different policies in the near
future.
The population of the earth needs more and more oxygen to live.
The FAO, in its last report, says that 60 million native people
are directly affected by forest activity and a further one
million
200 thousand people
depend on them economically.
To reverse the path of destruction of the forests, an
important organism called the FSC (Forest Stewardship Council)
was founded in 1993. Its headquarters is in Oaxaca, in Mexico.
To this day, 24 and
a half million forests have been certified by 20 official bodies
in the world.
The certification wants to
say that no plant must be cut needlessly; that a policy of
protection of the world’s wooded patrimony be enacted and that
therefore woodland surfaces increase instead of decreasing.
Such action has been implemented especially in Europe (countries
such as Scandinavia) and in eastern countries: a good 16
and a half million hectares.
In the rest of the world, such as in America, in Asia and in
Africa, logging and burning continues at a heavy rate. In Africa
there unfortunately still exists a massive exploitation of
tropical virgin forests, such as in Cameroon, in
Sierra Leone and in Liberia.
A committee of experts of the UN Security Council has put in
evidence, in a report of December 2000, how the Liberian timber
industry “is involved in illicit activity, and a great deal of
income is employed
to finance activity not included in the budget, among which is
the clandestine purchase of weapons."
Luckily there also
exist cases in which, as in the Amazon region in Brazil, some
intervention programs are
providing extensive environmental education programs to make
people understand how counterproductive it is, for the existence
and survival of the local populations, to continue burning forests in favour of agriculture which in
the long term will be unsustainable.
In recent times, in the areas where this program has been
activated, there has been
a decrease in the
burning of forests.
It is worth, however, to look at the forest coverage in every
region of the planet to better
understand what the situation in the world today is.
