2.  Deforestation is the process by
which trees and foresets
desappear, basically caused by
human activity.
 Deforestation is mainly caused by
men due to the cutting down of
wooden factories, as well as for
getting ground to seed plants.

3.  MAIN CAUSES OF DEFORESTATION
The main cause of deforestation is the growth of population.
The next increase about the demand of wooden products of forest
land.
the search of new lands for growing in developing countries is the
cause of cutting down forests.
Ranchers cut down thousands of hectares of rain-forest in order
to the animals eat along the year, moving once the food is sold out.
To the aim of satisfying the increading demand of wood, furniture
and paper, the developing countries have turned to the high
reserves of humid forests.
For the population, every time more populated in Africa and Asia,
wood keep being the basic combustible to elaborate food and for
using it with the heating.

4.  Direct consecuences of Deforestation are different,
concerning every kind of species and habitats and
provoking an important ecological unbalance.
 One of theses consequences is the extinction of
carbon dioxide drains, reducing the capacity of the
environment of being capable of absorb this CO2
for change it into oxygen and in that way, carry out
the greenhouse effect.
 Besides, with so much cutting down and
indiscriminate burning, it´s produced an important
change in the grounds that some time after, it will
change the weather, because it will have not so
many protection and retention of humidity, causing
droughts in this way.

5. -One solution is the prevention, that carries out plans like
education, but forestal education to become aware in young people
that it´s a natural resource that taking care of it has a lot of
economic potential.
- To preserve forests and use them racionally, avoid destroying the
most valuable species and letting they restore with their own seeds.
- To supply firewood and other forestal products, we must seed
trees of fast growing that are be able to take profit of them in little
- As a way of retaining wall, different international organisms
propose Reforestation, a parcial way accepted by the ecologist
movements, because they say in the repopulation we must take into
account not only the elimination of Carbon Dioxide, but the
biodiversity of the place to replant as well.

6.  - To elaborate products that come from wood
(paper, pencils, etc) or other products more
valuable, like furniture.
- To produce pure oxigen of trees and
reabsorv carbon dioxide for this question. This
generates a kind of change for external debt to
highly developed countries that pollutes. It´s
got a name: KYOTO CONVENTION.
- Another way of solve this important problem
of deforestation would be the agroforestal
systems, that are the ones that in which some
species of trees are kept.
