2. Coffee is a brewed drink prepared
from roasted coffee beans, which are
the seeds of berries from
the Coffea plant. The genus Coffea is
native to tropical Africa,
and Madagascar,
the Comoros, Mauritius and Réunion
in the Indian Ocean.The plant was
exported from Africa to countries
around the world and coffee plants
are now cultivated in over 70
countries, primarily in the equatorial
regions of the Americas, Southeast
Asia, India, and Africa.

3. History of coffee
The earliest credible
evidence of coffee-drinking
or knowledge of the coffee
tree appears in the middle of
the 15th century in the
accounts of Ahmed al-
Ghaffar in Yemen. It was
here in Arabia that coffee
seeds were first roasted and
brewed, in a similar way to
how it is now prepared.
Coffee was used by Sufi
circles to stay awake for
their religious rituals.
4. Ecological effects
Originally, coffee farming was done
in the shade of trees that provided
a habitat for many animals and
insects.Remnant forest trees were
used for this purpose, but many
species have been planted as well.
These include leguminous trees of
the
genera Acacia, Albizia, Cassia, Ery
thrina, Gliricidia, Inga,
and Leucaena, as well as the
nitrogen-fixing non-legume
sheoaks of the genus Casuarina,
and the silky oak Grevillea robusta.
5. Sale and distribution
Coffee ingestion on
average is about a third of
that of tap water in North
America and Europe.
Worldwide, 6.7
million metric tons of
coffee were produced
annually in 1998–2000, and
the forecast is a rise to
seven million metric tons
annually by 2010.
