Our own history here in the UK has
been one of deforestation.
This happened over thousands of years
and our forest area reached an all time
low at the beginning of the last century.
At that point, woodland cover
in the UK was just 5 percent.
We have rebuilt some
of our forest resources.
In the last 50 years the UK's
forest area has more than doubled.
Similar patterns of deforestation followed by
reforestation took place in many other industrialised nations,
to the extent that forests in
these countries are now
reabsorbing carbon dioxide again.
The forest area in Europe grew
by 13 million hectares between 1990 and 2005.
That's an area roughly
equivalent to the size of Greece.
But globally the forest area
is falling, and at an alarming rate.
Remember that 13 million hectare increase
in Europe that took 15 years to achieve?
Global deforestation accounts
for around the same amount every year.
Tropical countries are most vulnerable.
South America suffered the
largest net loss of forests from 2000 to 2005.
About 4.3 million hectares every year.
This was followed by Africa,
which lost 4 million hectares a year.
