The most recent detailed worldwide assessments date from 1990. At that time deforestation was 150,000km per year or 37 million acres.
More recent, though not as detailed reports, suggest that in 2005 there were 32 million acres of forest lost but at the same time 14 million acres of new forest were planted - a net loss of 18 million acres.

i dont know that
trees are coming down all the time ,
in My town trucks loaded with huge logs of exotic timber leave the mountains with permits bought from corrupt oficials almost nightly
we can only guess at the exatct amount but from my house we can see many bare patches on the mountains and the river is constantly muddy in the last 3 years ,because topsoils, without the protection of the forrests , is washed into the rivers ,
this is just one place and this is happening all over mexico ,the Market for the wood being the USA.
here is a general note on deforestation
CAN DEFORESTATION BE STOPPED
Almost impossible
the Indians or local people would cut everything down and burn the forrest to replace it with harmfull short term farming killing the soil in no time
expanding populations and expanding farming ,that has to keep pace with the expanding populations are very strong forces that encroach upon the rainforest's
clearing them for farming and settlement areas .
that and the giant networks of roads that have exchanged forests for asphalt all over the planet
In Mexico is a famous jungle that the Media has been trying to save for years
the Naturists ,and the government ,keep watch .laws are made for protection the wild and to forbid logging.
TV put out a series of documentaries
there are campaigns in the News papers
and all of this has not made the slightest difference
Rainforest's always are in third world countries and always in third world countries corruption and the need for money s highest
the jungle gets smaller by the day
more and more farmers move in .and burn the trees
it is an impossible situation
as long as there is poverty and an increasing birth rate in these regions the destruction will continue
they are too easily tempted to sell of exotic animals to the unscroupelous people who buy them.for the market that exists in the USA.
we must look for ways to improve economic situations on the edges of Nature .
the only way to preserve the forrest is to devellop eco tourism under strict control that has limited acces ,and use the local people in the concept as guides ,hotel staff and get them to start home industries of artifacts .
eco tourism is the only concept that profits by a healthy back ground with out harming it
REFORRESTATION
we must reforrest and at the same time reduce our carbon emissions.
most governments are aware of these and many first world countries now include programs to reduce their carbon emissions.
the world bank pays large subsidies for farmers to plant trees especially a tree called Paulownia elongate carolinia,because it is one of the better ones that capture carbon.
IN THE PAST
the sahara used to be forrests
arabia ,irak ,iran used to be fertile lands in biblical times
Ghengas Kahn burned all the forrests here and filled the well with water and so turning vast lands into dessert.
the Spanish Armada deforested Spain
.the Phoenician fleet deforested Lebanon
Madagascar a botanic paradise is now destroyed
the exotic animals sold or killed ,the forest slash and burned for agriculture ,the coastal water poluted by topsoils washed fronm the denuded moutains by the rains.
many many countries in Africa (because of poverty and war as well as greedy farming )
Borneo because of the expensive timber
india ,China ,Mexico ,South Americas Amazonia,
Europe because of civilization,USA,Japan because of overpopulation,
read a planet under stress ,plan B --by Lester E Brown.
it is in an Adobe print out as well on the net.
