Global cost of deforestation? $2 trillion to 5 trillion per year

From the BBC, a Deutsche Bank economist estimates that the annual cost to the World of deforestation is between $2,000,000,000,000 to $5,000,000,000,000.

The global economy is losing more money from the disappearance of forests than through the current banking crisis, according to an EU-commissioned study. It puts the annual cost of forest loss at between $2 trillion and $5 trillion. The figure comes from adding the value of the various services that forests perform, such as providing clean water and absorbing carbon dioxide.
