From BBC; deserves far larger headlines than it will receive, as ramifications of forest losses so immense:
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.
The study, headed by a Deutsche Bank economist, parallels the Stern Review into the economics of climate change.
Speaking to BBC News on the fringes of the congress, study leader Pavan Sukhdev emphasised that the cost of natural decline dwarfs losses on the financial markets.
"It's not only greater but it's also continuous, it's been happening every year, year after year," he told BBC News.

"So whereas Wall Street by various calculations has to date lost, within the financial sector, $1-$1.5 trillion, the reality is that at today's rate we are losing natural capital at least between $2-$5 trillion every year."
The review that Mr Sukhdev leads, The Economics of Ecosystems and Biodiversity (Teeb), was initiated by Germany under its recent EU presidency, with the European Commission providing funding.
Key to understanding his conclusions is that as forests decline, nature stops providing services which it used to provide essentially for free.
So the human economy either has to provide them instead, perhaps through building reservoirs, building facilities to sequester carbon dioxide, or farming foods that were once naturally available.
Or we have to do without them; either way, there is a financial cost.
