Consider the environment before printing...? Really?

We've all seen the email signature asking you to think before you print. The intention is admirable, but how relevant is it? 

Did you know that paper produced for printing is derived from trees that are farmed specifically for producing paper. And the interesting part about this is that the paper industry actually plants more trees than it harvests.  Today there are more trees in the developed world than in 1900.

This makes the paper industry more sustainable than many. 

A gent by the name of Harry Brelsford wrote an alternative email signature to bring some light to this info;

"The paper industry plants more than it harvests and today there are 25% more trees in the developed world than in 1900. Paper is biodegradable, renewable and sustainable. Growing and harvesting trees provides jobs while forestry plantations provide clean air, clean water, wildlife habitat and carbon storage. A decline in the demand for paper products risks a decline in sustainably managed re-growth forests."
