End of deforestation in view? Experts advance new way to size up global forest resources

...e that it's possible to sustain a large commercial harvest and expand "growing stock" at the same time. Says economist Dr. Sedjo: "The USA gained growing stock during 1990 to 2005 while harvesting much round wood and some fuel. China did likewise. On the other hand, Indonesia and Brazil lost much growin...

Engineer ramps up protein production, develops versatile viral spheres
