With Climate Change concerns heating up substantially, researchers point to concrete solutions in the Ag biomass sector. Corn based generation of ethanol has serious drawbacks and does not nearly contribute to the mitigation of climate change.  With second generation ethanol production, based on tall grasses, we can make a substantial contribution by reducing CO2 emissions. 

The article in EcoWatch looks at the benefits of perennial tall grasses, like switchgrass and miscanthus.
