Duuhbya touting cellulosic ethanol..again. Remember the switchgrass comment in his SOTU speech? Are most environmentalists much further along in realizing the fatal GHG flaw of guzzling crops and spewing them out the tailpipe?

Sad to say
Not many around here have followed the failing fortunes of fuel farming either.
Once and for all could we give the invisible elephant in the room a paint job? When biomass is guzzled as gas, the carbon sink activity of the soil is rendered null and void. Sugar cane, wood chips, corn, beets, whatever...
No way around it. Biomass that goes up into the atmosphere as GHG from a tail pipe does not go into the ground to build a healthy, carbon sink soil ecosystem.
And because of the late stage of addressing GHG climate disaster, not only curtailing as much GHG emmission as possible is necessary, but as much carbon sink activity as possible must also be restored.
