If you thought burning food for fuel — agrofuels — has been an unmitigated disaster, just wait until we start chopping up our last natural forest habitats for cellulosic ethanol biofuel. Much heralded second generation biofuels, to be based largely upon woody biomass, will be a resounding ecological disaster, and must be stopped now. It is a myth that enough unused forest and agricultural waste, and a surplus of land to grow various grasses and wood, exists to base an industrial energy source.
Humanity must stop seeking easy answers to perceived energy shortages that in fact are a result of over-population and ecological limits to growth. Agrofuels were heavily promoted for climate benefits and pursued at much expense, yet have been catastrophic to the world’s food security, habitat, water and climate. The same will be true of ethanol production from trees. Cellulosic ethanol will be the ultimate deforestation biofuel, equivalent to dismantling and burning your home to keep warm.
The promise being made is that wood can produce fuels to run our cars. A few years ago we were told corn, rapeseed, sugar, oil palm, soy and various other crops could be grown for biofuels while providing energy security and reducing greenhouse emissions. The reality has been far different with globally surging food prices, loss of rainforests and other important habitats, further depletion and poisoning of aquifers, and rampant human rights abuses — all for little or no greenhouse gas emission reduction.
So called “second generation biofuels”, including the use of woody biomass, is being given the same unthinking, ecologically bereft hype. I will focus upon the idea that a wide variety of woody plant materials — including both waste and planted woody crops — should be the basis of a cellulosic ethanol industry. Creating ethanol is trickier than with agrofuels, the cellulose more difficult to break down, but clearly it is possible to produce liquid fuels from woody biomass. But what of associated social and ecological issues that are again being ignored?
Second generation biofuels based upon woody biomass will clearly be an unmitigated disaster. As with agrofuels, a cellulosic ethanol industry will indirectly destroy forests and lead to more costly food by increasing land pressures upon natural forests and agricultural crop lands. We can expect more vast, lifeless, toxic and water dependent monocultures of genetically modified Frankentrees on stolen deforested lands at a net carbon loss. And the biofuels will be sold to us as a green product, perhaps certified as “well-managed” by WWF, FSC, and other forest sell-outs.
Forest waste is a euphemism for the materials left over when industrial forestry decimates a forest. The branches, bark, saw dust, etc. represent nutrients that are best returned to virtually mined soils to make new forests. There is certainly not enough such “waste” lying around unused to power industrial society. Just what the world’s beleaguered natural old-growth and regenerating forest ecosystems need, another potentially limitless draw upon their growth, diversity and regeneration.
