coming from around the world that by tagging ethanol as green, and increasing our demand for "green energy," we've been doing damage to the environment rather than saving it. I'll leave evaluation of these claims to someone else for now. However, I'm interested in whether discovering a thermodynamically efficient process for generating cellulosic ethanol might cause more environmental harm than it prevents. Some reflection on the issue suggests that the potential for damages (in the form of habitat, biodiversity and ecological stability losses) are far greater than anything we have observed yet with standard ethanol. In fact, since it seems unlikely that we will be able to tightly control the use of whatever cellulose-to-fuel technology we invent, perhaps we actually have a responsibility to stop research in this field,...
