Participants at the latest meeting of the U.N. Environment Programme’s Convention on Biological Diversity expressed growing concern over the increased use of non-food crops as sources of cellulosic ethanol. According to The New York Times , scientists from organizations such as the Nature Conservancy, The International Union for Conservation of Nature, and others concerned about the use of plants such as reeds and wild grasses may clash with policymakers in the U.S. and E.U., both of which have established targets for expanding biofuel use in response to climate concerns, and are now “anxiously awaiting the commercial perfection of second generation biofuels.”
The scientists’ concern stems from the fact that many of the plant species targeted for use as “second generation” biofuel sources (i.e. non-food crop sources of biofuel, as opposed to corn or soybeans) are not native to the areas in which they will be harvested as a fuel source, creating risky potential for their spread as damaging weeds. They cite biodiversity loss and economic costs as possible side effects of culitvating invasive species for fuel. Continue reading ‘More bad news for biofuels? Well, that depends…’
