Biodiversity key to sustainable biofuel according to University of Minn. researcher's findings

This scientific evedence supports the wisdom of producing biofuels such as ethanol from prairie grasses, showing that such a system can be truly sustainable over the long run. -- Jeffrey Goettemoeller
Biodiversity key to sustainable biofuel according to University of Minn. researcher's findings (press release):

"High diversity allows us to produce biofuels with low inputs, and this means that we can get more energy from an acre of land, year after year, with high certainty. Because they are perennials, you can plant prairie grass once and mow it for biomass every fall essentially forever"
