Getting Biofuels Right: The Biofuel vs. Food and the Environment Dilemma
Getting Biofuels Right
The Biofuel vs. Food and the Environment Dilemma
David Tilman, the world's most highly cited environmental scientist, talks about stabilizing greenhouse gas emissions while meeting our food and energy needs.
25 Feb 2008, Oregon State University
G David Tilman is Regents' Professor and McKnight Presidential Chair in Ecology at the University of Minnesota, and Director of the University's Cedar Creek Ecosystem Science Reserve. His research explores how managed and natural ecosystems can meet human needs for food and energy sustainably. Tilman has written five books and published more than 200 peer-reviewed papers; he has been the world's most highly cited environmental scientist for three decades.
In his Food for Thought lecture, David suggests solutions: biofuels can be produced from perennials grown on agriculturally degraded lands without displacing food production or causing loss of biodiversity through habitat destruction. Similarly, biofuels made from waste biomass, manure, corn stover, forest slash, or thinnings offer immediate and sustained advantages and net energy gains.
