"It's not food, it's not fuel, it's China," said Jim Lane, editor of Biofuels Digest and author of the report.
The study determined that China's meat consumption since 1995 has increased by 112 percent to 53 kilograms per person per year.
"If the Chinese people had consumed the same amount of meat, per person, in 2007 as in 1995, there would have been enough grain left over to support 927 million people with food for an entire year," said Lane.
The study found that the U.S. increased corn production by 157 million tonnes of corn since 1995. 31 million net tonnes of grain went to support U.S. ethanol production, and 27 million tonnes supported a 15 percent increase in U.S. population during the period. By contrast, the study projected that livestock grain demand to supply Chinese meat consumption increased by 199 million tonnes between 1995 and 2007.
"Given that the U.S. population grew 15 percent, the 82 percent increase in U.S. corn production left plenty for
people, plenty for livestock, and plenty for ethanol," said Lane. "The bad news is that we have a global fuel and food crisis of the first magnitude. The only good news is that it's easier to find a steak in Beijing."
The study tracks the meteoric growth in Chinese meat consumption since 1983, a trend spotted early by commentator Lester Brown in his prescient article "Who Will Feed China?" In 1995, meat consumption was 25 kilograms per person, reaching 31 kilograms by 1999, 50 kilograms by 2000, and is 53 kilograms per person today.
"Chinese meat consumption is still 45 percent less than the average consumption in the U.S.," Lane warned. "An
additional 277 million tonnes of grain would be needed to support China at parity with the U.S. That would take 68
million acres to grow. There isn't that kind of arable land available anywhere is the world, whether we use grains for renewable energy or not."

Bioenergy from Microscopic Organisms
Oak Ridge National Laboratory microbiologist Tommy Phelps sees the untapped potential of bioenergy in shelves of bottles and beakers containing microscopic organisms that just might hold the elusive bug or enzyme capable of digesting large quantities of plant matter into ethanol.
Phelps's current batch of microbes, stockpiled in dozens of bottles of
silt, rocks and soils, was collected from Yellowstone National Park,
where the hot springs that draw millions of summertime visitors also
nurture microscopic life in their boiling waters. These bugs, in turn,
beckon microbiologists like Phelps, who seek a solution to transform
Earth's abundant cellulosic sources into a modern energy supply.
Yellowstone's warm waters offer the promise of microbes that can
rapidly and efficiently degrade cellulose—the woody, leafy matter that
makes up plants. Scientists hope to tap the power of these microbes for
industrial-scale consolidated bioprocessing of plants, including trees
and switchgrass, the species central to the BioEnergy Science Center's
research efforts.
BioEnergy Science Center
The hunt for this cellulosic "super bug" is part of a suite of efforts
under way at the BioEnergy Science Center, headquartered at Oak Ridge National Laboratory (ORNL). Since
being named one of three $135 million Department of Energy bioenergy
research centers, researchers at ORNL and its partner institutions have
quickly gotten to work.
DOE's ambitious goal is to replace by 2030
one-third of the nation's transportation fuel with cellulosebased
sources. At these centers, researchers are carrying out the targeted,
fundamental science needed to bridge the gap between the potential of
cellulose-based fuels and their reality.
Current microbes and enzymes are relatively slow at attacking plant matter's complicated and protective structure. Researchers will determine precisely the genes involved in the interaction of the microbes and enzymes to break apart cellulose. Other genes responsible for producing undesirable products, such as acetic acids, will be knocked out in the hope of, ultimately, developing the perfect ethanol-manufacturing microbe. Particular enzymes will be isolated as well and genetically analyzed, with a focus on determining the ideal formula of enzyme or microbe and enzyme to serve as the vehicle for cellulosic ethanol production.
Plants with Good Biofuel Sugars
Microbes, however, are just a piece of the puzzle. Other researchers at the Oak Ridge center are going through similar steps to develop plants with qualities most conducive to processing into biofuel. Similar to the microbial work, researchers will analyze thousands of genetically modified switchgrass and poplar tree samples in order to discover and develop the best varieties for ethanol production. As part of the process, the biofeedstock, together with the microbes and the enzymes, will be joined in a complex matrix of analysis and R&D in order to develop the best biofuel recipe.
On the biomass formation side, the partners will produce samples of plant material genetically altered to modify their cell walls for optimum breakdown into usable sugars. Such altered species might feature lower amounts of lignin—the substance that holds cellulose fibers together—or a reduction in the crystallinity of the cellulose. ArborGen and ORNL will be primarily responsible for creating and studying various altered trees, while scientists from the University of Tennessee, the University of Georgia and the Noble Foundation will take the lead in switchgrass research.
