“There are probably well over 100 academic efforts to use genetic engineering to optimize biofuel production from algae,” said Matthew C. Posewitz, an assistant professor of chemistry at the Colorado School of Mines, who has written a review of the field. “There’s just intense interest globally.”
Algae are attracting attention because the strains can potentially produce 10 or more times more fuel per acre than the corn used to make ethanol or the soybeans used to make biodiesel. Moreover, algae might be grown on arid land and brackish water, so that fuel production would not compete with food production. And algae are voracious consumers of carbon dioxide, potentially helping to keep some of this greenhouse gas from contributing to global warming.
And people that think it is going to destroy the ecosystem:
“We are not saying don’t do this,” said Gerald H. Groenewold, director of the University of North Dakota’s Energy and Environmental Research Center, who is trying to organize a study of the risks. “We say do this with the knowledge of the implications and how to safeguard what you are doing.”
At a meeting this month of President Obama’s new bioethics commission, Allison A. Snow, an ecologist at Ohio State University, testified that a “worst-case hypothetical scenario” would be that algae engineered to be extremely hardy might escape into the environment, displace other species and cause algal overgrowths that deprive waters of oxygen, killing fish.
