Sierra Club calls for a moratorium on genetically engineered trees

From:  http://www.sierraclub.org/biotech/trees.asp

...action is needed both at home and internationally to create a worldwide moratorium on the further development and planting of GE trees at least until an effective framework for public debate, unbiased scientific evaluation, and regulation in the public interest - with the goal of preserving biodiversity - can be brought into being.

This means that the mass plantations of genetically engineered trees for cellulosic biofuels in the area of genetic engineering must come to a halt until better and more thorough science becomes available.
