"A genetically engineered, freeze-tolerant eucalyptus tree is moving closer to receiving approval from the U.S. Department of Agriculture, amid concerns about the tree’s possible negative effects on the environment.
The USDA has proposed lifting restrictions on commercial production of the trees, based on a draft environmental impact statement that concluded the trees pose few significant environmental risks. Planting the trees would “either not differ or may be slightly worse from those caused by the cultivation of planted plantation pine,” the report said.
Brazil approved a genetically modified eucalyptus, created by biotechnology company FuturaGene, for commercial growth two years ago. But this would become the first genetically engineered tree approved for commercial use in the United States."
