Genetically Altering Trees To Sequester More Carbon 279

An anonymous reader writes "Forests of genetically altered trees and other plants could sequester several billion tons of carbon from the atmosphere each year and so help ameliorate global warming, according to estimates published in the October issue of BioScience. The study, by researchers at Lawrence Berkeley National Laboratory and Oak Ridge National Laboratory, outlines a variety of strategies (PDF) for augmenting the processes that plants use to sequester carbon dioxide from the air and convert it into long-lived forms of carbon, first in vegetation and ultimately in soil."

First Superbugs, Now Superweeds 435

Finxray writes "Years of heavy use of the broad spectrum herbicide Roundup has led to the rapid growth of superweeds. They are spreading throughout North America, creating headaches for farmers and posing 'the single largest threat to production agriculture that we have ever seen,' according to Andrew Wargo III, the president of the Arkansas Association of Conservation Districts. From the article: 'The first resistant species to pose a serious threat to agriculture was spotted in a Delaware soybean field in 2000. Since then, the problem has spread, with 10 resistant species in at least 22 states infesting millions of acres, predominantly soybeans, cotton and corn. The superweeds could temper American agriculture’s enthusiasm for some genetically modified crops. Soybeans, corn and cotton that are engineered to survive spraying with Roundup have become standard in American fields. However, if Roundup doesn’t kill the weeds, farmers have little incentive to spend the extra money for the special seeds."
