In a victory for the climate, public health and endangered species, the Fish and Wildlife Service has taken action which could interfere with TransCanda's plan for fast-tracked approval of the Keystone XL oil pipeline. The Center for Biological Diversity finds a University of Nebraska researcher is not being allowed to use his research permit to help TransCanada clear the way for the pipeline by physically relocating the American burying beetle from its habitat. The decision could delay construction even longer because beetles can only be trapped and moved in the spring and early summer, when they are active.
