Opponents of the Line 3 oil pipeline across Minnesota continue to work to halt construction. Tribes, environmental groups and celebrities continue to devote considerable energy against the project that Enbridge Energy, the company backing the pipeline, says is more than 80 percent complete. Potential environmental disasters, inadequate tribal consultation, and further reliance on a climate changing energy source are all issues in the mix. The company says the project offers thousands of local jobs and a safer alternative to the aging existing pipeline.
