Completion of the pipeline would add to the destruction of the natural beauty of the Canadian tar sands sites, including First Nation property.
The pipeline company has a horrible safety record, with 14 recent spills. A spill or leak on this pipeline route would endanger vital natural resources in the USA, including the Ogallala aquifer. Previous spills of dilbit have produced severe long term damage, on the Kalamazoo River and in Mayflower, Arkansas.
The financial benefit of the pipeline would accrue largely to TransCanada only, with just 35 permanent jobs created in the USA.The Tar Sands product is destined for export, thus not benefitting US oil security.
The refinery site on the Gulf Coast would suffer more air pollution, and greater deaths in this “cancer alley” region. Construction of the pipeline would commit the USA to 50 years of further production of fossil fuels, when the IPCC scientists have clearly stated we must quickly convert from these fuels to clean, renewable energy sources.
