In a pair of commentaries, the pros and cons are considered for Enbridge's application for a certificate of need for its proposed Sandpiper crude-oil pipeline. The line would convey up to 375,000 barrels of Bakken crude oil per day over a distance of 610 miles from Beaver Lodge Station, N.D., to Superior, Wis.:

• Sandpiper will be safe, provide jobs in northern Minnesota, remain environmentally sensitive and help reduce our reliance on imported energy, writes Enbridge's Paul Eberth.

• Sandpiper should be denied because the detriments to humans and the Earth from greenhouse gases will outweigh the economic benefits, writes Stan Sattinger of the climate-change group MN350.
