Bakken pipeline, yes; Keystone XL, no

Regarding the Keystone XL pipeline, I encourage Herald readers to research the tar sands oil production in Alberta, Canada.

For example, some websites show aerial views of the tar sands oil production. Tar sands oil production is a lot different than Bakken oil production: Producing oil from the tar sands requires clearing forested area in Canada, and mining the soil creates a large amount of wasteland. It looks to be very harmful to the environment.
