Jobs cause a conflict between unions and environmentalists: recognizing that regulations cost jobs

This is one place where unions and environmentalists don't mix. Private sector unions have different interests than public sector unions, and it is somewhat surprising that the two groups haven't separated from each other. From Fox News:

Nebraska is the site of the the most intense debate over the proposed Keystone XL pipeline, a project so controversial, State Sen. Ken Haar stood Tuesday before State Department officials and said, “You don’t give a damn about Nebraska.”
Haar was cheered loudly.
TransCanada wants to build the 1,600-mile oil pipeline from the oil-rich Canadian province of Alberta to the Texas Gulf Coast. The multibillion-dollar construction project will bring much more Canadian oil into the U.S., but more important to labor unions, it’ll bring jobs.
“A lot of our members are losing houses," says Ron Kamininski, business manager of Laborers Local 1140. “They’re losing their vehicles. ... It’s a struggle to keep food on the table.”
To Kaminski and so many other in the building trades, Keystone XL means work.
"We’re ready to employ 13,000 Americans on the construction and employ 7,000 manufacturing workers,” TransCanada Vice President Robert Jones said. “The pumps are going to be made in Oregon. The motors are in Ohio. The pipe in Arkansas. So all of America is going to be impacted by this project.”
This comes at a time when the national unemployment rate lingers above 9 percent, but not everyone thinks the pipeline is worth the environmental costs. . . .
