(Note: This is the final of a six-part series on "Bakken Spinoffs" airing Thursdays through January 9th on "Montana Evening Edition.")

The flares from oil rigs light up the night sky in the Bakken region.

Burning off these polluting gases is a by-product of extracting the oil in fracking operations.

Not only do the flares increase the emissions of the rigs, the oil companies are wasting natural resources that could be sold.

It has been a cost of doing business in the fracking world.
