Stern, in Toronto this week to present his argument that environmental stewardship need not mean a stagnant economy, said “The costs of action… are much less than the costs of inaction.”

Earthquakes are highly unusual in eastern Colorado, raising speculation that it was a “frackquake” — a man-made earthquake stimulated by the disposal of contaminated drilling water in deep injection wells. This disposal technique forces wastewater generated from hydraulic fracturing (fracking) deep into underground rock formations, lubricating layers of rock that would not ordinarily be subject to movement.

Earthquakes are so rare in eastern Colorado that the U.S....
