The importance of understanding where we have been so we do not make the same mistakes twice can not be understated. Understanding the role resources like coal and fossil fuels played in our societies development and prosperity help us to comprehend where we would be without them, likely burning whale fat in our lamps and heating ourselves with wood stoves riding horses and spending most of our time trying to feed ourselves. At the same time we see the consequences of our decisions through changing climates, decreases in biodiversity and historical photos that depict where a mountain once stood but now there is only a mine. History forces us to recognize the impacts of our decisions. Liza is a professor at the University of Alberta where she teaches environmental history.
