EARTH Magazine: Why is a Gallon of Gas Cheaper Than a Gallon of Milk?
From EARTH Magazine, August 18, 2016 -- In a comment published in EARTH Magazine, Robert L. Fares, a postdoctoral fellow at the University of Texas at Austin, explores what causes the cost of gallon of milk to be so much higher than a gallon of gas.
This phenomena is not merely a recent artifact of the decreasing cost of oil, rather it dates back at least a decade. Looking at all aspects of cost-relevant information, Fares explores the production and storage processes, consumer demand and packaging to break down and distinguish the factors that influence the costs of both gasoline and milk.

The August Issue of EARTH Magazine is the perfect read for any situation. This month's cover story looks at the illustrations that changed the way people think about the geological sciences. Also, we explore how scientists are using geomorphology and geochemistry to hunt down Hannibal's trail into Italy during the Punic Wars. We also go on safari with an interdisciplinary studies class and find out how the professor weaves geology into the lessons. All this and more in EARTH Magazine.
