"Attention has focused on oil insecurity, and rightly so, but it is not the same as food insecurity. An empty gas tank is one thing, an empty stomach another. And while there are substitutes for oil, there are none for food." –Lester R. Brown, Plan B 4.0: Mobilizing to Save Civilization.
The Huffington Post article "Plastic Water Bottles Causing Flood of Harm to Our Environment" references EPI's research on bottled water. Author Norm Schriever writes, "The Earth Policy Institute factors the energy used to pump, process, transport and refrigerate our bottled water as over 50 million barrels of oil every year. That's an insane amount of resources for something that is completely unneeded."
