This study is sure to be ignored and its author's reputation smeared. Too many paychecks depend on the fossil-fuel-is-evil theory.
Like WMD, people think of weaponry that has a trigger or shaped like a bomb rather than Bio-Warfare. We tend to think of oil for cars, machinery etc. while forgetting how something like a zip-lock bag to childrens toys, to parts of cars or anything that is plastic - that is actually what we are addicted to. You can purchase several different oils for your car, lawn mowers etc. that are man made and very good. Packaging with plastic is really a problem as it is wasteful and costly.....and it takes barrels of oil to produce it.
