Burning oil isn't a problem, in fact most of it isn't burned. Depending on needs, only 35 to 45% or the oil we use is "burned" for automobile fuel and heating oil. The rest is used as a chemical feedstock for medications, plastics, fertilizers, fibers, water filtration and a multitude of other life improving products- even essential for the extreme conditions lubrication required for wind turbines. Bottom line oil is 100% natural, and since no pesticides were used on the algae it's organic.
