Much of the extra price you pay for the synthetic goes to pay for the extra energy using processing to produce it. Dino is just that, it is already there in the crude, just needing to be separated out. Other fractions are then cracked, oxidized, esterified, etc. to produce synthetic oil, gasoline, antifreeze, brake fluid, and a host of non automotive products including the polyethylene bottles the oil comes in. It is easier on the environment to produce the dino.
On the other hand, those that use extended change intervals with the synthetics, may be helping the environment, consuming less crude, producing less used oil, spilling less, etc. After each of my oil changes, there always seems to be entirely too much oil soaked newspaper to go to the land fill.
