No...oil runoff is NOT the greatest polluter of our waterways. Chemical runoff (fertilizers and sewage) is the greatest polluter.
That's what anti pollution laws are for. Personal cars are way down the list and have made huge improvements.

Lets all go back to living in caves without fire and eating berries while the Chinese laugh.

Oh yeah...tar sands oil is ATTRACTIVE to developers at $50 a barrel and offshore oil is far cheaper and cost competitive with land and since 40% of all oil today is offshore oil..it is quite worthwhile to produce and getting cheaper all the time as new extraction methods are develeped. You've got to stop getting your facts from the whackos....if it were not profitable today...they wouldn't be drilling today.

As to pollution: Joint study by NASA and the Smithsonian Institution, examining several decades’ worth of data, found that more oil seeps into the ocean naturally than from accidents involving tankers and offshore drilling. Natural seepage from underwater oil deposits leaks an average of 62 million gallons a year; offshore drilling, on the other hand, accounted for only 15 million gallons, the smallest source of oil leaking into the oceans. (and much of that from the middle east where standards are much lower.)
