Well, Nature boys (and girls, and whatevers), the oil companies would not exist if people didn't use their products or products made from oil.
They wouldn't even risk the CAPEX to get a drop out of the ground without a market for the oil.
IF there is environmental damage done, it is done in pursuit of a product in demand, and those who demand and use it are the ones doing most of the alleged damage, but oil companies don't like dumping money on the ground, or in the water, so spills are something we strenuously try to avoid, even little ones (an ounce is too much to waste).
Now they might find someone out there who has never worn a synthetic fabric, never used anything made of plastic or taken a drug whose origins were in a barrel of oil or piped in natural gas, or even just shipped using motor fuels, but those folks are likely few in the world, compared to the "guilty".
So, with billions of small contributors to any claimed 'damage', why single out the people who merely provide the means to live comfortably, to transport people and goods, and even manufacture those goods, versus the ones who use them?
