Mechanics That Are Beyond Us

We think we should be able to drill oil, mine coal, or tap natural gas wherever we find it, no matter how difficult the conditions. The technology for surface mining of coal--used in mountaintop removal--is fairly simple, if drastic environmentally. Oil drilling in deep sea, however, must use highly sophisticated technology.

Up until the Gulf disaster, the industry assumed that the redundant safety devices would prevent blow-outs. But they were using the technology at greater and greater depths, both of water and of earth beneath it. Deepwater Horizon is far from the deepest well, however.

They had four devices, each of which, alone, was supposed to prevent a blow-out. The first was a cement plug just above the tapped oil, the second, a similar plug several thousand feet below the sea floor (the oil is 13000' below it). The third was the blow-out preventer, which was supposed to be able to shut off the pipe, and the fourth was a shear in the preventer, that would snap off the pipe and clamp it shut.

All of those safety devices failed. It's argued that a second shear, often installed in a blow-out preventer as back-up, might have worked. It might have.

But, blind faith in a blind shear isn't just blind; it's hubris. Perhaps the technology, as sophisticated as it seems, isn't yet up to the task. Considering that an offshore well like Deepwater Horizon can commit ecocide on a huge scale, we can't settle for 9 out of ten, or 99 out of 100. We have to be absolutely sure that there will be no accidents, or that we can clean up any accident, regardless of size, before any environmental damage.

Or, build solar panels and wind turbines like mad.

I predict we won't do either. After all, well-drillers need jobs.

The Roman Empire contributed to the desertification of North Africa (it had been its granary), because it needed food for its huge population; it deforested the Mediterranean because it had to keep its baths good and hot. Wasteful patterns, once established, are hard to change. It's likely that Rome's ecological wastefulness contributed substantially to its impoverishment. The good counselors of Ephesus pointed out the danger of stripping the hills of trees, but the city's port became silted up anyway: probably, contractors to the baths had to keep cutting wood, until it was gone. And then Romans did the same thing in Rome and Ravenna.

Will we now poison the whole world in our inability to leave oil and coal behind, and use renewable, non-polluting energy?

The oil companies--and the coal companies--need their profits; the drillers and miners need their jobs. The companies are politically well connected. What do you think is the most likely outcome?

How can we change it?

Scream bloody murder--of the Earth. It's that serious.
