Blowing the hole up, would render the oilfield useless (uncalculatable instability), and
BP looses the investment into drilling the hole.

Thats why BP tries to seal it.
It offers the option to reactivate the (working) drill.

In the end we are all consumers of oil-based products.
BP is just one of the companies offering a service we all use.

Its more an issue of missing regulation of underwater oil exploration.
The government should quickly impose requirements to have tripple proved
savety systems to these drills.

(BTW, Louisiana LIVES from the oil industry.
Its the single most important industry there.)
