Even if it was enormous enough in fines to put them out of business, the industry as it is with all its inherent risks will still exist because that is still legally allowed. Forget a fine; outlaw the behavior that lead to the issue. Incentivize new emergent behavior instead of just hedging.
The behavior that leads to the issue is individual consumers driving cars. Outlawing this would nuke demand for fossil fuels which encourages risky well drilling. But since 99% of Americans drive they tend to get very unhappy about the prospect of banning the vroom vroom. This is a real and challenging political problem. We can't get around it by pretending that corporations drill for fun.
