I guess you would rather Dalton spent a few more billion on windmills - that produce something like 10% of what they are supposed to. See

Whatever you may think of windmills, I'll keep on not mentioning them, OK Don Q
Sox?
Spend it now is cheaper than spend it later. BP couldn't afford the additional measures that would have managed its risk down to say 1%, like pre-drilling the relief wells, or having a tested containment cap ready to go. Too expensive; not cost-effective. The cost of cleaning up mine (often copper) waste in Montana far exceeds the entire total of all the profits of all the mining companies who left it behind.
Who's cleaning it up? The taxpayers who believed copper was cheap enough to make pennies out of, if it meant jobs. Heck we coulda used 'em as quarters, but no one asked. The only way not to have clean-up costs is not to make messes in the first place. The only way to keep them cheap is to keep the job clean as you go. Assuming you're not just gonna cut and run like the old-time mining companies. Or Syncrude?
When all the left-behind crap was way out in the boonies, who cared? But there'aint no boonies any more: sushi in Japan is being threatened by the Gulf spill. So's your commuting cost. Point is all those things have historically been priced too low, because once the waste was washed into the sea/downstream/up the stack/into the tailings pond, it was an 'externality'†.
Well, guess what? There ain't no old-fashioned externalities no more. There's always someone living downwind, downstream or down the block who's gonna resent you/me dumping our trash on them and make you clean up. If we aren't smart enough to figure those clean up costs—for intentional and accidental messes—into the bottom line, let's try to have faith the guys at the business schools will, or it will be an awfully ugly cheap, dirty future. A classy, and clean one appeals more, even if pricey. That's what all the enviro stuff's about—shortening the clean-up chain, so people pay for their messes up front. And if prices go up, so be it: if that's the End of Lif As We Know It, no one woulda reproduced after the invention of money.
Anyway, don't let Toronto cops catch you w/ that lance before you find a windmill to run at OK? Oops. I said the woid; where's the duck?
†I realize I'm likely mis-using what is a technical term in Ecomomics and someone is likely to correct me. I hope the meaning I derived from 'externality's origins in English is nonetheless clear. You can trust me to attempt to explain at even greater length if it isn't
