Libertarians would ____________________________________________________________.
Libertarian societies are comprised of competing agents which aspire to pick the lowest hanging fruit until exhaustion. As the price of the fruit rises in price, the effort and technology applied to harvest said fruit increases, as it can be sold for more. This continues until exhaustion, at which, belatedly, efforts are made to harvest and utilize the next lowest hanging fruit. In each case, the world becomes a less richer place.
So the people living there would first attempt to defraud anyone they could to take title of their land in effected areas as they got the hell out of there. Then the people who foolishly invested in the toxic assets would strip the assets there clean to recoup their losses, especially the trees. Low income people are offered free living in the abandonded areas if they work at the newly repurposed factory areas, now much cheaper to run with the complete collapse of the local economy creating a new 3rd world along the gulf. This increases pollution making the gulf catastrophe worse. The impoverished parasites there complain about their 35 year lifespan and the ocean continues getting worse because it was nobodies responsibility to fix it.
E: hey, in the ole USA we did all 3!
