Economist: In order to decide what to do about protecting the ozone layer, we must determine the monetary amount of the economic resources that we would willingly expend to protect it. ββββ β βββββββββββββ βββββββ ββ β βββββββββββ ββ βββ ββββββββ βββββ ββ βββ βββββ ββββββ βββββββββββββββββ βββββ ββββ βββ βββββ βββββ ββββ βββ ββββ β ββββββββββ ββββββββ ββββββ ββββββββ ββ βββββ βββ βββββββββ ββββββ ββ ββββββ βββββ ββ βββ ββ βββ βββββββ ββββββββ βββββββββ ββ βββββββ βββ βββββ ββββββ ββ βββ βββββ βββββ ββ ββββββββββββ βββββ ββββ ββββ ββββ βββββββ βββββ βββ βββββ βββββ βββ β ββββββββββ ββββββββ ββββββ
The economist concludes that the ozone layer has a calculable monetary valueβi.e. the amount of money we would be willing to spend to protect it. This is supported by the claim that we wouldnβt spend all of the worldβs economic resources to protect the ozone layer. This leads to the sub-conclusion that there must be an upper limit to how much the ozone layer is worth.
The economist concludes that a certain value is calculable because there is an upper limit to that value. However, even if there is an upper limit to the ozone layerβs value, that still doesnβt establish that the exact monetary value of the ozone layer can be calculated.
