exhaustibility การใช้

Traditional areas of environmental and natural resource economics include welfare theory, land / location use, pollution control, resource extraction, and non-market valuation, and also resource exhaustibility, sustainability, environmental management, and environmental policy.
Specifically, this shows that exhaustibility does not occur until these factors weaken and play out : the availability of substitutes, the extent of recycling and its feasibility, more efficient manufacturing of the final consumer product, more durable and longer-lasting consumer products, and even a number of other factors.
On the one hand, a material ( and its resources ) can enter a time of shortage and become a strategic and critical material ( an immediate exhaustibility crisis ), but on the other hand a material can go out of use, its resource can proceed to being perpetual if it was not before, and then the resource can become a paleoresource when the material goes almost completely out of use ( e . g . resources of arrowhead-grade flint ).
