Aasof’s Reflections

This week on Facebook: My attention turned to fish and the ever increasing global demand for sources of protein. I often mention in conversations with a friend what I call my Tesco Tuna Test, the contention being that cheap tins of Tuna — usually sold as 3 tins wrapped together — is only possible when the supply continues to exceed (or match) the demand. The demand is clearly going to increase, along with the price and the eventual reduction in the global supply of supply of tuna. If the TTT provides a measure of global overfishing by the price of wrapped tins of tuna divided by the weight of tuna therein, it will also increase. It’s difficult to predict what number in the TTT would represent global overfishing, especially as that number has already been reached, but perhaps it may represent the rate at which global overfishing is occurring. This assumes that supermarkets, their suppliers and consumers of tuna, actually care as the TTT has yet to begin a recognisable (and inevitable) exponential rise. Read more of this post
