If you’re alone on an uninhabited island, you don’t need money; you only need resources and labor to process those resources for survival. In other words, there’s no need for an exchange-based economy. The exchange of goods led to the development of an economic system that dramatically increases efficiency and productivity. The monetary system was created because society consists of many people living together. To facilitate exchange, value had to be measured, and a price assigned to that value. The foundation of wealth is built on production and exchange. We all rely on others to survive. - Joseph’s “just my thoughts”
A lifetime of tuna is about 10 years. They don't have any muscles to suck the water up and constantly have to be moving their bodies to breathe in the water. So, they can not be sleeping or resting a lifetime of tuna. Even going to sleep, tuna must keep on moving in a sleep-like state until their deaths, if they stop moving, they will be dead soon. According to the attribution, tuna can swim in water at over 100 km/h speed, they need so many other fishes as foods to supply the wasted energy for this fact. The tuna is paid for the huge price of becoming a top-rated predator. But I'm not a top predator, so why do I eat so much? - Joseph’s “just my thoughts”
