Technology Advancement and Ethics: One reason humans differ from other animals is because of ‘ethics.’ Due to this difference, we believe that human beings are unique and that ethics are relatively stable. However, the factor that alters human ethics is the development of science and technology. In 2006, Japanese scientist Shinya Yamanaka discovered that mixing four chemicals with human skin cells could create undifferentiated stem cells. These cells are pluripotent, meaning they can develop into any type of body organ. Before this discovery, it was thought that such cells could only be produced through the combination of sperm and egg, but it was later found that they could also be synthesized artificially. Human philosophies, values, and ethics are trapped within technological advances. As science and technology advance, existing ethical frameworks are increasingly challenged. Now, traditional values that have been defended by gender distinction will experience severe conflict. - Jos...
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”
