There has always been much debate on whether vegans should eat honey or not, and I never quite understood it. Put simply, bees are animals.
Bees make honey to feed themselves. The honey they create throughout the year is used to feed the colony throughout the winter. When the hive feels threatened, guard bees release a pheromone that tell the others there is an intruder, thus attacking. When a beekeeper takes honey from a man-made hive, they puff smoke into it, dulling the guard bees senses so there are no pheromones released. The smoke also has another effect. It puts them in “panic mode” which causes them to eat their honey in the case of relocation to build another hive. Creating man-made hives and stealing their food is nothing short of exploitation. The bees not only have to work harder to create more honey (after the taking of humans, and eating of confused bees), but this will inevitably result in a shortage of food for the winter. I realize bees aren’t the first animals people think of when exploitation comes to mind. But the reasons are valid why honey should be avoided.
As for marine life, to the chagrin of seafood eating “vegetarians,” fish are animals. They have central nervous systems which can cause them to feel pain. Therefore, prawn and mussels would be capable of feeling pain, just like any other aquatic animal. Evolutionarily, it makes sense for them to feel pain. They will know what to avoid to stay alive.
