Have you seen how fish are able to swim in a school so precisely relating to their fish-fellows and never clumsily bump into one another? That's because they have a highly developed sense of feeling in their bodies, which enables them to feel not only the movement of the water against their skin but the presence of other beings who are close. They certainly are not cold-blooded in the sense that they are dull, insensitive, and have no feelings.
Most of the food crops raised in the world today are fed to livestock destined for slaughter for us to eat, and most of the water used is used to raise the food crops that are fed to those animals. It has been estimated that, because of the extraordinary amount of grain it takes to raise food animals, if we reduced the amount of meat we eat by only ten percent, that would free up enough grain to feed all the starving humans in the world. So when we choose to eat meat instead of vegetables, we are choosing to take food away from others who are hungry.
If we weren't so dirt-conscious, we would obtain adequate vitamin B12 from soil, air, water, and bacteria, but we meticulously wash and peel our vegetables now - and with good reason, as we can't be sure our soil is not contaminated with pesticides and herbicides.
Fishing is not a benign activity; it is hunting in the water.
