I was lucky enough to do a lot of scuba diving over a three year period about 8 years ago. In their natural environment fish are fascinating, and their interesting behavior and interaction with each other and often humans, too, suggest a greater level of awareness and intelligence than they are generally credited with. I was a semi vegetarian before I started scuba diving – no meat or dairy but I still occasionally ate fish. The more I dived the less fish I ate until I just couldn’t eat it anymore. Now I am a complete vegan thanks to getting to know our marine wildlife up close.
