True, I could survive off of shellfish. I could not survive off a vegan diet, since my family has a history of diabetes and complex carbs are off the table and I have a fish allergy. I could conceivably live on a vegetarian diet if I supplemented it with dairy.
The best option would be synthetic meat, real meat that is grown on a protein scaffold using stem cells. This would remove the need to kill animals and give the nutrition from meat. However until this becomes a viable option economically I think the question of killing animals for meat is an ethical question that is valid.
As for the deer issue, those things are vermin. They have exceeded their carrying capacity and are eating other animals out of their habitats. In some areas they have grown so plentiful that they are starting to starve. Why not a kill a couple and eat them?
