Fresh food needs to be "harvested".

You catch it. "Process (bleed, gut, and portion)it". Cook and eat it.

Good experience for young people to know where their food comes from.

The only thing that may be offensive if you force it on those who do not eat pork because of their faith.

How do you catch fish? With a hooked line, net or spear?
How about rabbit and fowl(duck, pheasant, geese, etc.)?
Is it an issue of violence or cruelty?
