We started out making our own farm for animals (pigs + chickens) but we figured we actually liked the little buggers (what you describe as watching them grow etc, for me, especially with pigs, makes them the same level as dogs and the hypocritical west is as the hypocritical west does which I couldn't really stomach) and went vegetarian anyway. Don't miss meat at all (don't actually like it anymore), but that's not the point; the life is good if you like that kind (nature, fresh air, quiet usually if you have a small farm) of thing with or without eating meat. We have fresh eggs from our chickens and fresh fruit and veg without pesticides and water from our own well.

We started growing hops (& more apples) for the brewery and it is really nice. It isn't for everyone but if you like it then there is no reason not to if you are a programmer (which I am). You don't have to go full in with a complete farm, just growing / rearing your food partly is a nice feeling. It also is, at least here in the EU, much cheaper if you don't go full in (and you wouldn't have to if you don't have to make money); everyone wants to live in cities (I feel left out as I hate them :), so the country is empty and land is cheap. As are houses (depending on the location). In a lot of countries you would not even need a house per se; just a container or caravan would suffice (if only I had known this when I was young).
