If one where to simply list behavior and action from having a positive effect on the environment, neutral, or negative, it would not be that hard to see that general farming is on the negative side. It can be promoted as a better alternative to even worse things but to even cross the line into neutral one has to go elsewhere than just cutting out meat of ones diet. A common thread in environment positive food is that it moves the environment towards a better balance and away from mono-organisms. Open fields with pasture raised livestock has this effect when used proportionally in countries where single-crop and forest has started to reduce the bio diversity, such as in Sweden. Fishing in overpopulated lakes helps so that less common species don't get out competed or eaten. Honey from bees has positive side effects that sugar canes do not. A bit less studied but possible areas is also seaweed or mussel farms since those filter water and can reduce eutrophication (through the health aspects makes this a difficult balance). Veganism isn't the answer simply because that diet alone does not have a net positive effect on the environment, and the reduction compared to even worse diets isn't impactful enough. We have to start actually looking for actions that have a positive effect, rather than simply going from bad to slightly bad diet.
