This paper explores both the necessities and the options for an agricultural system in which no animals are killed by reviewing existing literature. It first identifies a causal chain which can be labelled as vegan wave and which might generate a consensus that animals should not be killed for human consumption. By raising issues of nutrient supply, grassland management and beekeeping, the paper shows that vegan-organic agriculture, vegan-conventional agriculture and post-lethal vegetarian agriculture are three options for such a pathway. Yet, many technical and socioeconomic questions still need to be resolved.
