Even in the growing and harvesting of plants, large amounts of animals get killed in the process. The moles underground, the rabbits and hares that eat the plants, the rats and snakes that shelter in the piles of harvest etc, they all have to be killed en masse to ensure a good harvest. Given this fact, veganism appears to me like a refusal to accept the reality that this world is a harsh one full of chaos. I prefer to focus on sustainable consumption as the reasonable balance between the two extremes of veganism and American fast food.
