The reality is that none of us can live in this world, and consume, without blood on our hands.
There are countless insects and small mammals killed in the raising and harvesting of food crops. There is large scale environmental loss. In certain regions the conflict is even more direct and brutal such as elephants destroying crops and then being shot.
Huge amounts of birds are also shot protecting crops. Why is the life of a chicken worth everything to a vegan, but that of a crow nothing?
Then there's the endless sea of roadkill from the transportation of it all.
Veganism seems to me to be driven by a strange desire to remove oneself from the natural cycle of life and death, only it isn't possible. For you to live, other creatures are dying.
I am in agreement that certain intensive husbandry practices are dreadful. I will not eat intensively reared pork or chicken, it's fucking abhorrent.
Botched slaughter is grotesque but I'm not overly concerned about slaughter done humanely Where I grew up I frequently saw chickens and sheep killed with a swift cut to the neck, and it's a pretty quick process. Pigs are admittedly trickier and I do think need to be properly stunned first.
I also think veganism is a total exercise in first-world elitism. Where I grew up, people live on less than a dollar a day and struggle to get adequate nutrition. The bit of animal protein (often in the form of gut stew, things don't get wasted and people are so poor than they butcher and consume animals that die of natural causes) that people do get access to makes all the difference.
A vegan diet would be a total health catastrophe for them.
I find it especially galling to hear a vegan in a wealthy country berate these people for using cattle for plowing and donkeys for transport, as being animal exploiters, before climbing in their car and driving to a supermarket.
A vegan diet is not natural, it's not healthy for many people and it's missing essential nutrients. In young women it's also an excellent cover for disordered eating.
