I’m responsible for the death of tens of thousands of animals. Granted due to the size of pigs and cows it’s likely only a single digit number of mammals, but it was also only done for the trivial purpose of my own culinary pleasure. Imagine the number of animals need to balance out the moral calculus of not my food preferences, but life of a human. The excruciatingly high standard to which we hold medical animal research is indefensible to all but the strictest vegans, and in the context of our omnivorous culture an absolute travesty.
