We ought to worry about meat agriculture before cow milk consumption. Meat ag presents multiple existential threats greater than diabetes, cancer, or obesity:

- Cramming thousands of animals together with their excrement and humans who work with it creates a convenient pandemic pathogen bioreactor

- Antibiotic resistance by abusing the same substance (just a different supply chain) to make animals grow faster at the expense of antibiotics ceasing to work in people

- Climate change, roughly 10%

- Pollution of air, water, and soil (Ever see what pig farmers do with shit? They liquify it and spray it in the air in shit lakes.)

- Inefficient use of agricultural land and resources that could feed more people and more cheaply
