Unsure if I fully agree. On one side, yeah cows are exploited. But they get a safe life, with medicine and treatment for illness and physical issues (hooves). Access to food without concern of predators, safe place to sleep and give birth.

Cows are one of the most successful animals in the world because they're a resource for humans. They are not allowed to go extinct.

I'd say humans are by far the best thing that happened to any domesticated animal.
