A study was published in the journal Cell Biology, Low Prevalence of Lactase Persistence in Bronze Age Europe Indicates Ongoing Strong Selection over the Last 3,000 Years. Europeans didn't evolve the ability to drink milk with lactase persistence until the past couple thousand years. People in the bronze age were not drinking milk anywhere close to how much people do now so drinking milk is literally something new to the human diet in the past ten thousand years and not something we need. So many people are not able to drink milk because of lactose intolerance, and lots more people lactose intolerance today, it's not a coincidence. Who knows how many people died drinking milk before generations became used to it, the fact so many people have lactose intolerance means we should not try and justify drinking milk from another species just because people started doing it. People do a lot of strange unhealthy things, doesn't mean we should do it. Milk is literally a new phenomenon in 250,000+ of human history literally for most of human history people never drank cows milk, only in the past couple thousand years have people around the world started to drink milk more commonly after developing lactase persistence.

People used to breast feed babies who need it for development but after that we don't need milk. The dairy industry profit from misinformation, government gives the dairy industry an advantage making plant based cost more. Dairy industry abuse animals who die under a year when their lifespan is 20+ years, the fact the dairy industry produce male cows obviously not useful for milk so they sent sent to slaughter which debunks the misinformation from the dairy industry that they don't abuse animals, sorry having baby cows killed because you don't need them is animal abuse. If hemp was treated like other crops the price would be cheaper, big money interests don't want plant based to be the cheaper option, because people often buy food based on cost and affordability.
