    Hi there - we appreciate that the “just filtered” part of our title has drawn a few comments and we want to address it. First off - you’re right; you could say lots of things are filtered blood products, including urine and even the carbon dioxide we breathe out. We decided to make this video because we believe most people, including ourselves, don’t think about how the same thing is true for a substance a lot of us drink every day - milk from an animal - and that communicating that fact would lead folks to a different appreciation of what milk is. Secondly - you’re also right; we didn’t fully convey the amazing things that the mammary gland does. Almost all of the precursors to the stuff in milk DO come from the bloodstream, but the special cells in the mammary gland transform many of them into their final milky forms, which we simplified in the video as “do some chemistry on them” and in the title as “filtered.”

      but it's not lactation.
      the process of the milk generation is not lactation. this video explain how the milk is generated.
      probably indeed udderly cringe worthy, you talking about two different thing.

    It's not "impressive" how much milk that cow produced, it's disgusting. That poor mother has been bred to create way too much and will, like all dairy cows, be repeatedly forcibly impregnated and have her baby taken from her so people can hook painful machines up to her nipples and take it for selfish humans because they enjoy the pleasure of that substance in their mouth. All mammals produce milk, including dogs, cats, pigs, rats, and humans and that milk is meant ONLY for that mothers baby. Once the baby is weaned they will never drink milk again. Stealing the milk from a different mammal species and drinking it ourselves makes zero logical sense, and it turns out that dairy is REALLY bad for our health. It's basically miracle grow for tumors and contains high amounts of fat, cholesterol, and naturally occurring hormones like mammalian estrogen which screws with our own hormones. Not to mention the actual red blood, pus (somatic cells), and feces contained in milk because the cows get cut by the machines and bleed, get infections like mastitis that isn't treated, and live in horrendous conditions so therefor have feces going all up their legs from being forced to walk in it. And the real potential for casein which breaks down into casomorphin in our system to make and keep us addicted.
    Dairy is an unnecessary and cruel "product" that exploits innocent sentient beings for pleasure and/or greed by hijacking the female reproductive system of a non-human mammal. This video was well made, informative, and important as more people need to understand the biology of animals, especially the ones we exploit. We have altered cows and other "livestock" to the point that just living in their bodies can be torture. I love Minute Earth, and as I said, this video was great. The ending was disappointing and sad, but of course, it also could have been worse. When covering these topics if you don't want to spread a compassionate, animal rights, or vegan message it's best to stay as neutral as possible. For most of the video that was accomplished but the end ruined it by calling it impressive and making a joke. The suffering of billions of animals is not funny. I know this comment will receive a lot of hate, arguments, or complaint. There's no need to defend Minute Earth as I will still watch, subscribe, and like. But I'd like everyone to consider also, that being a non-vegan environmentalist is hypocrisy. Ignorant at best, apathetic at worst. In the case of apathy you cannot truly call yourself an environmentalist when animal agriculture is the single worst human behavior for the environment. Being vegan is the easiest way any one person can make a huge impact on the environment, but also the world in terms of ethics, health, and even human rights. Peace

      Try plant milks! Rice, hemp, flax, almond, oat, cashew, soy, coconut, pea milk, macadamia nut, hazelnut, etc. If it's a nut, seed, or grain chances are it can be turned into a milk and also used for cheese! These can also be flavored any way you like, sweetened or unsweetened. There's plant version of all your dairy needs: coffee creamer, yogurt, sour cream, cream cheese, ice cream, butter, sliced or shredded cheese, soft cheese for spreading, gourmet cheeses like Miyokos, and it all can be made safely at home as well! Brands include: Chao by Field Roast (my favorite), Follow Your Heart, So Delicious, Kite Hill, Treeline, Go Veggie, Tofutti, Miyokos, Silk, Daiya, Teese, and many, many more!
      Dairy is also super unhealthy for you so leaving it out of your diet can definitely benefit you! (:
