Humans won't die of malnurishment if they exclude dairy products from their diet. With plenty of plant-based food choices available there are many other nutritious alternatives - it just requires a little education and a change of attitude. Today, 'Big Dairy' is so powerful it competes with 'Big Food' and 'Big Pharma' for world domination. Of course, issues like global warming are of concern to us all (Co2 emissions from livestock), but deliberate cruelty to innocent animals is unforgivable. There are no excuses. Perhaps we should 'think before we drink' cow milk?
