Here's a lot of info about plant based alternatives to dairy milk.
Basically dairy milk sets a high bar for human health with overwhelming advantages which plant based alternatives struggle to get anywhere near.
The alternative industry has aggressively tried to lower or diminish the considerable range of health benefits of dairy milk to enable them to compete.
Whilst acknowledging the environmental impact of dairy which our farmers are doing their best to mitigate, apart from the much higher health benefits of dairy milk, plant based alternatives like almond production have been a disaster for both bee colonies and water tables in places like California, and soy is produced mainly in mass monoculture operations with much of it being sprayed multiple times before harvest with glyphosphate based herbicides which are linked to cancer.
