Drinking cow milk based on grass is better for the environment than artificial milk based on soya and palm ingredients, according to British researchers. This among others because soya meal from land that not long ago was converted from wood or natural grass land to arable land has a high carbon foot print. Also the production of artificial milk based on soya and palm is less environmental friendly than the production of milk by cows, in particular when the feed ration of cows does not contain ingredients from soya or palm.
