One day, humans may not need breasts...for mother's milk
Thus far, artificial or GMO altered food products have created increased rates of obesity and other human DNA malfunctions...so these people want to start the degenerative process much earlier. If breast milk is healthier, there can be no 'replication' replacement is not 'replication'. Most early biology and chemistry classes teach this on the High School level. The mantra of Capitalism: if you build it they will come is quickly becoming the demise of humanity as we know it.
Simulated, or artificial, synthetic foods are for simulated, or artificial, synthetic people not humans.
