Well well, respect to individual's choice; I for one belief in slow evolutionary modifications one at a time. Speaking one way meat regardless of what is the source will bear the same sin, but the bigger question is are we ready! I mean is all our body prepared to gulp in those foreign proteins that none of our ancestors may had introduced into their body. Protein in milk, some Jha's theory that early Sub-continental civilations used to consume beef do not convienence me to admit that evolutionary I am ready to consume it. Looking at BSE, it is a prionic disease, small proteins that is unrecognized by the body, there is this recent one associating red meat with increased incidence of cancer and other associated diseases. However, having said that it is again all upto an individual, as for my evolution reached upto; from grandparents to now; Veg-Cheavon--buff,chicken,pork--?
