Sanctimonious pessimists. Their wailing and gnashing of teeth is an act as they seek to control the commerce that has made them safe and comfortably positioned to snipe at things they do not understand.
The thought process is more than a little flawed.
There have been great strides in our ability to produce enough food due to various efforts at improving the food that we grow. Since Mendel purposeful hybridization has occurred with great success. It is a leap too far to suggest that somehow cloned animals are going to become the standard for food production.
I do not think that man knows everything for that is folly. But I do think that man has the God given ability to improve our every day life.
A “clone” is a “twin”.
End of story.
