Why all of a sudden is this happening? Is this the result of something called tampering? God only knows. Although God's original diet was meatless, ("God said, Behold, I have given you every herb bearing seed, which [is] upon the face of all the earth, and every tree, in the which [is] the fruit of a tree yielding seed; to you it shall be for meat" - Genesis 1:29), people still should be free to choose if they want such a diet or not. It may be the healthier diet, but forced diet is not of God.
