Pre-Fall: Man and Animals were Vegetarians
Meditation: Genesis 1:29-30
And God said, See, I have given you every plant yielding seed that is on the face of all the land and every tree with seed in its fruit; you shall have them for food. And to all the animals on the earth and to every bird of the air and to everything that creeps on the ground—to everything in which there is the breath of life—I have given every green plant for food. And it was so. AMPC
Before sin entered the picture, both man and creatures were vegetarians. There was no killing nor was there any desire to kill for meat. I can't imagine myself not eating meat and would sort of feel a loss if I had never tasted meat. Grilled meat is a favorite of mine. But this appetite for meat, this practice of killing for meat was not God's original plan. God meant for man to rule over all the earth, but not harm His creation.
