The animals are gods creatures too
He told us to eat plants!
He also said that we have dominion over the birds in the sky, the fish in the sea, the cattle on the land, and all other creatures, Genesis 1:26. If you take a life of an animal for food it shouldn't be done casually and without heart or thanks. Even the animals that you eat that you did not kill that animal still gave its life so that a person can receive nourishment from. I don't view dominion as a selfish thing but as a part of God's Earth that He gave to us to watch over. I obviously have eaten meat from animals that I have not killed but I do try to make an effort to have the majority of my meat be from animals that I either killed myself or helped in the process with. For example, my parent's ranch that I grew up on has livestock and some of that livestock is used for our food supply. Nothing is ever wasted and there is a lot of respect that goes towards those animals.
