The farmer that can feed the pig if the pig is on her the pig will grow to an adult pig if she need something and she will kill the pig , the bacon are made in pig and other animals need to be free to the wild live with their family like people animals are the same they have food on their own.
If like fish get killed is fine because they are a lot they can have a lot of baby some on the land animals that can be not to exist.
Animals don't do anything to you, why are people killing them? The wild is their home?
