Questions without a good answer

What is the status of animals that we generate and culture so that we can use them? Are these animals the same as any wild animals or do we have more rights on their lives because we have made them?

This is important for me in research, but the same goes for the food industry and even fashion. How do we assign a value to these things?

I think of Antoine Saint Exupery who said:

"Tu deviens responsable pour toujours de ce que tu as apprivoisé. "
