Your suggestion gives your question the appearance of a not-so-honest question.

> What do you suggest then?

The answer would depend on your convictions. It could be one or a combination of, for example,

- Tight national and international regulations (with teeth) to ensure animal safety and well-being, comparable to the transport of humans,

- Local-only growth,

- Alternative protein start-ups,

- Etc.

> but its cruelty against animals so lets kill them instead!

I could not find any instances where the OP suggested this.

edit: Found someone else who mentioned that, which doesn't make sense to me either - https://news.ycombinator.com/item?id=21637661

On the other hand,

> but its cruelty against animals

Then you would want to stop it in one way or another, no? What would be your suggestions?
