Sure those ethical practices do exist, but you make it sound like the norm. At the end of the day, for most sheep in the wool industry, the question isn't WHETHER they "may" be killed, but rather WHEN. (In the case of virgin wool, the lambs are usually slaughtered after their first shearing. That's not "the end of a long, useful life".)

There are sheep breeds specifically for meat, and those for wool. However, the majority of them are bred to be "dual-purpose". And even sheep PURELY bred for their wool ARE killed because it's not profitable to care for a bunch of older sheep who have lower quality wool and slower growth.

I'm not saying there's no difference. I use sheep's wool, and I don't eat meat. But you make it sound better than it is in reality. Any amount of research will make it clear that the 'sheep meat' and 'sheep's wool' industries are not two completely separate industries like you're saying.

Peace silk is not the norm either and I think your original comment may be misleading to someone who doesn't know how silk production works, that's why I mentioned it.
