Why are New Zealand beef bones and sheep bones cheap?
There are many sheep and beef. Wellington, the capital of New Zealand, is located in the southwest of the Pacific Ocean. Cattle bones and sheep bones are cheap, because there are many sheep and beef in China. And in New Zealand, they don't eat animals' internal organs, heads, feet and things with bones. In particular, the number of sheep in New Zealand is dozens of times that of the population, and most of them are exported.
