Animal~about Bullfighting~

I'll introduce Bullfighting. Bullfighting is that a bull fight against a human or a dog. In Spanish's is particulary very popular. But its continuance seems most unlikely in recent days. Because it is criticized by public from animal protection's point of view. Bullfighters surely stick bulls with spears and swords. But should Spanish abolish the tradition that continues for a long time? Now it is natural we protect an environment and animals. Perhaps Bullfighting may be vanished by the public opinion.
