As Kim said, this kind of thread comes up at least once a year. It often has Japan as it's main Villain. I've wondered why the remaining European whaling cultures don't get the attention. Maybe it's a numbers thing (Japan harvests larger numbers?), or maybe Japanese seem more foreign, maybe it's a combination of both.
Of all such threads I've read, I think this one might be the most civil. Good points have been made on both sides, with some nonsense thrown in now and then.
A couple points I'd like to address...
First, as Kim alluded to, since Japan depends a great deal on the sea, the country puts a great deal of resources toward understanding and protecting the seas. Furthermore, the fishermen are a powerful group, economically and politically (as divers can attest to).However, I'm with Andy on the Scientific research label seems dodgy.
Second, people find it hard to understand why a culture would want to consume whales. We look at whales and hear music and imagine kids movies. Older generation folks here in Japan see something that is on the menu. Period. I think the younger generation here likely feels differently since younger folks have never eaten whale.
