While condemnation from conservation groups has eased in the three years since Japan's fleet exited the Antarctic, the country's whalers face other obstacles: ageing fishermen and vessels, mysterious changes in cetacean behaviour possibly linked to climate change, and a stubborn refusal among Japanese people to eat enough whale meat to make killing them a profitable venture. [...] While Japan skirted the IWC ban by conducting limited "scientific" hunts in the Antarctic, it had long argued that only a return to commercial whaling would guarantee a stable supply of affordable meat and ignite a revival in consumption. "But all the evidence points in the opposite direction," says Patrick Ramage, senior director for outreach and programme collaboration at the International Fund for Animal Welfare. "Whether pursued on the high seas under the pretext of science or in coastal waters in pursuit of profit, Japan's commercial whaling is an economic loser, kept afloat only by government subsidies."
