They fight whaling all over the world. From Norway's Arctic whaling to Japan's antartic whaling. They are active the entire year, not just for the Antarctic whaling season. It just so happens the Anarctic whaling season is between December and February, and that is what Whale Wars is centered on. For the time period the Japanese are whaling, they kill far more whales in that time than any other country do in a year.
And which country do you mean? You do realise Sea Shephard has Canadian, British, American, New Zealand, Australian, Japanese and other nationalities as members right?
American whaling is from small Alaskan indigenous people, and they take around 50 Whales per year. Where as Japan's quota is over 1000 in the space of a few months. Pretty sure it's obvious why they are tackling Japanese whaling during the December-Feb Months. The numbers are obliterating the oceans. Canadian Whaling is in small groups by Inuit tribes as far as I am aware.
Also, commercial whaling is against International Law. Near all of the Whaling is taking place in International waters also, so they aren't really tackling whaling IN a specific country, more stopping a country from breaking maritime law. The Japanese whalers hide behind a lie, saying they're killing for research. Then go on to sell the meat and make millions. It's disgusting.
