Animal Planet has a new show airing Fridays @ 9pm called Whale Wars about a conservation group (Sea Shepherd) doing everything it can to stop Japanese fishermen from whaling in an Australian wildlife refuge in the Arctic. The conservationists are more like eco-terrorists, buy you have to sympathize with them. Each person on the conservation ship (the Steve Irwin) is willing to give their life to save the life of a whale.
I recommend watching at least the first episode in this series. You'll want to keep watching whether you're pro- or anti-whaling. If you're a Comcast customer, these episodes are available On Demand.
