Environmental justice or eco-terrorism? Depending on your thoughts about the whaling industry — and the confrontational efforts to stop the industry — your view of the hunters and eco-activists featured in Whale Wars will differ greatly.

Animal Planet’s Whale Wars features the sometimes-dangerous clashes between the Japanese whaling program and the Sea Shepherd Conservation Society — and the upcoming second season promises to be even more action-packed than the first!

"Collisions at sea, harrowing nautical maneuvers, a near-death experience in an ice field and more aggressive Japanese defenses against the Sea Shepherds — including the use of Long Range Acoustical Devices (LRADs), sonic devices that cause intense pain and could cause permanent hearing damage" are among the crazy events you'll see this season. Below's a preview:

How did whales take center stage in these environmental wars? Back in 1986, Japan agreed to the International Whaling Commission's moratorium on commercial whaling — but then started what the country calls a scientific program to assess whale stocks — a program Sea Shepherds argue is illegal commercial whaling.

Find out more about the controversy, and read an interview with Paul Watson, founder of Sea Shepherds. Then tune in to Animal Planet this Friday, June 5 at 9 p.m. to catch the season premier of Whale Wars.
