Adventure journalist Peter Heller took a voyage he never expected: crusader to protect ocean life. He accepted the invitation to crew on board Sea Shepherd’s ship Farley Mowat for the 2005-2006 Antarctic campaign. He chronicled this two-month journey in his book “The Whale Warriors: The Battle at the Bottom of the World to Save the Planet’s Largest Mammals”.

"I’ve always been drawn to the ocean (02) but the experience kindled a fire in me to protect marine mammals," Heller said in an interview. “The ocean is so much a part of the web of life. If the ocean dies, we die too."

In the November 2006 issue of Science, Heller said, a report by an international team of scientists studying data over 58 years declared that if current trends of fishing and pollution continue, every fishery across the planet will be totally destroyed by 2048. The oceans as an ecosystem would completely collapse.

"Jacques Cousteau said 30 years ago that the oceans were dying in our lifetime," Heller noted. "Half the coral reef is dead or dying. People don’t pay attention because they’re under the surface." “Marine algae create the majority of oxygen in our atmosphere. If the oceans die, it could cause great destruction (01). It’s in our own self-interest to take action right now," Heller said.
