For all the talk about how Sea Shepherd endangers life and limb of whalers, sealers, poachers, and even supposedly its own crew, the fact is that in more than 37 years of operations not a single Sea Shepherd crewmember has been killed or seriously injured. This covers hundreds of voyages and confrontations on the high seas in some of the most remote and hostile waters in the world. Nor has any Sea Shepherd action ever caused a single injury, let alone a fatality to those who Sea Shepherd obstructs, harasses, and prevents from continuing their illegal acts of exploitation.
One major Sea Shepherd critic is SeaWorld, whose enslavement of orca whales and dolphins has generated hundreds of millions of dollars in profits. And a SeaWorld captive - Tilikum - has killed three human beings.
I can't really blame Tilikum. If I were taken from the ocean and plopped into a concrete prison cell for four decades I would be inclined to get a mite angry also.
No reasonable person would walk unescorted across the exercise yard of a maximum-security prison, and it is irresponsible to expect a frail human being to turn his or her back on a stressed-out, angry, captive orca - the most formidable predator on the planet.
