What purpose do whales serve? other than they are kinda cool looking animals, and smart but Free Willy was an annoying movie... Do whales help the environment? I'd imagine they eat a ton of fishies in an area that's already overfished...

Would killing them off adversely affect sea environments? Probably, but I don't think that the serve a purpose any more than any other animal (humans included) serves a purpose.

I do agree that eliminating a species will likely affect an ecosystem. I don't think that nature balances itself, nor do I think that all species "have a place". (Other than in the sense that species interact with one another and eliminating one will likely affect another).
From a biological perspective, humans are just one more (particularly powerful) selective force to which other animals must adapt.
From a human perspective, we should probably be careful not to wipe out other species. Eliminating a species may have an adverse affect on us.
