May I eat human vegetables? May I steam one like a lobster?
Yes. Though I would not recommend it for health reasons, and chances are you would be reviled as a cannibal.
This is assuming that Orcas are capable of the inane anthropomorphic empathy some of our kind possesses for lesser lifeforms.
Ok. This needs to be unpacked.
1) They are social creatures. Empathy is the backbone of complex social interactions, and orca grieve for their dead. There is nothing to indicate that they dont feel empathy in some form. Now, it may be the case they they cannot expand that to other species. It is certainly possible that their cognitive capacity is insufficient and too child-like to be able to extend their empathy that far. However considering how dolphins in general interact with people who they have accepted into their social group, that possibility seems remote.
2) There is absolutely no difference inherently between a human and any other intelligence, save perhaps for the magnitude of intelligence and emphasis on specific aspects of cognition. There is in fact no such thing as a lesser life form, because that implies some sort of scala natura. The 14th century called, it wants its conception of nature back. Animals with sufficient cognitive capacity feel the same emotions we do. So there is no reason to call empathy inane. It is perfectly valid, unless you want to continue in your categorical fallacy. If you want to do that, I can just sit back here with some popcorn and watch you impale yourself through the rectum with your own stupidity.
Agreed, Orcas can't even trade with human civilization due to a lack of thumbs, so we cannot even trade with them humanely derived food.
No trade is required. Different groups of orca specialize on different food items. Some pods on seals, others on fish etc, depending on what is locally available and what other pods are eating (two different pods in the same area specialize on different prey to avoid competition). Eating of other fully sapient beings is generally rare.
Oh and um... you know, there is nothing saying we cannot just... you know, give the affected pods food should we eventually learn to speak orca and convince them that eating other dolphins is probably wrong. We could also stand to stop over-fishing so that they can more easily merge pods. I figure if things progress that far, we should be able to deal with that issue.
Have moral hazard you want to deal with? Find a fucking solution. The solution to moral hazard is not to complain about how hard it might be to deal with it. You be an adult, and you deal with it.
It doesn't excuse humanity, but, how can I complain in my comfortable home typing away using electricity?
Wait, so because you live a cushy life, you have no right to say "hey, maybe it would be a good idea if we stop raping the oceans" and instead must simply assent to every fucked up things people do?
I am sitting here using electricity. Electricity that is 100% renewable. I also restrict my fish intake to sustainably farmed fish (read: lower trophic level freshwater fish that are not fed other fish) and well-regulated alaskan salmon. Other meat intake is limited to a fraction of the typical american diet. I drive a fuel efficient car.
With even that small amount of effort, I have managed to mitigate both my carbon footprint, and my impact on the world's oceans. It is not even the limit of the various things I do.
What you are is a contemptuous lazy moral coward, worthy of nothing but contempt.
Slavery is okay as long as non-violent resistance is not punished, as that is the true marker of freedom.
Go fuck yourself, you slavery-apologist sack of shit.
