In reply to Mokkel:
The objection to whaling is more about the large scale commercial operations, and so-called aboriginal whaling that is done as a way of life, for essentials, is regarded as OK.
Like a smallholder hunting and killing their own food, as they have a requirement / dependency on it.
Japan is at the forefront of wanting to restart commercial whaling using massive factory ships that can deal with 100s of whales at a time. And that is the sort of operation that drove some species of whale to the brink of extinction, purely from hunting.
Now, whales are being driven to the brink of extinction by other man-made problems, such as polluting (and poisoning) their food chain, over fishing their food chain, climate change causing food sources to disapear or re-locate (ie get extinct in some areas, and grow in other areas) and so on.
We see the same problems on fish stocks which are a) hammered by huge commercial fishing fleets, and b) have their food source migrate to cooler waters (ie further north in the northern hemisphere, and further south in the southern hemisphere) and so fish populations are struggling more with overfishing and climate change than us humans are, because we can adapt, and have massive resources, and they cannot. Move, or die
And sea bird populations are finding that their traditional nesting places, that rely on a supply of food at the right time of ear, in the right place, are starting to be in the wrong place. Of course, they don't know that, they just die, and nore southern, or northern, nesting sites tend to fair better, and get more populous.
But us humans are putting huge pressures on the ecology of the sea, and changing things purely by carelessness, or lack of consideration of the consequnces.
And some people want to hunt theese food stocks to extinction purely to maintain a commercail industry that no longer has any real reason for existing, other than commercial pressure.
