From what I have heard, you are correct. Last I heard, they do hold a lot of toxins in their blubber alone.Mercury probably being one of them; just like sharks. It's kind of ironic, isn't it? We contaminate the sea and then that affects the wild-life in it and then we kill them and eat them and get even more contaminated ourselves.
Good, ol' nature's revenge really!

If cows were to desapear too, perhaps would it be time to finally create synthetic meat, or whatever it can be, without being forced to kill a living creature (except plants of course. Cut all those green things and trees! There's too much sssspiders there...beuuuuh

). No, seriously, wouldn't it be better (well, at least for our mind and/or soul)?
And amough all the suggestions of this topic (because they are cute, because they are almost instinct, because it's not good meat,...), I'm surprise not to see the most important one (well I mean, for me): because they just are living creatures, like us humans...
So...Animals shouldn't eat other animals either? Humans are animals and we're omnivorous, which, of course, means we eat both vegetables
and meat. We
need meant. However, we do need to be much, much more intelligent, responsible, respectful, cautious, wise, and everything like that as we go about it, especially if we're going to claim that we are superior and more intelligent.
Also, if humans stopped eating meat, we'd need much more bigger farms which would mean more habitat destruction and, thusly, more animal death and more animals going on the endangered list or, worst yet, going completely and utterly extinct.
Not to mention that, on big farms, big machinery is used to harvest the crops and quess what happens then? Field animals, like mice, rats, snakes, rabbits, and the like, get chopped up. And also they don't get eaten either. At least when we kill animals for food, we do use at least
some of it. Or, more like it, we have the
intention as I'm sure, in North America anyway, a lot of meat is brought and then kept in the freezer for 10+ years and becomes horribly freezer burnt, but nevertheless.
