I know it's a meme, but is anyone actually sad for the fish? I thought we were terrified about what was happening to our food. If someone autopsied a downed cow and a bunch of toxic plastic shit spilled from their stomachs, we aren't thinking "poor cow ate all that plastic and died." We're worried about our food supply.
People here are talking about fishes as our food source but what about fishes as a food source for other aquatic life? Or other animals that feed on those marine life? The effects can be far reaching. So the implication of a fish dying from plastic is a bit more complicated than what OP's making it out to be
Any fish that dies from plastic is dying from a method that isn't me eating it. Also, there's lots of fish I don't eat that I'm not cool with dying to plastic. I really like the ocean plants that make all the oxygen I breath too.
It's weird. I don't like most fish, but I really don't have an ethical problem in general with eating fish as long as they were harvested sustainably. Unfortunately, most of the saltwater fish I have enjoyed over the years- shark and swordfish steak, cod, tuna- are not harvested sustainably, so I don't eat them. That pretty much leaves me with farmed trout and catfish, the only two other fish I like. And I just don't feel like it's the same as eating a cow or a chicken. Maybe I don't have any actual scientific basis to go on, but fish are just so different from us and so much more primitive that it just doesn't bother me.
