Fish Are Eating Lots of Plastic (washingtonpost.com) 149

Matthew Savoca, writing for the Washington Post: As you bite down into a delicious piece of fish, you probably don't think about what the fish itself ate -- but perhaps you should. More than 50 species of fish have been found to consume plastic trash at sea (alternative source - a little old). This is bad news, not only for fish but potentially also for humans who rely on fish for sustenance. Fish don't usually die as a direct result of feeding on the enormous quantities of plastic trash floating in the oceans. But that doesn't mean it's not harmful for them. Some negative effects that scientists have discovered when fish consume plastic include reduced activity rates and weakened schooling behavior, as well as compromised liver function. Most distressingly for people, toxic compounds that are associated with plastic transfer to and bioaccumulate in fish tissues. This is troubling because these substances could further bioaccumulate in people who consume fish that have eaten plastic. Numerous species sold for human consumption, including mackerel, striped bass and Pacific oysters, have been found with these toxic plastics in their stomachs. So why are fish eating plastic? According to studies cited in the report, plastic debris may smell attractive to marine organisms.

    I believe it. My cat loves to lick those plastic shopping bags from the grocery. According to the interwebz he is not alone, its because they taste like meat to some cats. Fortunately he has not yet tried to eat any of them.

    The next big question that it raises is whether plastic-derived contaminants can be transferred from plastic-eating fish to fish-eating humans.

    If eating the plastic doesn't harm the fish, and causes no harm to the people that eat the fish, then why is this in the "health and science" section of the Washington Post? I mean, this is neat and all but is this something someone other than a biologist might find interesting?

    I think that perhaps they should have held on to this until they actually figured out if the plastic eating habits actually do harm. But then again, if they saw nothing so far then haven't they already proven

      Actually, eating plastic does harm the fish.

      Some negative effects that scientists have discovered when fish consume plastic include reduced activity rates and weakened schooling behavior, as well as compromised liver function.

      Thus your question is based on a false assumption.

    • There's also the issue of biomagnification--bioaccumulation moving up the food chain.

      Small fish consume small amounts of plastic.
      Larger fish consume many small fish over time, consuming (and accumulating) larger and larger amounts of plastic.
      Higher-level predators--Dolphins, polar bears, whales, people--eat these larger fish, accumulating even more plastic.

      The small fish may never consume enough plastic for it to be a huge deal, but it might be a really big deal for the polar bear.

        What we have here is a half of a study. I'm not sure if this is a call to action, as in telling people to stop using plastic or something, or a fundraising effort of the "OMG, pollution!" kind.

      As others have already pointed out, plastic does harm the fish, even if it doesn't kill them outright. Not only does a lot of the plastic come as very small fragments, which may well pass into the bloodstream, but they also give off harmful chemicals. Since much of the plastic debris in the ocean has been floating around for decades, part of it will contain chemicals that are now banned. The problem of accumulation is exacerbated by the fact that many of the fish we eat, have eaten smaller, that have eaten

    of 30 years of outsourcing, automation and cheap work visas this is the least of my worries. That's sort of the problem. It's hard to get worked up about problems like this when 60-80% of us live paycheck to paycheck (depending on which study you want to believe).

    If you're an environmentalist then you've got to take care of the economy first. Otherwise the vast majority of people will ignore it in favor of more pressing concerns (rent, food, etc). Does that make the working class short sighted? You damn well bet it does. It's hard not being short sighted when you live paycheck to paycheck.
    • That's the honest short-term view most people feel - including myself. When ocean life starts to struggle to survive in the plastic soup we're stirring up for them, however, all so we can have water bottles and other throwaway junk to make life faster and easier so we can screw around more, it'll become everyone's short-term food problem as prices skyrocket and push your budget over the edge.

That bottle of soda, that 6 pack of beer and that microwavable lunch are the bare minimum needed to see them through the day.

      Low wages and precarious employment are a very pressing issue indeed.

      However, the main issue with environmental concerns is that although they're caused by consumerism, e.g. millions of tonnes of toxic plastics from food packaging dumped into the ocean, the solutions aren't more consumerism. Ordinary people can't shop their way out of environmental pollution. The only way to reduce pollution in the face of consumerism is through government regulation, i.e. preventing corporations from "externalising" costs, i.e. not taking responsibility for the pollution they cause.

      Governments can't require that other countries abide by their own environmental laws but they can refuse entry or place substantial import tariffs on goods that have a heavy environmental impact.

      It'd work if the corporations responsible for the environmental damage weren't in control of our governments and environmental agencies (AKA regulatory capture).

      We try, but the anti-environmentalists keep trying harder to fuck it up. Most environmentalists favor universal health care, strong public support for education and job training, as well as a social safety net. The so-called libertarians keep trying to fuck up both the environment, along with any hope of stability and autonomy for ordinary workers.

      60-80% of residents of the world's wealthiest nation live paycheck to paycheck regardless of the size of their paycheck because all they know how to do is consume ever more. That's also the reason why there's so much plastic for fish to eat. You can solve both problems the same way.

The trouble is that means sometimes people who don't do any work get to live OK. And that really, really rankles about 20% of the population. We need them to get over it and fast or we're heading for a dark age.

People love to eat predatory fish and they have the highest mercury concentrations. Some from natural sources but the majority is from coal power.

  • Think about it this way. Several fish are on their way to extinction due to being over-fished. If we were no long able to consume many of these fish, if they find a way to thrive, they will return to previous population levels in the ocean and we won't be predators any longer which give other species opportunities. At some point either the plastic will hopefully break down and be consumed or our species will die off at which point fish will out last us. If they don't thrive, so long and thanks for all t
