Fish, mercury, and not freaking out

One of my main goals for this pregnancy has been not to freak out. In general I'm a slightly anxious person--calibrated so that my system tends to operate with a bit more adrenaline than other people's--and I'm also someone who likes to be informed, educated, and in control. But I've felt that many of these tendencies could be counterproductive for me as a pregnant person. I haven't wanted to become an expert on pregnancy. I've been reading midwifery books, but really nothing else--not What to Expect While You're Expecting, not the four million pregnancy websites, not even the very interesting books out there about third wave motherhood (although I might get to those). It's Biffle's job to do the reading--he has a site that he looks at once a week to tell me what's happening gestationally, and if I have specific questions ("Can I take Tums?" "Is it normal that I'm feeling a shooting pain in my side?"), he looks them up and finds the answers (yes to both of the sample questions).

I knew that there were concerns about mercury in fish and that I was supposed to avoid certain fish, but I didn't know the details. In my own head I figured any flaky white fish was probably fine, and so--although I don't eat fish often--I have had fish every now and then when we've gone out to eat. For some reason, this morning I wanted details, so I had Biffle do an internet search about mercury in fish, and how this relates to pregnancy. He found a ton of information. It turns out there are a lot of fish pregnant people are supposed to avoid altogether, including king mackerel (repulsive, so I have not eaten it), shark (I think I may oppose shark-eating on political grounds), and tilefish.

I ate tilefish a few weeks ago, when Catherine and James were in town visiting. Tilefish is a flaky white fish--and it was quite delicious--and now it turns out that pregnant people aren't supposed to eat it at all because of the high levels of mercury in the fish, mercury that can affect fetal brain and nervous system development. (It also turns out that two of the other fish I've eaten while pregnant--grouper and halibut--are on the "eat very rarely" list).

To my credit, I didn't freak out, although I did make Biffle look around longer on the internet until he found an FDA site that said that eating tilefish once while pregnant probably wasn't a crisis situation.

But here's my question: what the fuck are we doing to our planet? The run-off from our coal-fired power plants is affecting marine life so significantly that there is a solid consensus that certain fish are now too toxic for pregnant people to eat. This shouldn't be just an interesting fact for a pregnant person to tuck away--this is a sign of very, very bad things to come. Although I don't want to freak out about this on a personal level, I do think a bit more cultural freaking out would be appropriate.
