Season's greetings from Truthdig! We bring you this message by our brilliant Mr. Fish, winner of the editorial cartooning award from the Society of Professional Journalists for the second year in a row. Please check out our donation page and help support the work of Fish and Truthdig's many other talented authors and contributors.

Take a look at this season's special holiday offerings in the Truthdig Bazaar, including our first book based on Chris Hedges' original Truthdig columns; signed prints, custom-made cartoon T-shirts and mugs featuring the work of Mr. Fish; and autographed book collections from Truthdig Editor Robert Scheer.
Keep on digging!
So, naturally, Republicans are furious. But before I get to the politics, let’s talk about what a good thing the E.P.A. just did.
As far as I can tell, even opponents of environmental regulation admit that mercury is nasty stuff. It’s a potent neurotoxicant: the expression “mad as a hatter” emerged in the 19th century because hat makers of the time treated fur with mercury compounds, and often suffered nerve and mental damage as a result.
Hat makers no longer use mercury (and who wears hats these days?), but a lot of mercury gets into the atmosphere from old coal-burning power plants that lack modern pollution controls. From there it gets into the water, where microbes turn it into methylmercury, which builds up in fish. And what happens then? The E.P.A. explains: “Methylmercury exposure is a particular concern for women of childbearing age, unborn babies and young children, because studies have linked high levels of methylmercury to damage to the developing nervous system, which can impair children’s ability to think and learn.”
That sort of sounds like something we should regulate, doesn’t it?
The new rules would also have the effect of reducing fine particle pollution, which is a known source of many health problems, from asthma to heart attacks. In fact, the benefits of reduced fine particle pollution account for most of the quantifiable gains from the new rules. The key word here is “quantifiable”: E.P.A.’s cost-benefit analysis only considers one benefit of mercury regulation, the reduced loss in future wages for children whose I.Q.’s are damaged by eating fish caught by freshwater anglers. There are without doubt many other benefits to cutting mercury emissions, but at this point the agency doesn’t know how to put a dollar figure on those benefits.
Even so, the payoff to the new rules is huge: up to $90 billion a year in benefits compared with around $10 billion a year of costs in the form of slightly higher electricity prices. This is, as David Roberts of Grist says, a very big deal.
And it’s a deal Republicans very much want to kill.
With everything else that has been going on in U.S. politics recently, the G.O.P.’s radical anti-environmental turn hasn’t gotten the attention it deserves. But something remarkable has happened on this front. Only a few years ago, it seemed possible to be both a Republican in good standing and a serious environmentalist; during the 2008 campaign John McCain warned of the dangers of global warming and proposed a cap-and-trade system for carbon emissions. Today, however, the party line is that we must not only avoid any new environmental regulations but roll back the protection we already have.
And I’m not exaggerating: during the fight over the debt ceiling, Republicans tried to attach riders that, as Time magazine put it, would essentially have blocked the E.P.A. and the Interior Department from doing their jobs.
Oh, by the way, you may have heard reports to the effect that Jon Huntsman is different. And he did indeed once say: “Conservation is conservative. I’m not ashamed to be a conservationist.” Never mind: he, too, has been assimilated by the anti-environmental Borg, denouncing the E.P.A.’s “regulatory reign of terror,” and predicting that the new rules will cause blackouts by next summer, which would be a neat trick considering that the rules won’t even have taken effect yet.
More generally, whenever you hear dire predictions about the effects of pollution regulation, you should know that special interests always make such predictions, and are always wrong. For example, power companies claimed that rules on acid rain would disrupt electricity supply and lead to soaring rates; none of that happened, and the acid rain program has become a shining example of how environmentalism and economic growth can go hand in hand.
But again, never mind: mindless opposition to “job killing” regulations is now part of what it means to be a Republican. And I have to admit that this puts something of a damper on my mood: the E.P.A. has just done a very good thing, but if a Republican — any Republican — wins next year’s election, he or she will surely try to undo this good work.
Still, for now at least, those who care about the health of their fellow citizens, and especially of the nation’s children, have something to celebrate.
