Statistically Speaking: Diversity in Our Diet

by Bill Chameides

Because we’re rarely more than a short drive away from a drive-thru, Americans might not even be aware of the increasing trend toward monoculture in our managed ecosystems. (See related video.) It's a worrisome trend. Now here’s something else to nibble on: the loss of diversity in the plants we eat.

Like many other Americans I was sitting at a table last week eating horseradish to remind me of the bitterness of slavery. My horseradish came out of a jar. But I began to wonder, what does the stuff actually look like?

U.S. corn ethanol production has been on the rise. That’s good for our country’s carbon footprint, right? A new study suggests not.

Some argue that more carbon dioxide is a “good thing.” I guess they just can’t get their minds around the whole climate change thing. OK, but what about ocean acidification? If you like seafood, ocean acidification is definitely not a good thing.

Regardless of your stance on global warming, you should be worried about a related problem: ocean acidification. You don’t need a climate model to know this is serious, especially if you like -- or depend on -- seafood. Two new papers explore just how serious.

For decades, big companies have been consuming others until only a few are left. This Pac Man-like game has been especially true of agriculture where a handful of large corporations control almost every aspect of our food production.

Many of us love bluefin tuna – think sushi and sashimi – a fish so in demand that just one can fetch upwards of $10,000. But there are reasons to think twice about eating it. Mercury contamination is one. Another is declining numbers. For 40 years, despite catch regulations, Atlantic bluefin tuna populations have declined precipitously. Some estimates show western Atlantic bluefin tuna down by 90 percent from preindustrial levels. Overfishing may have already pushed bluefin beyond the brink of return. What’s gone wrong?

by Bill Chameides
Oct 29, 2008
filed under: , , , , , , , ,

Mercury poisoning has a long history. The phrase "mad as a hatter" (circa 1830s) derives from the slurred speech, tremors and other neurological symptoms displayed by the day's hatmakers – maladies caused by long-term exposure to mercury used in hat-making. Today, the highly toxic metal continues to plague us, and new studies indicate even very low doses of mercury can be risky. But there's at least one way we can safeguard against it – remember, you are what you eat.

Who doesn’t want to be green? But beware of automobile ads claiming environmental benefits from home-grown ethanol. Almost all U.S. ethanol comes from corn and, as a fuel, corn just isn’t as “amaizing” as they say.
