To Till and to Tend

A common line one hears in religious circles is “God works in mysterious ways.”  Is it possible to conclude that when God realized people were going to love eating large, long-lived fishes (which were, after all, created on the 5^th day) to the point of oblivion, God actually made us humans pollute the waters so that eating these fish would be toxic to our bodies and we would moderate our consumption?

Probably not. While the notion may be laughable, it does shed light onto the occasional irony that is human induced pollution. While more often pollution and climate change work to endanger and eliminate species from our planet, in this case could our destructiveness save several? 

Some background information: Half of the planet’s atmospheric mercury is human generated, most to produce power that fuels our lives.  As the hunger for sushi has grown and globalization aids all fish exports, the Food and Agriculture Organization (FAO) estimates that over 70% of the world’s fish species are either fully exploited or depleted. 

The general public is only beginning to learn what pregnant and breastfeeding women (and some others) have known for years: many fishes have mercury, and it is dangerous to eat too much as mercury can get passed along through the placenta and breastmilk. 

Though children and fetuses are at the highest risk, because their brains and nervous system are still forming, it has only recently been published that the quantities of mercury in the fishes we eat can be harmful to adults.  The Environmental Defense Fund has a useful report on mercury, from which I excerpt:

“Mercury exposure can also harm adults. Symptoms can include numbness, burning or tingling of the extremities (lips, fingers, toes); fatigue; weakness; irritability; shyness; loss of memory and coordination; tremors; and changes in hearing and blurred vision. Extremely high mercury levels can permanently damage an adult’s brain and kidneys, or even lead to circulatory failure.”

Last January, the New York Times broke the story, “High Levels of Mercury Found in Tuna Sushi,” inspired talk, blog posts and more news reports.   Maybe people will be motivated to care for their bodies and eat less mercury heavy, over-fished fish?  Maybe, just maybe, one day our fisheries will be healthy, and eating the fish from them will be healthier, too.

My favorite: Monterey Bay Aquarium’s Seafood Watch – a complete guide of all fishes and their health/environmental implications
Environmental Defense Fund’s Guide of “How many meals (of which fish) are safe to eat each month”
Hilarious analysis of the news threads from Newsweek, “Would You Like Mercury With Your Sushi?”
