Mercury — the stuff used
in thermometers — is poisonous. It evaporates into
the air around mines and factories, builds up in rain
water, and eventually reaches the ocean floor. There,
bottom fish eat it, and it gradually accumulates in big
fish higher up the food chain.
One + Two Design, Inc. in Portland, Oregon contracted with
Harvest Moon Studio to create “Watch What You Eat!,” an
animated computer program. Cartoon fish guide visitors through the process of mercury build-up and how to monitor their consumption of swordfish, tuna fish and others. A 200-pound
tuna fish, for example, may have enough mercury to warrant
limiting young children to less than one can per week. |
