Take a COOL Guess – the Fun Quiz on Clean Energy. Today’s Topic: Environmental Toxins

Relevance:  Most of the effects of the actions we take today – good or bad — have repercussions for extremely long periods of time. This reminds us of what Thomas Jefferson famously said, “It is incumbent upon every generation to pay its own debts as it goes.”  Not to moralize, but I think he nailed something there.
