“This ironic cartoon by Sidney Harris recalls a time of the great mercury-in-tuna scare. Certainly, mercury contamination can be a deadly problem, but I think this threat pales in comparison with other environmental challenges we face for a growing population, such as how to generate more energy, how to make more drinkable water, and how to grow more food that people want to eat, all in a sustainable manner.” – Richard N. Zare (Stanford University)
