The train leaves the platform. After sitting silently for a while, a woman looks up from her newspaper and says to her friend, "It says here that 90% of all large fishes have disappeared from the world's oceans in the past half century because of industrial fishing."
Her friend looks up in dismay.
The woman continues. "Only 10% of the whole world's tuna, swordfish, marlin, cod, halibut, skates and flounder are left. In the whole world! That's it—I'm never eating tuna again."
"Are you serious?" Her friend says. "I'm going to eat as much as I can before it's all gone."
