For a dose of home-grown common sense, I'll share this.
My wife likes the elephants, as well as other animals.
It makes her sad when she sees that someone stepped on a snail.
She won't go to the circus because of how they treat the animals (especially the elephants).
She won't watch the part of nature shows where the lion eats the gazelle.
I asked her if she though that banning the sale and trade of mammoth ivory would help anything.
She said "Aren't mammoths already extinct? And they aren't elephants anyway, so no."
You know what, I'm with her on this one.
PS: she ain't just agreeing with me for the heck of it either; she has no problem telling me when she thinks I'm an idiot.
