    Two Australians, Mack and Jill, are camping on Kangaroo Island.
M: Look! There's a koala hugging a tree. They're really so cute. Jill, why are you crying?
J: The government's planning on killing them because they may starve to death soon.
M: What a stupid idea! They should try saving them instead.
J: I agree. Let's start a campaign to save them. If we can find 5,000 people to each take one home. The
   problem will be solved.
M: That's a good idea. You know, there're about 18 million people in Australia. Five thousand is only 0.027
   percent of the population.
J: Let's do it then.
M: Killing as a solution to a problem is just not right.
J: You can say that again.
