W: Hi, John. How are things going?
M: Oh, hi. Fine. How about you?
W: You can probably tell just by looking at me. I’m really busy. Well, what are you reading?
M: A very interesting article. My biology professor assigned it. I thought I would just look it through, but I got really involved in it. It’s about endangered species.
W: That sounds pretty interesting. I’m getting frustrated with the two research papers I’m struggling with.
M: Oh?
W: Besides, they are both due on the same day. It’s unbelievable.
M: That’s tough.
W: I’ll get through it. So what’s this you are reading?
M: Well, it’s basically about the choices conservationists are faced with. You know, these days funding is so hard to come by.
W: Wait a minute. Is the focus on biology or economics?
M: Both. Conservationists don’t have enough funding to save every endangered species in the world, so they have to decide, based on what would be lost if a species became extinct.
W: Can you give me an example of what you mean?
M: Take for instance, two animals, the spotted awl and the tailed toad. The article says the toad is unique. It has no relatives. But there are a lot of varieties of awls.
W: So, if that toad became extinct, we’d lose an important link in the chain of evolution, right?
M: Exactly. But that isn’t so for the awl. So for conservationist, it might be a clear choice of which animal to save.
