 This is Scientific American 60 Second Science, I'm Steve Mirsky, got a minute?

 
Tens of millions of sharks are killed for their fins1 each year. It's not just a tragic2 abuse of the animals,  It's bad business.
 
"They're basically swimming dollar signs, whether you're trying to kill them for their meat or their fins or you're interested in looking at them for ecotourism." That's Austin Gallagher, a doctoral student at the University of Miami. I spoke3 with him on February 26th.
 
"We did some calculations and the results were remarkable4. We determined5 that the average shark was worth about $200,000 over the course of its life. And when you compare it to finning6 that animal--a one-time extractive use--seeing it for diving is worth about 40 percent more."
 
Gallagher and his doctoral advisor7 Neil Hammerschlag published the study last year in Current Issues in Tourism. 
 
"Since this paper came out, I got an e-mail from somebody in Bali just a weeks ago saying, `We're using your paper to stop illegal harvest of thresher sharks in Bali at a local dive community.'"
 
Thanks for the minute for Scientific American 60 Second Science, I'm Steve Mirsky.
