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


 
Tens of millions of sharks are killed for their fins 1 each year. It's not just a tragic 2 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 spoke 3 with him on February 26th.
 
"We did some calculations and the results were remarkable 4. We determined 5 that the average shark was worth about $200,000 over the course of its life. And when you compare it to finning 6 that animal--a one-time extractive use--seeing it for diving is worth about 40 percent more."
 
Gallagher and his doctoral advisor 7 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.
