Tensof millions of sharks are killed for their fins each year. It's not just a tragic abuse to the animals, it's a bad business.They’re basically swimming dollar signs,whether you’re trying to kill them. Fortheir meat or their fins or you’re interested inlooking at them for ecotourism. That's AG, a doctoral student at the University of Ma, I spoke with him onFebruary 26. We did some calculations, and the results were remarkable. Wedetermined that the average shark was worth about 200,000 dollars over thecourse of its life. And when you compare it to finning that animal a-one-time, extractive use, seeing it for diving is worth about 40% more. G and his doctral advisor N H published the study lastyear in current issues in tourism. Since thispaper came out, I got an email from somebody in B just weeks ago, saying we’re using your paper to stopillegal harvest of thresher sharks in Bat a local community. extractive:采掘,
