A study shows that one shark is worth $ 179.000 (per year) or US$1.9 million over its lifetime for Tourism only. The same shark dead sold for consumption $ 108. Check on this video http://www.pewenvironment.org/news-room/video-library/million-dollar-reef-sharks-85899359403
Each year over 100 million sharks are getting killed for a deli called "Shark Fin Soup". This practice is already threatening the stability of the marine ecosystem. Phytoplankton contributes up to 85 percent of the oxygen in Earth’s atmosphere.So please stop eating shark fin soup. It just doesen't make any sense!
If you care and would like to do something, you may talk to restaurant owners to remove shark dishes from their menu. Or you take some time and write a mail to the editor, when sharks dominate the headlines as monsters. If you want to share the whole thing or parts of it on twitter or facebook, please do so.
