Sharks play a very important role in the natural Eco-systems in the ocean. The products being sold on eBay are coming directly from the inhumane killing of Sharks. The shark finning industry is slowly killing millions of sharks every year. This disrupts the natural food-chain in the ocean and some species have declined dramatically with no time to recover, leaving their numbers to dwindle. Allowing people to sell these products is purely encouraging them to continue hunting sharks for their fins and other by-products.
eBay need to make a conscious decision not to allow sales of shark related products. They should set a better example for the rest of the world that they do care about the environment and the animals being affected by these senseless killings. eBay, it's time to step up and make a change. Please don't allow these majestic animals of the ocean be exploited on your site for money. Your customers demand that you prohibit these items and stand up for what is right.
Here is an example of some of the products being sold that should be removed immediately: http://www.ebay.com/sch/i.html?_nkw=shark+cartilage+&_cqr=true&_nkwusc=shark+cartilege&_rdc=1
