Amazon selling Shark products.

I have recently become aware that Amazon are selling several so called health products made from shark cartilage. Although Project Aware has done a fantastic job at CITES, all the while there is a demand for these items, illegal finning will continue. I have written to Amazon stating my disgust that a well respected multi national organisation like themselves are condoning the barbaric practice of shark finning by selling these evil products. As yet I have had no reply (surprise surprise!!). One person is easy for them to ignore which is why I'm asking everyone who reads this to also contact Amazon and voice their disapproval of such an abhorrent and vile trade. Please help. Together we CAN make a difference.
