We're asking a question here.
Why is it if the shark fin industry is so vast that we see so few images of the industry in action?
A Google image search for shark finning reveals 98,500 results.
A Google image search for Bigfoot? 2,380,000 results.
If you asked folks on the street if they believed in Bigfoot you'll probably get at least a 98% awareness of the Bigfoot myth.
And shark finning?
Food for thought.
