Its a hard situation.
On one hand you have certain Chinese people/families who make geniune products from certain animals, and have been doing so for centuries. I don't believe that is wrong.
But on the other hand you have the certian Chinese people (or other cultures) who are doing it because they know "stupid" and easily led people will believe their product does something it does not.
It wasn't until humans MASSIVE population explosion that these natural, centuries old practices came under fire. When the earth had less people, there was more of a balance. But more and more and more people see they can make a fast buck cheap and they start depleting natural sources of snakes, rhinos etc.
