Great cause, Sawyer, and a very mature opinion on a subject that more people should be aware of. I tried to find a way to sign your petition but could not, so wanted to pass along this website that I found that gathers petitions on the halting of shark finning and thought you might want to sign them and also maybe create and post your own.
And Change.org is great for creating those petitions.
Best of luck and keep at it.
Clear eyes, full hearts, can't lose.
