Shark attacks are no laughing matter, and close shark encounters can strike fear into the heart of any beachgoer.
Sadly, more than 100 million sharks are killed every year. There have been recent bans on shark finning, the practice of cutting off the fin of an animal while it's still alive, in an attempt to curb growing demand. Unfortunately, the outlook is dire. Visit the Humane Society International to find out how you can help stop shark finning.
