Blue sharks are among the most threatened species of sharks in the world. Trade in shark fins and overfishing have caused them to decline so rapidly that scientists worry about their future recovery.
It takes a lot of work to maintain a gene pool: Some female sharks use sperm from multiple males to father a single litter. That makes her pups half-siblings, even though they're born at the same time.
Also.... stumbled upon this today and was lieterally sick to my stomach to see how many resturaunts in VA alone serve shark fin soup! And SO many are with in a 10 mile radius of me! How do you deal with that? Read this article and when you get to the bottom read the 'Take Action' section.... I'm planing on getting some brochures to hand out or mail to these places and you should too!
