Bluefin tuna are some of the most endangered fish in the sea. Prized by the sushi industry for their delicious flavor, populations of bluefin have declined precipitously in recent decades.
They also may be the first species of fish to be driven to extinction by commercial fishing. Normally, when populations of fish get low, it isn’t profitable to fish for them anymore- thus they are not driven to extinction. However, a single bluefin tuna can sell for hundreds of thousands of dollars, so it is still profitable to fish for the last one.
WhySharksMatter beneath a whale shark
Following the deaths of two whale sharks in 2007, many animal rights activists harshly criticized the Georgia Aquarium for keeping these animals captive in the first place. I recently visited the Georgia Aquarium for blogger day, and the aquarium’s Chief Science Officer Dr. Bruce Carlson agreed to answer my questions about their whale sharks. I know that many of you have strong opinions about shark issues, but I wanted to provide the Georgia Aquarium’s side of the story.

I am, in general, a supporter of animal rights. Animal abuse sickens me, and I really believe Ghandi’s famous quote that “you can judge a society by how it treats its weakest members”. That said, while it’s disturbing to see a rabbit which has gone blind from exposure to a potential new shampoo, I’d rather have a rabbit go blind than a human child. More importantly, while it is troubling to infect a chimpanzee with a disease in order to study how to cure that disease, such research unquestionably saves human lives. That’s why I was surprised to learn about the Great Ape Protection Act.

This month’s Frontiers in Ecology and the Environment has a brief article about a new proposed conservation strategy that seems perfect for a Southern Fried Science ethical debate. Northern spotted owls (Strix occidentalis caurina) are one of the most famous endangered species in the United States. While solutions to the destruction of their habitat by logging have been debated for years, a new threat has been recently identified- encroachment on their limited habitat by another species of owl (the barred owl, Strix varia). Some conservationists now believe that we need to kill barred owls to protect spotted owls.

The interwebs are abuzz with glowing reviews for Rebecca Skloot’s new book “The Immortal Life of Henrietta Lacks”. I’m currently #37 on the library reserve list (sorry, Rebecca, but I’m a poor grad student and I can’t afford to buy it). The book tells the story of the HeLa cell line, which are cells that were taken from a patient without her consent. These cells have led to important medical breakthroughs. But how isolated of an incident is this?
