Overfishing: doom of our oceans

This is a really nice photogallery published here by the Natioanl Geographic website. It's about the overfishing a problem that it's not affecting the public opinion as much as it should. It's enough the following statement to understand the real size of the emergency:
"Seventy-five percent of fisheries are overfished, if nothing changes, all fisheries will have collapsed by 2050." says marine biologist Enric Sala.
"The solution is involving all levels of society, from consumers to policy makers.
The solutions exist, we just need the political will to implement them at a large scale"
In my own small way I invite you to visit the National Geographic gallery and to read all the interesting captions of the pictures... there a lot of interesting facts to learn about. After that you may also find interesting a post I've written about the Bluefin Tuna a king of the oceans whose own survival is in extreme danger due to overfishing.
