Confused Turtles


Like a baby duck that will follow the first moving object it sees, baby turtles will head towards the first lights they see. This is most often the light reflecting from the ocean. This instinct is supposed to lead them to the ocean, and it is believed to set their magnetic compass to aid them in their return home. If the turtle’s first sight of light is of city lights, however, they will make their way towards those instead. Even when turned to face the ocean, supposedly the turtles will remain disoriented. This is yet another unfortunate reality of human activity disturbing nature.

Bluefin Tuna


Bluefin Tuna have the ability to live in extremely different climates; they are able to dot his thanks to their fatty bellies. Unfortunately for this species of tuna, however, their fatty bellies are the reason why they are now a threatened species. Sushi makers and eaters around the world love the buttery, bluefin tuna belly. In the Mediterranean alone it was estimated that 50 thousand tons of tuna – which is 50% of the global market - was caught in just one year! No wonder there people were shocked to hear that the Federal Government decided not to put Bluefin on the endangered species list. (More can be read about their reasoning here.) The tuna are being so over fished now that the prices have fallen, which will only lead to profit hungry fisherman violating quotas.
