Wow, it’s already International Cephalopod Awareness Days again! (see my post from last year’s Octopus Day about the Great Pacific Garbage Patch
Here are the Cephalopod Awareness Days we are celebrating: October 8 is Octopus Day (my favorite!), October 9 is (Chambered) Nautilus Day, October 10 is Squid and Cuttlefish Day, October 11 is Myths and Legends, and October 12 is Fossils and Extinct Species (Vampire Squid fit here as “living fossils”, they have been in the news lately, perhaps you have heard that they eat feces and corpses in the deep sea?)
In honor of Octopus Day, I thought I would go over the “State of the Oceans.” Since I’m no orator (I have no vocal cords), you’ll have to settle for my thoughts.
Right now there are 3 major issues facing the ocean today:
1. Global Warming
Whether or not you believe global warming is currently happening, or that it is humans that are causing it, the effects of global warming have been shown over geologic time (i.e. longer than humans have inhabited the earth). Global warming causes seawater temperatures to rise, which can have devastating effects on all wildlife, especially on corals. For more on coral bleaching see my last post.
Due to global warming, sea level rises faster than usual due to the melting of the polar ice caps. Ocean acidification occurs because of all the extra carbon dioxide that the ocean absorbs, and it causes seawater to become more acidic (like soda or orange juice). It mainly affects those animals that have calcium carbonate skeletons, especially the plankton at the bottom of the food chain. For more on that read Terry the Pteropod’s post on ocean acidification.
Pollution comes in many forms, including chemical (like fertilizer runoff and industrial waste), and physical (like garbage or silt). Garbage is the most insidious form of pollution in the oceans. It consists mainly of plastic in all shapes and forms. Plastic never biodegrades, and all the plastic that has ever been produced is still around today (unless it was incinerated). For more, read my previous post on the Great Pacific Garbage Patch.
Overfishing is happening all around the world in all the world’s oceans. Every single country that fishes is catching more fish than can be replaced by the birth rate of new fish. This means that most marine animals eaten as seafood are being fished unsustainably! For more information on overfishing, please watch the documentary The End of the Line.
Once again, I’m out of time. I’ll be back soon to discuss more pressing ocean issues. Please hug a cephalopod today! Or at least abstain from eating us or buying our shells (see Shelley the chambered nautilus’ post), thank you!!
