Fish populations change as ocean waters warm

NorthAtlanticFish

Marine ecosystems are changing as ocean temperatures rise according to Global Change Biology. Remember, when thinking about the future, it’s not what happens, but what happens because of what happens.

One example of “what happens because of what happens” is the overfishing of marlin and shark off of the California coast. That is what happened.

What is happening because of this?

The numbers of aggressive squid appears to be growing near inhabited beaches, making them even more dangerous for swimmers and divers. ABC News in Los Angeles, for example, reported an explosion in the squid population off the southern California coast.

What happens because of this? We’ll see.

But a possibility may be that swimmers may no longer fear the shark fin but fear the squid tentacle. Imagine this: rather than being attacked by a shark, a swimmer is dragged by the feet hundreds of feet under the sea until their ears explode.

Ok, enough Hollywood. Back to the warming waters of the Atlantic.

The consequences of warming waters is that fish accustomed to warmer waters are pushing into the North Atlantic. Will cold water fish like Cod disappear and be replaced by Sardines? And, the million dollar question, what might happen if this happens? The potential consequences are many and, as of yet, unpredictable.

Welcome to the Anthropocene

Look carefully at the photo. What do you see? Those of you who have experienced the beauty of the California coast line will need to brace yourselves. You’re looking at the floor of the Monterey Bay.

A recent study revealed that 33% of the debris on the floor of Monterey is plastic. Over time this plastic solidifies into a new “rock” called plastiglomerate. This is not just trash. It’s an artifact left behind by us. On hundred thousand years from now a future archaeologist may find the debris in our photo as they burrow through the geological deposits and they will seek to know us through that which we left behind. In my book, Makers of Fire, I discuss the “future” artifacts which we are creating. Think of them as the stories we’re telling future generations.

Welcome to the Anthropocene. The Anthropocene is an informal moniker of geological time. It means the “time of man”. The formal name of our epoch is the Holocene which began approximately 12,000 years ago. The anthropocene demarcates the point at which humans began to mark the earth. The beginning of the anthropocene is variously dated. Some date it very recently to the time of the industrial revolution. Others take it back a bit further to emergence of cities some 10,000 years ago. I think of it as beginning some 2 million years ago around the time we discovered fire. 

Genesis chapter 1 contains a creation story that, in the end, portrays God as the One who makes living things thrive. Thrive. That’s the word. In this creation story humans are created in the image of God. We are most like God when we make life thrive. Now look at the photo again. Every person that reads the Genesis story in seriousness and couples this with what we are learning about our Earth needs to make a sharp turn back to the earth on mission… a mission to co-create the world with God and make it thrive.

That’s the story we want to tell future generations.
