Marine life rides Japanese debris to North America
#1
In 2011 Japan was hit with a major tsunami and much debris was washed out into the Ocean. By 2012 this debris began appearing on west coast beaches. It is arriving and it has hitch hikers. Unusual Japanese marine life is traveling with the debris. 
These are sea creatures that have never lived on the North American west coast before. It is unknown what their impact will be on the environment.

Previously marine animals couldn't have made the trip. They would have been clinging to biodegradable materials. Now with our modern indestructible waste, many animals have made the trip. 
It might seem exciting to think of seeing new and unusual  creatures  in old places, but we don't know what the consequences will be. It is like fish farming Atlantic Salmon in the Pacific Ocean. We don't know what the consequences will be.

I know most people were scared about radiation from Fukushima. This has the potential to be a much more serious and long term problem. Invasive species can destroy and ecosystem. Any number of these travelers could turn out to be invasive. We won't know until there is a problem. And that not knowing is a problem.

Yes you are right. The new arrivals will change the shape of everything locally. It's hard to guess what will happen, and the results will probably take some time to appear. All those little creatures were saved by riding on debris. That's one nice thing. But the environmental impact is another thing.

It is nice to think of survivors making it to safety, but the conditions will not be right and anything can happen. 
We have a giant science experiment going on and no one knows what the outcome will be. It never seems to go well when species are released in strange environments. In this case it will also be the best and strongest of a species that makes it to North America. We could see a real decline in native species. There could be species that interbreed and that can have a whole new set of problems. 

It will be years before we know what is happening.
