Marine biologists are puzzled by the hundreds of leopard sharks washing up dead on the shores of San Francisco for the past seven weeks.
They wonder if it could be the sign of a major problem throughout the Pacific Ocean. As both scavengers and super-predators, sharks in general play a critical role in keeping the ocean’s ecosystem in balance.
Sharks eat fish that are the weakest and help maintain “prey species diversity” by keeping other predators in check. Scientists worry that any decline in shark populations may threaten fishery operations and also indicate deeper problems in the ecosystem.

Maybe Fukushima coming to shore?
I wouldn’t want to live there either
why isn’t the government helping japan ?
I haven’t heard anything on it and haven’t seen it on the internet either. I’m a news freak so more then likely it’s hush-hush as usual. It’s coming from Japans problems with their radiation or they just beach themselves. Makes you wonder about eating the fish in the ocean anymore.
Fukishuma
Someone did allready
Pollution.

I quit eating anything out of the Pacific Ocean a couple of years ago.
