http://motherjones.com/blue-marble/2012/02/birds-near-fukushima-hit-harder-chernobylBird populations in Japan's Fukushima Prefecture appear to be more whacked by the effects of low-level radiation than expectedbased on responses by the same species around Chernobyl after that nuclear power plant disaster. This according to a new paper in the science journal Environmental Pollution.
Last July, four months after the earthquake and tsunami, a team of European, Japanese, and American researchers identified and counted birds at 300 locations in Fukushima prefecture between 15 and 30 miles (25 and 48 km) from the nuclear complex. Most of these areas were still open to human occupation and were experiencing external radiation levels from 0.5 to 35 microsieverts per hour.
The team compared the results to their similar investigation in the Chernobyl Exclusion Zone between 2006 and 2009, 20 to 23 years after that nuclear disaster.
Their findings:
* Overall, as expected, the bird community in Fukushima declined significantly in the more contaminated areas.
* For 14 species of birds that appeared in both Fukushima and Chernobyl, the decline in population size was more pronounced at Fukushima than Chernobyl.
* Among all birds, including the species not common to both areas, more birds declined in Chernobyl than Fukushima.

These birds are adapted to human environments. When the humans leave, of course they'll have trouble. Increased radioactivity only adds to their troubles, but I doubt very much it's the principal cause of declining numbers.

(38,326 posts)I think the vast majority of human industry is vile and very harmful to the natural environment.
But I'm not going to pay $31.50 or even drive to the university library just so I can pick apart a study that, on the face of it. seems to suffer some very obvious flaws.

(29,798 posts)Since you have no idea of the details of the study, your claim that it has "very obvious flaws" is purely a product of your imagination.

(29,798 posts)Your intent is to promote and protect nuclear power.

(38,326 posts)I think Tim Mousseau and Anders Pape Møller are harming the anti-nuclear cause. The "science" here isn't credible.
And I'm not promoting nuclear or any other form of electric power. I think they all suck.
Hunter, as Emperor of the Earth is a Radical Green Luddite who would be tearing down power plants all over the place. The Colorado River would flow unimpeded to the sea, the coal mines would be closed, fossil fuels banned, the electric grids dismantled. Nuclear power would be unnecessary. 99% of your transportation needs would be met by walking. If you wanted to travel you'd be taking a slow boat or train to wherever you wanted to go, maybe 35 miles per hour, tops. Ten days to cross the USA ain't so bad. You need a vacation and whatever "productivity" you take pride in is bad for the environment and toxic to the human spirit.
That said, I can't make a huge fuss about nuclear power so long as we are still burning fossil fuels (including natural gas) and maintaining the giant hydroelectric systems that have destroyed our riparian environments.
If I seem to be "promoting" nuclear power, it's only because I think most other ways of generating electricity are worse.
kristopher
(29,798 posts)At least you are partially forthcoming; "If I seem to be "promoting" nuclear power, it's only because I think most other ways of generating electricity are worse."
You practice a form of "greenwashing" on behalf of nuclear.

(13,508 posts)i.e., your bloody-minded dedication to the cause of smearing anyone whose opinion
dares to vary from your own.
Hunter has clearly stated his position on this (not for the first time either) and even
though he is a clear ally for the anti-nuclear "lobby" here, you still persist with your
tunnel-visioned attacks on him.
You need to understand that other people *are* allowed to hold opinions, beliefs
and attitudes that differ from your own *opinions*, *beliefs* and *attitudes* as
otherwise you risk undermining all of the good that you yourself do: the beneficial
articles & the factual counter-arguments.

(usually only for a week at a time) but at least the birds would be able to
go to a neighbour's feeders if mine did run out.

(19,258 posts)Feral cats wreak havoc on songbird populations, and many papers have reported people abandoning their pets in the rush to evacuate.
If hundreds of thousands of domesticated cats were released into the wild at the same time with nothing to eat......
kristopher
(29,798 posts)I think about 80,000 households total have evacuated
They reproduce quickly and eat both eggs and baby birds.
But I think the assertion fails before it even gets that far.
Finding a signal attributable to radioactivity in this highly disrupted environment seems unlikely.
"Our results point to the need for more research to determine the underlying reasons for differences among species in sensitivity, both initially and following many generations of exposure, said Mousseau.
In other words, please send money...

(29,798 posts)Radioactive cesium registering some 20,000 becquerels per kilogram has been found in worms 20 kilometers from the damaged Fukushima No. 1 nuclear plant.
The cesium was detected by a team including Motohiro Hasegawa, chief researcher in soil zoology at Japan's Forestry and Forest Products Research Institute. Worms are a source of food for many wild animals, and it is feared that radiation could gradually accumulate in the bodies of animals throughout the food chain.
The research team's findings will be announced at a meeting of the Ecological Society of Japan, to commence in the Shiga Prefecture city of Otsu on March 17.
Researchers dug up between 40 and 100 worms in national forests in the Fukushima Prefecture village of Kawauchi, which lies partly in the exclusion zone around the nuclear plant; the village of Otama, located 60 kilometers from the plant; and the town of Tadami, about 150 kilometers from the plant, between late August and late September last year...

Fukushima's agricultural area is under intense cultivation and the rich soil is worked several times a year deeply and completely; meaning, I believe, that the density of earthworms is very high.
The forested areas make up most of the rest of the region. There are similar reports of high levels of bioaccumulation in the insect populations there.
Yes. More research is needed.
