Nuked Coral Reef Bounces Back
sm62704 writes "I found this New Scientist article interesting, as I was actually alive (albeit very small) when Bikini Atoll was H-bombed. The article says that the reason the reefs are now flourishing is because they are mostly undisturbed by humans, who are afraid of the radiation. Background levels there are now 'similar to that at any Australian city,' while nearby islands haven't been so lucky.'When I put the Geiger counter near a coconut, which accumulates radioactive material from the soil, it went berserk,' says Maria Beger of the University of Queensland in Australia."
Would sure as hell make survivor more interesting.
"oh, and by the way, anything you eat is likely radioactive"
Maybe make the first episode with reality TV execs on the island....
Queue Gilligan's Island jokes too.
...
Were there lots/little/none ? Oh, come on - that would be one of the most interesting things to tell us. We are all so worried about ''nuclear power fading your genes'' - we now have a 60 year experiment that could tell us about long term effects but they are silent.
now we just have to bomb the shit out of Australia so our scientists can proudly proclaim "these coral reefs are far LESS radioactive than any Australian city!"
Yes, I'm left. You have a problem with that?
REAlly, I think it proves that after we screw things up royally on this planet to the point where we are no longer able to live on it, it won't take the earth too long to bounce back and thrive once more. Hopefully the next set of inhabitants on this planet will look after it better than we do.

For those of you who are anthropologists as well as zoologists, it should be mentioned that there were native inhabitants of these islands that were forced to move before the tests.
We did it to Native Americans on the continental United States as well but it really bears mentioning that there was a pretty gross injustice paid to these peaceful peoples in the name of atomic testing. I remember watching this footage on an ABC special as a kid and I luckily recorded it so I could watch it over and over again. When watching project Baker, I kept thinking "Wow, that's impressive, that was somebody's home."
I suppose I'll be called a self-hating liberal but I believe we should never forget the price we pay for the weapons we hold. These weapons that were supposed to be the end of war aren't and any future horror developed to stop war won't be the end to war either.
Just imagine what the look on your face would be if someone showed up and told you to evacuate your state because it was now going to be used for nuclear testing. You probably wouldn't be very happy to leave your home in the name of warfare.
My work here is dung.
I was rather stunned when, planning my trip to AU a few years ago, I realized that ONE nuclear sub could take out the whole country!
Or at least send it to Mad Max-land.
Physically AU is huge. Roughly the size of the US. Superimposing a map of one on the other gives fairly accurate driving times and distance calculations.
Demographically it is very very small.
I also figured out the real problem is water. While the US, EU, and CN have large navigable rivers running deep into their continents, AU has nothing to bring water to the center of the country (or more accurately there isn't enough rain in the center to drain and form navigable rivers).
AU could be a super-power if it had enough water to support a population of 300 million. Instead it is so dry they are lucky to have 1/10 of that at about 22 million.
Or they could be rated AA-grade! Maybe the radiation pre-tenderizes them. Sorta like they have been cooking really really slowly their entire lives.
What customer of illegal fishermen checks the stuff with a geiger counter?
And due to alleged radioactivity of the area, patrols are likely scarce, law enforcement not too fond of exposing themselves to radiation.

Its not too bad but it does cause some interesting side effects.
:P
What? You thought kangaroos were natural?
Animal life around Chernobyl is also doing well. That's not an indication that radiation is harmless (most animals are shorter lived than humans, so they can tolerate more radiation), it's an indication that human presence is even more harmful than radiation.
The full story is that although some of the corals have bounced back remarkably, the nuking has also resulted in the localised extinction of some more sensitive sensitive species However the research has also revealed a disturbingly high level of loss of coral species from the atoll. Compared with a famous study made before the atomic tests were carried out, the team established that 42 species were missing compared to the early 1950s. At least 28 of these species losses appear to be genuine local extinctions probably due to the 23 bombs that were exploded there from 1946-58, or the resulting radioactivity, increased nutrient levels and smothering from fine sediments. Article also has some good stats on the nuking itself: One of the most interesting aspects is that the team dived into the vast Bravo Crater left in 1954 by the most powerful American atom bomb ever exploded (15 megatonnes - a thousand times more powerful than the Hiroshima bomb). The Bravo bomb vapourised three islands, raised water temperatures to 55,000 degrees, shook islands 200 kilometers away and left a crater 2km wide and 73m deep.
I once heard something fascinating. After the Chernobyk accident, the radioactive cloud that contaminated (mainly) the north of Norway caused allot of fear in people, and for people's health. The gouvernment continued to slaughter and burn massive amounts of raindeer and livestock.
A friend later told me that the meat was actually fully usable, and that it's destruction may have been unnecessary. She suggested we should have fed it to the elderly population, which did not have time to develop cancer from the meat anyhow.
There will be allot of talk in this discussion about the fear of radiation, and that is why this discussion is so good. Life does well with increased radiation! Humans don't however, by virtue of the way we look at human society and human worth. What it does say however, is that fear of nuclear energy, a power source that may have dramatically less consequence for life on this planet than most other energy sources, prevents us from progressing in the energy debate! (and maybe also in space exploration, given worries of launching nuclear-powered space craft)
Check this news item for a similar case to the coral reef in the article.

You put the lime in the coconut, and drink it all up... Then die of radiation poisoning.
Science advances one funeral at a time- Max Planck
Even without husk-gripping, coconuts move... they're supposed to, thats how they get from island to island...
I think this is a note to self: do NOT eat coconuts that you find on the seashore. I wonder if anyone's realized that little issue...
Would be interesting to look at how long expected development time for the cancers you could get from these coconuts would be. Maybe for people over 65-70, the food is perfectly safe to eat! (:
With the giant mutant anemones and sponges with teeth and the crushing and the laser eyes!
.... and mutant.
To people of Japan, your cities are no longer safe. Run for your lives. The coral is back, and this time it's pissed

That has actually been a "jokingly serious" suggestion. Increasing the background radiation in an area so humans don't dare to use it or any products from that area. Works great with Chernobyl for example, the forest around the area has a lot more animal life now than before the incident.
c++;
that we totally defeat the Bikini Atoll in a nuclear war!! Woo go USA
It was silly though, back when US sentiment was so against Bikini Atoll, that everyone decided to change the name "Bikini" to "Freedom suit."
All of life has the same problem. That is the radiation induces faster changes in all. Some on birth defects. The vast majority are simply miscarried (most ppl never realize that many women suffer at least 1 miscarriage and it is due to a fatal defect). But of course, some make it to the world. The recent Indian girl who was born with a duplicated face (probably the best place that she could be born was in northern India; there she is a goddess; elsewhere she would be considered a freak) was possibly induced via radiation or pollution. For the living, it means loads of cancer. No doubt that animal life in any of these radioactive areas are suffering shortened lives due to such. In fact, I am amazed that we (USA and Russia) are not tagging these animals to see how long and what they look like at end of life. These are all living labs. Heck, I am more amazed that Hollywood has not made some interesting movies based on just these areas.
I prefer the "u" in honour as it seems to be missing these days.
Or maybe the people where the coconut washes ashore have a life-expectancy lower than that of the west, and the increased cancer risk that comes with eating it is minor, and irrelevant. Cancer largely develops late in life, and is of more concern to populations living as long as we in the first world than most other places around the globe.
Even if you killed of all the coconuts, the cost of the operation could be high. Maybe, in terms of people's life quality, the money would be wiser invested covering other issues of health in the region, giving more people higher quality of life, rather than lengthening the life expectancy of a few unlucky individuals by a matter of days on average.
A Giger counter presumably counts paintings.
I imagine that a pair of swallows, either African or European, could take one of these coconuts quite far.

I would. Coconuts have evolved in such a way that their thick, outer hull keeps it afloat should it happen to fall into water. Coconuts can float for hundreds (thousands?) of miles to distant beaches without incident. The tough, inner object that we find in stores is kept completely dry during this time. The white insides and milk are perfectly safe to eat.
Except for the radiation.
We will bankrupt ourselves in the vain search for absolute security. -- Dwight D. Eisenhower
and the increased cancer risk that comes with eating it is minor, and irrelevant.
This. One of the fun things back in HS was to take the radiation detector to various common items. Heck, Brazil Nuts, Lima Beans, and Bananas are radioactive. So aren't carrots and potatoes. Potassium, an essential nutrient is radioactive.
An extra dose of radiation doesn't mean that somebody is going to die from cancer. It all depends on the dose.
rather than lengthening the life expectancy of a few unlucky individuals by a matter of days on average.
Unless the individual is making said radioactive coconuts a staple of their diet; I'd say minutes is more likely.

Ha. Ha. Here's the deal on Bikini: 1) You can't live there. You can visit on a dive excursion. Everything is brought with you. There are bunks in the buildings, but that's all 2) The radiation is in the form of cesium, which is extremely water soluble. As a result, it is present above the waterline in the sand and soil (but not at the surface, as rainwater constantly washes it away). In addition, since cesium is SO soluble, all traces away from the shore are long gone. So it's safe to dive the wrecks, which are spectacular. 3) Previous attempts to get the cesium to bond to other elements, e.g. iodine, did not succeed as planned, and the vegetation continues to suck it up. 4) In 1946 there were around 150 residents that were relocated to Kili Island and to Ejit, so they'd like to get home some time, too. 5) If you ever get the chance, cough up the cash, learn how to dive, and GO. Most of the wrecks are deep, but the water in the lagoon is as clear as you are going to see, and the wrecks are pristine. I've done diving at a military-controlled atoll, where there is very little traffic, fewer tourists, and an active SCUBA community. It may be the best diving I have ever done.
Friends help you move. Real friends help you move bodies.
Never forget: 2 + 2 = 5 for extremely large values of 2.
>>>"Background levels at Bikini Atoll are now 'similar to that at any Australian city,'"
Note to self:
Don't visit an Australian city.
The government is not your daddy. Its purpose is not to raid middle-class neighbors' wallets and give it to you.
Almost as if they had just... evolved to cope with the massive doses of radiation they cop every day.
The tricky thing about evolution is, only the survivors survive it.
Naturally, some sub-population will survive and, lacking competition, thrive. Most humans, though, would consider it unacceptable to eliminate, say, the 50% of a population that is most susceptible to radiation (or heart disease, or any other condition) even if the surviving population was stronger and better adapted as a result.
The US free market: two halves of a government-granted duopoly are free to set the market price.
Since 2000 the annual numbers of AIDS diagnoses have been relatively constant, with an estimated 37,852 in 2006. That's people DIAGNOSED, not deaths.
Some 43,443 people were killed on the highways in 2005.
Meanwhile, 559,312 people who died from cancer. Cancer is only the second biggest killer, heart disease kills more people of ALL races. More black people die of cancer than all races combined die of AIDS.
HIV is comparitively a very minor threat, even to minorities, compared to other dangers. If you're talking about dangers to minorities you should be talking about incarceration, as a disproportionate number of our prisoners (more per capita than any other country) are minorities.
