fingernails. yes, you are stable hanging by your fingernails, but what a way to go. and quickly, the threat to california, hawaii, the president says don t worry about it. don t worry about it. you know, you have a piece of chernobyl in your body right now. so do i. every american has a piece of chernobyl in our bodies. but it s so microscopic it s not worth talking about. after the accident in new york city you can actually see the blip in it per liter but it was way below the danger level. so a piece of chernobyl, maybe a piece of japan s reactor, no big deal in. as far as the united states is concerned. but for japan it is a crisis of historic proportions. michio kaku, author of physics of the future, just out this week. thank you very much for joining us tonight. coming up, president obama finally addresses the crisis in japan this afternoon in a speech from the rose garden after being criticized for not doing enough about the uprising in libya and the budget negotiat
normally it s 800 work e. now we have 50 beleaguered workers doing four simultaneous actions at the same time, let s get real. if one goes over the top, shall we say, goes to the meltdown, it may make it difficult to service the others. reactor 2 has a crack in its containment. reactor 3 also has a crack. here we have 70% core damage, here 33% core damage. i mean 800 workers can t even handle one meltdown. we have 50 workers with four simultaneous accidents. and seen as heroes in the country of japan as they work so hard. thank you for some of those solutions that he discussion in his book physics of the future. millions have poured in for disaster relief in the first six days after the quake, the americans have donated nearly $50 million, but when you compare that to other disasters, it s actually quite small. in the two weeks after 9/11 more than $800 million were donated.
the cyberwar against the assault of our kids. susan, thank you so much. that wraps up this hour. chris jansing is making her way back from japan thomas roberts take over from here. desire straits to continue talking about, nearly half a million are being evacuated. thousands more cut off from help, cut off from any aid. we ll talk about that. then back here at home, bus safety. can you feel safe trusting the person behind the wheel? also, can you replace your wallet with your phone? we break down the pros and cons of that one. straight ahead. [ male announcer ] it s simple physics.
picture, but we continue to watch as this gas line leak and explosion continues. we have not heard at the moment of any casualties, but we ll continue to watch this explosion, gas line explosion there in minneapolis for you. also, back to japan, an important store what we re watching here. decidedly low tech, and it s all about really water. and cooling this. nearly 700 tons of spent fuel stored in the six reactors at fukushima. if the cooling pools are empty that are on the top of those reactors, and those rods that are stored there allowed to overheat, radiation will spew into the air s we have the professor of physics at the, and also author of physics of the future.
in february despite a slow start to the month after those stubborn snowstorms. consumer confidence also jumped to a three-year high in february, analysts warning rising gas prices could force those shoppers to pull back on spending. we ll watch it at the pump. arthel: a new warning from scientists suggesting the earth may be on the vench of must mass extinction, similar to the one that killed the dinosaurs. it s happened five times in the past 540 million years but this time around experts say we may be able to stop it. michio kaku is a professor at the university of new york and author of the new book physics of the future . looking forward to the new book, of course. dr. kaku, getting right to it, which species will be most at risk? so far if you analyze the last few hundred years of life on earth human activity apparently has wiped out 1.4% of all plants and animal species and it is 100,000 to 1000 times lasser
