Nuclear Powerplant

Japan's Fukushima Daiichi nuclear power plant suffered three meltdowns last year. Paired with hydrogen explosions , these meltdowns allowed radioactive material to escape. So what's the effect on the environment and human health? The first clues come from what's called the pale grass blue butterfly. This delicate insect's wings change color and pattern in response to environmental changes . The offspring of female butterflies caught in the Fukushima region six months after the meltdowns sported such color-pattern changes, as well as deformed legs, antennae, wings, and even eyes. The deformities persisted and got worse in the second generation of offspring as well.
