Japan, nuclear waste and sunflower

so they are planning to plant as much sunflower as they can. it's a symbolic, they said. after renouncing 'live by principle' axiom, I believe what we should do is more effort and thinking to minimise what ever risk we face. why symbolic? this kind of thing reminds me to my previous boss who always said he's talking in symbolic and expecting people to understand. what the meaning of that? could he just got straight to the point instead of 'symbolism' which people may not understand due to 'poor or stupid symbolism'.
