So in other words, you are willing to ruin the oceanic ecosystem to prevent a storm which actually makes life better in the long term? Not only that but using cryogenic liquids!?! You not only kill the entire ecosystem but you kill the livelihoods of thousands of people. If you don't want to worry about hurricanes don't live near the coast. Its as simple as that.
