It is the "something" that is the problem. If we are attempting to purify it, that is what is already being done. If it is sealing it off so it does no more damage... That was the situation as it was before we arrived, a method that was already failing before we arrived. The issue is finding a method that both allows it to live, yet prevents it from killing more people. Unless we can provide an alternative...

[Please, say you have an idea we can try.]
