Japan was hit by Tsunami and it was the worst earthquake ever happened in Japan. We've observed scores of natural disasters over the years. Don't blame the earth for being too old. Blame US, the PEOPLE.
We've made myriad of destructions to the world. The saying "How man can survive in this world" is no longer appropriate, but "How the world can survive with the people" is more suitable. Unless the people stop doing all the wreckage and killing, then the world will be in peace. So, stop war (the most important), open burning, polluting, toxic dumping, oil spilling, and et cetera. Start preserving our nature so that the world will be a better place for us and for our children and the generations after them.
