Earth Song

While listening to MJ's earth song, I feel my heart is tearing. How come our earth turns out to the current situation! Everywhere occurs quake, tsunami, cyclone ...  All these catastrophes are as a result of our earth getting sick. Who's the culprit? Humanity.  These days, people seem to wake up. Al Gore, the former American vice president and a global-warming guru, is preaching everywhere about the seriousness of our earth demaged. Now that everyone here is trying hard to save the earth. It's high time for us doing our part.
