Quaked

I have started believing that we use too much concrete in our buildings after seeing the earthquake related devastation in Pakistan and India. We need to use more wood and other light weight environment friendly material.
I wonder if the ice melting away at the poles and the earthquake and the hurricance is spun off the same thread!? No, i dont believe the world is coming to an end but I am disturbed by the lack of a unified thought process and follow through. I am also surprised that all this does not jolt me into a proactive state. I dont think figuring out that most of our 'problems' are petty is enough.

I am listening to the 'Skating on thin ice' by pink floyd..

If you should go skating
On the thin ice of modern life
Dragging behind you the silent reproach
Of a million tear-stained eyes
Don't be surprised when a crack in the ice
Appears under your feet.
You slip out of your depth and out of your mind
With your fear flowing out behind you
As you claw the thin ice

Who and what are these guys singing about?
