Are we on the Titanic?

Someone was talking on the radio today and I think they had a good point. They suggested that we were all going along blindly through life, not really being aware of the problems around us, and the damage we are causing to the Earth. The analogy they used referred to the Titanic - we are all like the passengers sitting around listening to the orchestra and sipping champagne while the ship is slowly sinking under them. Surely it must be time to wake up and actually do something instead of just talking about it!
