This album issues affecting our world at various levels (political, environment, business ...) was at times a tendency to pour into the easy comment and not supported by facts, like "although it is known leads us to an overpopulated world unable to sustain itself. " These passages are, however, largely offset by compiling ideas and actions addressing the crowd problems is drawn up. While all do not resonate with the same intensity, throughout my reading I was led to think about my own commitment to sustainable development of our planet. This is a good way to review my current commitments and actions, and think about what I can do in the future. There certainly for everyone the tracks to become a citizen closer to its environment, and make them want to get involved in his community and in the world.
