Dear, Eyjafjall the eruption (Iceland) and the air that has caused chaos has exposed the vulnerability of it all. And so, we are vulnerable and nothing happens. It took a long time to be who we are, and no time can remove.

You tell a story, an exciting adventure. 5,000 million years ago the Sun was forming, and yet not far from him, a great cloud of dust still in the process of condensation. The result of these two processes was the formation of a large ball-like appearance that today is the fire: the planet Earth. A huge meteorite collides on the surface of that primitive Earth and due to the impact of large fragments projected out into space. The sites revolve around the Earth and slowly took up the same orbit, forming a single ring around the planet. Condense and then take the form of a sphere: thus was born the moon. Over time the moon will gradually away from the Earth to fill his current position.

A few hundred thousand years later, the pressure inside the burning earth has increased significantly, the crust of the Earth and its entire surface yields are gigantic volcanoes and vast lava fields. These volcanoes expel gases that form the first atmosphere consisting of nitrogen, water vapor and carbon dioxide.

Gradually the Earth cooled, water vapor condenses and rains are heavy. Rain for about 100 million years and as a result will form the oceans. For the first time are given the appropriate conditions on Earth for the origin of life, that arise in the oceans.

250 million years ago there was a single continent called Pangaea, where he began the reign of the dinosaurs. After this immense continent fragmented and blocks resulting develop into different areas of the Earth.

The impact of meteorites remains fierce. 65 million years ago a meteorite falls in what is now the Gulf of Mexico. The explosion is so impressive that the entire atmosphere is filled with a gigantic cloud of dust. The Earth is covered by a dark veil, the weather cools abruptly and many living organisms such as dinosaurs, extinct species that still give rise to winged dinosaur ancestors of birds as we know them today.

When the weather gets more bearable begin to develop the mammals, including man. Since its appearance as we know it today, about 200,000 years ago, modern humans have managed to colonize the planet. Can even observe the planet from space that has been born.

In the future, the Earth and life that exists on the surface will continue to evolve, Africa closer to Europe and lead to the disappearance of the Mediterranean Sea. Billions of years later, Earth will become a desert because the scorching sun, already close to death, dramatically increase their size. The heat generated is excessive, extraordinary, and trigger the end of life on Earth. This will be what was in its infancy, a giant ball of burning lava.

Finally, the heat of the sun so that the Earth will literally evaporate, be transformed into a cloud of gas and dust. The Earth will disappear after having existed for almost 10,000 million years. So today, we passed half of its existence.

What I have described is the beginning of the book of Eduard Punset fear as Somos Somos (Ed Aguilar, 2009) now I'm reading, and reading coincided with the eruption of this volcano that bitter Life. Sure, after this story, do not be surprised if we live surrounded by volcanoes, and even the entire planet could be surrounded by a cloud that is not allowed to fly airplanes.

This possibility has made me think: How many active volcanoes are known? The Global Volcanism Program ( www.volcano.si.edu ) says it is very difficult to define the term "active volcano" but provides some relative terms quite illustrative:

Dear, this is Earth, our Earth. What if I do not want the aircraft? Nothing. Economic losses? Nothing. Lives, much as they are the only important. So hard for me to understand the fuss the airlines. The volcanic activity is a risk, we know, and therefore within the absurdity of it all, if they had not foreseen the risk is your problem, the Earth is volcanic and will continue.

This truth based on science makes me think at the moment in which we live, crises are events that are typical of what we are. The economy based on the money in the amount of money, either to refer to earnings, sales, GDP, at market value, the deficit, the mortgage, etc.. The economy is quantitative, numbers are going up and down, but forgetting their social, emotional, psychological and ultimately forget their human origin, and if we see literature as the "economists" of the eighteenth, nineteenth and early twentieth - Adam Smith, Thomas Malthus, David Ricardo, John Stuat Mill, Karl Marx, Vifredo Pareto, Alfred Marshall, Emile Durkheim, ... - have little to do with the current predominance of economists today. They currently are labeled by philosophers and sociologists, intellectuals were trying to explain the workings of society and proposed alternatives to what they think it was that was not beneficial. And not until early this century that the Nobel Prize in Economics recognize the research of the influence of psychology and sociology in the economy.

Why I say that crises are events that are characteristic of: human beings with all the good - what else - and the bad. Crises, like the volcanoes are part of our context and show, also, our vulnerability. Consequently, all we can do is be aware of the risks and minimizing their impact on our daily lives and when they explode, they strive to manage the consequences of their best, because when not so crises are even more crises.
