Gaia or Medea, what future for the Earth?


In view of the climate conference to be held next December in Copenhagen, from which we can expect some important decisions concerning protection of the planet, I decided to create a sort of path towards all 'event staged approach to addressing the key issues related to it. With this in mind I decided to start the conversation by focusing on two main theories that predict what future awaits the Earth and its inhabitants, and which also appear to differ significantly from each other. The
Gaia theory, which takes its name from the ancient Greek goddess of Earth, mother and protector of all life forms, claims that our planet, for all damages caused by man, is nevertheless capable of regulating itself and evolve to ensure the welfare of its inhabitants. The theory of
Medea, which instead takes its name from the mythological character of Medea, in fact, the wife of Jason and famous for murdering their children, argues instead that the evolutionary system of the planet is inevitably destined to end in the extinction of life of its inhabitants. In essence
Gaia sees the earth as "benign mater" Medea and instead framed as a merciless stepmother and inhospitable.
The two theories are actually much more complex and groped to explain in detail would involve a much longer speech.
The Gaia theory is not new. It dates back to 1979 and was made by British scientist James Lovelock, according to which life itself is to regulate the atmosphere and Earth's climate in order to make a living through self-regulation mechanisms of its main variables: temperature, oxygen, acidity, etc..
In this theory, all things considered, fairly comfortable, he chose to oppose the American scientist Peter Ward, who sought to show that, for the earth's temperature in hand, in reality that proposed by Lovelock is a beautiful fairy tale and instead the latch temperatures recorded on the planet over the millennia can be attributed to the evolution of new species of life.
Over the past 565 million years, or the beginning of the evolution of animals on Earth, there were as many as 15 mass extinctions and 10 extinctions minor all caused not by external events (such as the collapse of a large meteorite on the planet), but on the emergence and subsequent evolution of new species that, digging their own space in the ecosystem of the planet, however small, have come inevitably to delete the existing species and in fact incompatible with the new arrivals.
You know the new American settlers who actually phased tribes Indian in America? Here, something like that. In summary
Ward, with his theory of Medea, says that life seems to actively pursue its own end, leading to the Earth faster and faster when the inevitable day return to its original state: sterile. According to Ward
the process of self-destruction has already begun: the concentration of CO2 in the atmosphere gradually decreases until it disappears, thus preventing photosynthesis and in fact the whole life cycle connected with it.
There is however some good news: the process, although started should be completed within 500 million years ... So there is still a bit 'of time for a movie and a good book!

L 'eco-diamond Pratolino


inaugurated, Saturday, Oct. 17, in Villa Park in Pratolino Demidoff, the "Diamond". It is a structure that weighs 30 tons, is 12 meters high and has a diameter of 8, all in glass and steel, capable of producing energy for the first time combining solar and hydrogen technology. The project is experimental in nature, was carried out by Enel in collaboration with the University of Pisa. The goal is to produce clean electricity through photovoltaic panels 38 and then store form of hydrogen within three balls that act as storage tanks and placed inside the panels.

The plant will have a power of 11 kilowatts and will provide energy to the Park Pratolino. Among other things, the energy accumulated from the Diamond should provide power to electric bikes that will be made available to park visitors.
For the first time you can then use the electricity produced by the panels during the day even at night, when they must return to the use of the network as photovoltaic panels, the absence of solar radiation are not able to produce energy . The
experimental technology applied in this project is today without doubt extremely expensive.
However laudable attempt that with time and thanks to the ongoing experiments could lead to less expensive facilities. ( to learn more about functional details, click with the mouse on the box "day" and "night").

The plant will be owned by Enel for free but will sell the energy created by it for use of Park Pratolino.

" Confessions of an eco- sinner "by Fred Pearce

Did you know that to make a wedding a few grams of gold on average it takes 2 tons of rock excavated to a depth of several kilometers and 5 tons of water? And
third of the products sold in our supermarkets contains palm oil in the manufacture of the forests are destroyed?
Did you know that is the production of cotton to have caused the disappearance of the Aral Sea, once the 4th largest lake in the world?
Here are just some of the information that you can discover by reading "Confessions of an eco-sinner" by Fred Pearce, (Edizioni Ambiente Euro 22.00).
Despite the title the book is not only interesting but presents a wide-ranging and well-documented strictly, the origin and destiny of all the products of common and daily use of which we can not (it seems) do less to live.
Pearce is a British journalist who works as an environmental consultant for the New Scientist. It took several years to visit many different places on our planet in order to know where they come from, who made them and at what cost to the environment, the products we use every day.
The survey of the gold mines of South Africa, to continue in the rainforests of Indonesia, Australia, Uzbekistan addressing all the issues that concern our daily consumption: food, clothing, computing, energy consumption, waste.
In these pages we find for example that the banana, one of the most eaten fruit in the world, being a mutant sterile and free from seeds and cultivated worldwide in a single variety in America, Asia and Africa, (the "Cavendish"), is seriously threatened by insects and diseases that may cause extinction.
Do not believe us? E 'already happened in the '50s when the banana varieties that were not power but the current one called "Gros Michel", according to experts richer and sweeter than today. It is unfortunately vulnerable to a fungus that caused definitive disappearance.
And again, the process of production of aluminum is one of the most expensive in energy terms and in terms of emissions of carbon dioxide in the atmosphere.
in the world are produced around 250 billion cans per year! Pearce, (which quotes several times in the book studies the Friends of the Earth) along the entire journey to discover the stages of production of a can from the region of Queensland (Australia) where one of the largest mining companies in the world, the Rio Tinto, extracts bauxite, which is then transported to Gladstone where it is refined to alumina. The production of aluminum has boundless ecological footprint. I quote a single fact: the production of a single tin results in the emission of 260 grams of CO2 or a quantity of gas sufficient to fill 300 cans!
The last part of the book is devoted to possible alternatives, namely the possibility that the second man Pearce has yet to save the planet and himself, as long as you decide to change course immediately. So we learn the importance of recycling: the recovery of aluminum from the return to the market which may result in energy savings of up to 3 / 4 of the cost of virgin aluminum production, the example of Tanzania where there is a trade fertile based on the recovery of used Western clothing, to arrive in Nairobi where the "Computers for Schools Kenya" recycles old computers from Europe and North America giving us then to schools across the country. Pearce finally gives us a framework of good examples to imitate, and already adopted by several cities in the world: the development of so-called "urban agriculture" in Valencia, the cooling system of buildings built in Toronto using the waters of Lake Ontario, the truck San Diego's trash fed with methane produced in landfills, and much more.
If the part dedicated to the research documented ineccepibibile is, of course not all the British journalist's personal views can be shared: as rightly pointed out in the preface to the book meteorologist Luca Mercalli, makes little sense to support the purchase of beans produced in Kenya and exported to the major European countries in the name of fair trade, much better choose to buy local seasonal produce. But apart from any conclusions, perhaps a bit 'rushed the book is really interesting and useful for those who want a complete picture of production processes and their impacts on the planet. I think it could be easily adopted by teachers in schools and in particular I find it useful to that process of acquisition of awareness and sense of responsibility that we set as its primary goal. In
fun latest film W. Allen the main character, (among other things supports the extension of capital punishment in all dog owners who do not collect the excrement of their pets!), argues that the human species is now composed only of individuals losers, selfish and cowardly, and therefore it is hopelessly doomed to extinction. Maybe by reading this uplifting as we try to give a glimmer of hope in the younger generation more ...
