Tropical forests at risk. Google Earth helps us to see from the truth.

Some numbers: forests Tropical rainforests occupy about 6% of the total area of \u200b\u200bland where some 50% of all species. Today deforestation at a rate fast: within fifty years, these areas may no longer exist, if nothing is done about it.

But how deforestation happens in reality? Let's see what happens in Brazil.

The forest is allocated to small farmers, who shall be able to burn it to grow, the crops may continue for 2, maximum 3 years. Because of a combination of important factors (limited thickness of the tropical soil, abundant rainfall and high evaporation), the completely loses the soil humus, and therefore its fertility and become totally unproductive. These areas are so impoverished in the hands of ranchers, exploiting what little is left. The end point of the big industries are mining, which they build their plants when the areas have become veritable deserts.

It has a certain effect in Brazil think that 1% of farmers (ricchi!) owns 43% of cultivated land. The poorest are left of the actual plots of land: in short these are a Asorti of "slaves loggers" in the service of the richest and most powerful.

I invite you to take a look to the Amazon Rainforest Google Earth. Look Rondonia, Brazil, and you realize that what you feel is not false alarms. Think that once was all green. Now there are those lines that cut through the forest roads are. And those parallel branches that depart from these streets, on both sides (which seem to
fishbone) are nothing but the future directions of deforestation. Streets of destruction.

PM10 and PM2.5: why do bad?

Very briefly, the atmospheric particles, well known as "PM" (Particulate Matter), is a very heterogeneous set of particles.
The classification provides a breakdown in three classes according to the diameter of individual particles:
- coarse : between 2.5 and 10 mM, the portion is coarser (one known as "PM10").
- end : between 0.1 and 2.5 mM, of intermediate size (the less famous "PM2.5").
- ultrafine : particle diameter less than 0.1 mM, very small.

What I do not know is that it is more dangerous than PM10, PM2.5, but!

The larger particles, in fact, are trapped in the first part of the respiratory system (nose, trachea, bronchi), while those actually respirable, ie, those who arrive in the alveoli, are the finest. And 'here pursuing their toxic action is taking place here the exchange of oxygen and carbon dioxide.

But what is a toxic effect? Must be a short introduction: on the surface of these particles are a true infinity of substances, both natural (crustal elements, pollen, bacteria ,...), both anthropogenic (pollutants from traffic, PAHs - polycyclic aromatic hydrocarbons, nitrates, sulfates ,...). Understand that if highly toxic elements reaching the alveoli ... the damage is inevitable.

What happens at the cellular level, shown in numerous studies, is the breaking cell membranes: both outer membranes (ie, bounding the "borders" of the cells, biologists will forgive me but my purpose here is not scientifically describe the cellular morphology) and the membranes of organelles within cells. The main targets are in fact the mitochondria, which in very simple words are the power plants of cells: whether their ability to provide power fails, all the basic processes are compromised and the cell dies.

The question that arises is ... why, today, there are still no laws regulating the emissions of PM2.5? And yet, because the newspapers and on television always insist on talking only and only when the fraction of PM10 PM2.5 is more harmful?

Probably not depress us, that's why.

How to clean the monuments from the "black crust" caused by smog

Even the monuments need to clean up every now and then: in fact, a bio-restoration.
Pollution in fact the formation of the so-called "black crust" on the surface.

I fished out an article in the Corriere della Sera 07/09/2006, reporting a study by the University of Milan where it says that for this purpose may be used for micro-organisms.
The procedure involves the application of live cells of bacteria desulfuricanti ( Desulfovibrio vulgaris) and covering with plastic film for a time ranging between 12 and 72 hours.
The patent has been filed under the name " procedure biopulitura surfaces of different chemical nature of artifacts and buildings ", and is different depending on the type of work to be restored: such bodies there are in fact more suited to marble, the other frescoes.

Kite Gen, energy from wind at high altitude

The source of energy used by this system is the wind, but not the one already used by traditional wind turbines on land (onshore ) and at sea (offshore ). In fact, these structures are unlikely to exceed the 100 meters in height, for both problems impact on the landscape, for both technical and economic difficulties in creating structures resistant to mechanical stress.
In this case the idea is to use the wind at high altitude (between 800 and 1000 meters) without the construction of massive assemblies. The company that designed this type of system is the Kite Gen Research, which will carry a video well done and very effective in conveying the working mechanism of the system.

Switzerland, ecological homes

A video I think cute, short and not meant as an "installed on each existing house such a thing", but rather as a "Let us realize the potential that surround us, and if we can do something in our little".
What is it about? Photovoltaic solar panels, hydrogen as a substitute for fossil fuels, electricity sales in the network, ...

Review Meeting with Asia Argento




After several years of waiting I finally met my idol Asia Argento at the Rome Film Festival , where among other things, held a discussion on Onedreamrush , a work that brings together 42 short films of many directors, each lasting 42 seconds, sull'interpetazione of dreams, produced by her husband Michele Civetta. I managed to speak to us, to embrace it ... and she remembered me, when I wrote on the radio. What about ... a fantastic experience. One of the many dreams that I'm slowly realizing .
