In recent weeks, many earthquakes have affected many areas of the planet, ta which unfortunately also Italy.
The explanation for this, according to a theory published in Nature, would be linked to human responsibilities that they would cause a real "collapse" of the planet. I think Anthony Barnosky, a biologist of the 'University of California.
According Barnosky Earth is near the point of no return and is preparing to face the most dramatic and radical changes for 12,000 years now, ever since the ice started their retreat at the end of the last glaciation.
According Barnosky and his colleagues who supported the study, the problem is caused dall'eccesiva pressure at which we are putting the planet at some point, impossible to predict accurately, something breaks off a series of chain reactions the whose devastating effects are amplified a step after another, from earthquakes to the extreme weather phenomena.
The most striking example of this transformation is almost complete resetting of icy surfaces: slightly less than 3000 years ago the Earth was covered by 30% from a blanket of perpetual snow. Today these are almost entirely disappeared.
And the greatest number of extinctions in the history of the planet has been in the past 1600 years, according to what you read in research. All the fault of man?

The human race has caused, and still is the cause of rapid climatic and environmental changes: the nell'atmosera CO2 has increased by 35% over the past 250 years, the area sown or cemented are now more than 40% of total land and the people have broken through the roof of the 7 billion people.
Over the past 200 years in fact, we put the Earth at a stress much higher than that triggered the last great cataclysm.
But what might be the consequences of all this? Difficile dirlo. Hard to say.
The researchers speculate estizioni mass, radical changes in the species who survive, to adapt to new conditions and massive migrations.
In short, a scene from "The Day After Tomorrow".
To date all appeals to the adoption of a lifestyle with less environmental impact have not been answered: according to scientists by 2025 about 50% of the land will be colonized by humans in some form, and by 2050 the population will around 9 billion people.
"I wish that in 50 or 100 years the world was still like today, if not a bit 'better," says the scientist to the media.
"We are at a crossroads, and unless we change something, now, we will leave a very bad future for coming generations."… After a few steps of the research seem a little excessive ...
