Two scientists have shown an equation for calculating the time when people began to shape the earth. No one knows exactly when a 10-kilometer-long meteorite fell on Earth. , as well as the day the land where the meteorites fell was called the Yucatan Peninsula. But we know that day was about 65 million years ago.
Days later, the earth became colder and darker, and the number of dinosaurs was declining.The collision has reshaped the life support system on Earth by blowing up large amounts of dust, evaporating huge amounts of water and activating hundreds of earthquakes and volcanic eruptions. This dam is followed by a large number of extinctions marking one of the most famous geologic distributions, between the twilight of the white ape and the dawn of the ancient period. In terms of global impact, humanity seems to be a reflection of that meteorite. They have changed the planet so much that many scientists believe that modern society deserves its own geologic age - The Anthropocene. While no one knows that every day human beings become a force in nature, two scientists believe they have an equation to determine that moment.
This planet has existed for about 4.5 billion years. Over three quarters of that time, the earth has the necessary conditions to support life. "Earth in general is always in a stable state, feedback rings keep things like the atmosphere and temperature at equilibrium throughout the rotation of time," says Owen Gaffney. , a writer and author of the new study published in the Anthropocene Review. During periods of equilibrium, life forms slowly evolve, extinction is rare and biodiversity is constantly rising. And then the meteorite collision struck either the volcanic super-volcanic eruptions, or maybe the earth was half-tilted on its axis. Every disaster changes the atmosphere, temperature, ocean components, and dozens of subsequent chain reactions that determine which species are adaptive enough to survive.
In the year 1700, mankind used about 5% of the earth's surface. In 2000, the area used was 55%
• Human-induced emissions are the cause of the ocean being acidified to nearly the same extent as the Permian extinction that occurred nearly 300 million years ago.
• With the estimate lowered several times, the current extinction level is 10 times greater than the geologic equilibrium period.
"You can easily list a long list of things people have done to change the planet, but it will soon become boring," said Erle Ellis, an ecologist from the University of California, Berkeley. Maryland. In his words, the question is whether the studies actually determine when human activity begins to control the biosphere.
Ellies is a member of the team of amateur activities whose mission is to make preliminary assessments that ultimately define the age of birth as an official geologic time. Validating this era will be a great responsibility, and also a controversial issue among earth scientists. The question is whether human life has no change in life on earth. Still, according to Ellis, "There is absolutely no controversy here."
The real issues that are debated in the group are quite practical, including: Can all human activities be included in a trace of geology big enough for biologists in futures research? And for what reason should we name a rock that has not yet formed? "Given a new era at the moment, there really is not much of a benefit for stratigraphers and geologists in the study of layers of rock to understand the course of its formation." Ellis.Co-authored with Gaffney, is the atmospheric scientist, Will Steffen of the Australian National University, and a member of the humanities group. In a new study of the couple, they describe an equation that compares the effects of a few hundred years with the basics of the New Tan period, a geologic period starting 11,700 years ago. . "We have seen comprehensively all of the important motor processes and their speed of change," Gaffney said. For most of the time, everything on Earth was in equilibrium - and was held steady by the energies of the sun's activity, the tilt of 26.5 degrees on the earth's axis, and the absence of The stones are about the size of the islands falling from the universe.
According to their calculations, the time when human activity completely overshadowed the main impact of the sun, the earth and the wandering meteors with the shaping of life on earth was about five 1950. "This coincided with the first nuclear bombs, and they themselves generated a radioactive amount that could be traced to atmospheric gourds, which could be found in deep pools. ". - According to Gaffney. These bombs were not the first things to be considered after the war. The 1950s were marked by the rapid acceleration of many scientists, the period when the outbreak of the middle class led to a spike in global GDP, the land being used for agriculture, the construction of dams, the possession of personal vehicles, global travel and other notable features of the Earth's consumption of resources. Steffen and Gaffney's equations only add weight to the argument that the age of birth has begun in the era of color TVs.
Ellies is one of the minority members of the members of the League of Young Philanthropists who believe that the roots of this era lie deep in the history of humanity. "The industrial revolution happened so long before 1950," he said, "Humanity should also consider the unintended effects of agricultural activity that began thousands of years ago. before the biosphere. "
