People have destroyed the world since the Stone Age

People have ruined the world since the Stone Age: study finds that agriculture has affected nearly half the land mass of the earth, 4,000 years ago

  • A major study looked at global land use between 10,000 and 170 years ago
  • 4000 years ago, agriculture had more than 40 percent of the land surface of the earth
  • Reveals people cultivated land 1000 years earlier than previously thought

Humans have been damaging the earth for more than 4,000 years and are leaving an indelible impression on the planet.

A major study looked at the global use of land between 10,000 and 170 years ago and discovered that the first recorded evidence of people coincided with the advent of agriculture.

The findings reveal that hunter-gatherers and farmers & # 39; major changes & # 39; on the planet and prove that the footprint of man goes deeper than the Anthropocene.

A total of 255 respondents completed more than 700 regional questionnaires, who provided the information for the study. The global data set revealed that hunter-gatherers and farmers & # 39; important changes & # 39; affixed to the planet

The findings show that the changing cultivation and pastoral area had already affected over 40 percent of the Earth's land surface 4000 years ago.

It turned out that cultivating land 2000 years ago was common on most of the planet, which contradicted earlier research and revealed that people cultivated land 1000 years earlier than expected.

The study, published in the journal Science, relied on a crowdsourcing drive called the ArchaeoGLOBE Project.

It sent a massive survey to archaeologists around the world whose expertise covered all periods of human history.

A total of 255 respondents completed more than 700 regional questionnaires, who provided the information for the study.

It noticed that the modern brand left on the planet is not unique and goes back thousands of years.

Study co-author Professor Michael Barton at Arizona State University, said: “Understanding how people interact with the environment in the long term is one of the best things we can do to help us understand how people are here. deal with the future. & # 39;

& # 39; We do not start from scratch. We start with a long history. & # 39;

Old people's actions are recorded in different ways in the earth and fossil record and Professor Barton explained that studying their environmental successes and failures gives a better idea of ​​how they can create positive change in the future.

He said the study also has implications for models that scientists use to predict how people will affect the environment in the future.

Accurate predictions are based on a comparison of the present with the past – and the data currently underestimate human impact, the study found.

Dr. co-author Nicolas Gauthier of Arizona State University said: & # 39; We hope it will push the field forward in a way that would not have been possible if everyone had worked in isolation. & # 39;

WHAT IS THE ANTHROPOCENE?

The Anthropocene is the name of a proposed geological era that can soon enter the official geological time scale.

It refers to a time when man has permanently changed the planet.

According to the International Union of Geological Sciences (IUGS), we are officially in the Holocene era, which began 11,700 years ago after the last great ice age.

Some experts claim that we should now change the name to & # 39; Anthropocene & # 39 ;.

This is from anthropo, for & # 39; man & # 39; and cene, for & # 39; new & # 39 ;.

Experts remain divided as to when humanity has caused a lasting impact on the geology of the earth, but seem to have settled at a time near 1950.

The atomic bomb is a popular marker.

Dr. Gary Feinman, anthropology curator at the Field Museum in the US, said: & # 39; Through this crowdsourced data, we can see that there was global environmental impact through land use at least 3,000 years ago.

& # 39; And that means that the idea of ​​considering human impact on the environment as a newer phenomenon is too focused on the recent past.

& # 39; About 12,000 years ago, people were mainly foraging, meaning that they did not treat their environment as intensively as farmers in general.

& # 39; And now we see that 3,000 years ago people in many parts of the world are truly invasive. & # 39;

He added: & # 39; There is such a focus on how the present differs from the past in contemporary science.

& # 39; I think this study provides a check, a counterweight to that, by showing that yes, there have been more accelerated land use changes recently, but people have been doing this for a long time. And the patterns begin 3000 years ago.

& # 39; It shows that the problems we face today are very deeply rooted and that they require more than simple solutions. They cannot be ignored. & # 39;
