The emergence of agriculture and its sustainable influences on the development of mankind

The beginnings of human agriculture can be dated to a period of about 12,000 to 9,000 years ago. In this significant period, which is considered the first great revolution in the history of human civilization, the human species began to gradually break away from a purely hunting and collecting way of life in order toto develop the first forms of agriculture and animal husbandry. This fundamental change in human life was first in the regions of the so-called fertile crescent, a fertile zone in the Middle East that stretched across the territory of present-day Syria, Iraq, Israel, Jordan and Palestine. This room was through fertile soils, water sources andFavorable climatic conditions that enabled early people to try out the first agricultural techniques. Interestingly, similar agricultural practices developed independently in other parts of the world, especially Central America and China, suggesting that these developments in several regions are parallel and almosttook place at the same time. While there is no concrete archaeological evidence to date these early cultures have undergone direct exchange or conscious learning, the assumption is that any civilization has to develop agriculture as a response to a larger, fundamental force that determines the entire ecosystem of our planet.influenced. This driving force can be explained by the global warming that began after the last ice age and fundamentally changed the environmental conditions on earth.

The climatic conditions during the Ice Age

During the last ice age, the climatic conditions on earth were extremely extreme. Large parts of the northern hemisphere were covered by mighty ice sheets that stretched across wide land and transformed the landscape into an inhospitable, cold and often hostile environment. The climate was significantly colder than today, and the temperatures in some cases fellRegions on values that were difficult to cope with for the survival of the flora and fauna. In addition to the low temperature, the world was also characterized by a pronounced drought at that time, which significantly restricted plant growth. In areas like Ireland, which is now known for its humid and mild climatic conditions, the cold is often high in moistureAssociated, but in reality the ice age cold was mainly characterized by drought. At low temperatures, the evaporation of water is greatly reduced, resulting in less cloud formation and thus less precipitation. This world was characterized by a combination of extreme cold and drought during the Ice Age, which made it difficult to survive animal and plant species.Plants could only grow under extremely difficult conditions, and wildlife was forced to adapt to these adverse environmental conditions or to seek refuge in the few remaining warmer and wetter areas. Under these extreme environmental conditions, agricultural use of the soil was almost impossible because the risks for cultivation and harvesting were too highwere. It was simply too dangerous to rely exclusively on a single land section when it came to energy and food production, since environmental disasters and climatic fluctuations massively endangered the security of supply.

Climate change and the resulting environmental change

With the end of the Ice Age, which lasted several thousand years, a gradual shift to warmer and humid climate conditions began. The ice sheets were melting, temperatures were rising and the global environment changed fundamentally. This climate change led to a dramatic increase in biodiversity and created the conditions for aSustainable use of environmental resources. The world became more life-friendly, which led to people settled in places that were previously uninhabitable or hardly usable. It is important to understand that this climate change was not a sudden process, but took place over a period of several thousands of years. During this long transitional period, people livedStill mainly as hunters and collectors, searching for wildlife and wild plants to secure their livelihood. At the same time, they began to try the first attempts to grow plants and domesticate animals to put their food security on a more stable basis. This transitional phase, in which agriculture was only a sideline, lastedProbably many millennia. Only with the improvement of agricultural techniques, the development of more efficient cultivation methods and the targeted domestication of animals, agricultural production began to play a significant role in human survival. The ability to produce food systematically and reliably marked a crucial turning point inof human history.

The transition from hunters and collectors to sedentary farmers

The development of agriculture led to people gradually refraining from nomadic lifestyles and settled in permanent settlements. For early humanity, finding plants that were both nutrient-rich and easy to cultivate was crucial. It was shown that cereals such as wheat, barley or corn were particularly goodwere suitable because they grew relatively easily in nature, delivered high yields and could be harvested within a short time after sowing. The evolution of grain also played a crucial role: It is self-pollinating, which means it is genetically stable and grows reliably without being dependent on crossings. These properties were crucialFor nomadic hunters to gradually settled, as they provided a reliable and easily accessible source of food. With the increasing domestication of animals that provided important proteins and the further development of agricultural techniques, the fertility of the planet overall increased. It was expected that the human population would be rapidlywould grow. But surprisingly, this growth was initially much slower than expected, which is due to the high risks and uncertainties in early agriculture.

Challenges and risks of early agriculture

The first millennia of the sedentary lifestyle was an enormous burden for people. As they began to live in solid settlements and grow food in a targeted manner, they were confronted with a multitude of new challenges at the same time. The diseases that were transmitted by the proximity to domesticated animals were particularly serious. These animal diseases likeFlu, measles, smallpox, typhoid and other epidemics spread quickly and claimed countless lives. The transfer of pathogens from animals to humans was a completely new phenomenon, against which the human immune systems had not yet developed defense mechanisms. The first millennia after the introduction of agriculture were characterized by acatastrophic mortality, which significantly slowed down population growth. Humanity was still unable to effectively defend itself against these microscopic invaders, which led to a long time of struggle for survival. It took many generations of evolution to recognize and ward off these pathogens for the human immune system. hencethe domestication of the animals was also a source of great danger and the basis for the development of a more resistant immune system that gradually made people more resistant to diseases.

Demographic change and the development of immunity

According to estimates by scientists from antiquity, the world population was around four million people around 12,000 years ago. Over the next five millennia, during which agricultural techniques were spreading and societies became more complex, the world population grew only slowly. up to about 5000 years before our timeline, theThe number of people grew to around five million, with the limitation of this growth primarily due to the devastating pandemics and diseases that had arisen from close animal husbandry and the poor hygienic conditions. The early farmers’ immune system was not yet prepared for the multitude of new pathogens that weredomesticated animals were transferred to humans. It took many generations of evolution to become more effective and the human defense system to become more effective and the population to become more resistant to these diseases. Through natural selection and transmission of genetic defense mechanisms, survival codes developed that enabled the human immune system to intruderto recognize and defend. With time, around 5000 BC, the population began to grow significantly. The improved agricultural techniques, increasing immunity and better hygiene helped people’s survival be facilitated. At that time, the world population was estimated at around 100 million people, which within just 5000 years was onemeant twenty-fold increase and reflected the enormous advances in human development.
