A question that interests a considerable number of people from children to the elderly: "How many people on the planet?" Of course, it is impossible to answer with absolute accuracy, because every minute in the world someone is born and someone dies. According to estimates, in 2012 a seven billionth person was born on Earth from the living, therefore, the answer to the question of how many people on the planet now is more than seven billion.
A bit of history
Forty thousand years before our reckoning, about forty billion people were born, and in the 1990s, about fifteen billion. In 1900, there were no more than two billion people on Earth, and in 1950 more than two and a half, in 2005 - more than five. As we can see, the population began to grow rapidly only 120 years ago.
What determines how many people on the planet
A huge number of people died during illnesses and epidemics. For example, from the plague from 1346 to 1352. Bubonic plague, Great pestilence, black death - this is what this terrible disease was called. She destroyed a quarter of the world's population. Blackpox - one hundred out of one hundred thousand people died from it. This disease did not spare anyone. The outbreak stopped only after vaccination. An acute intestinal infection - cholera - claimed the lives of more than forty-three million people. Typhoid, accompanied by a mental disorder amid a fever, claimed more than three million lives. From malaria, tropical fever, up to three million people die each year. More than forty million have passed away from AIDS, the "plague of the twenty-first century" - the second name of the virus. We see how many people on the planet have died and continue to die from various diseases.
Most of the population neglected hygiene procedures until the twentieth century. Consequently, infections developed, weakened immunity, and reduced life expectancy. Only rich people could use soap. Those who nevertheless monitored cleanliness (there were few of them), but did not have the opportunity to purchase soap, used various tinctures on ash and cleanings.
The lack of medicine also affected how many people on planet Earth could live. The antibiotic, the strongest antimicrobial drug, was discovered in 1928 by Alexander Fleming. For this discovery, he received the Nobel Prize. Later antifungal agents and antiviral agents appeared. Today we can go to the pharmacy and buy a lot of medicines, and only a hundred years ago our ancestors could be treated only with herbs, and even then not always.
Medicine has taken a long step forward: operations, organ transplantation, the emergence of various drugs to support the functioning of organs - all this has increased the life expectancy of the population.
During the formation of states there were many wars over the territory. During the Second World War, more than fifty million people died, in the First - more than twenty-five million. In the entire history of the planet, approximately 15,000 wars have passed, and more than three and a half billion people have died.
How many people on the planet depend directly on how many are born. One hundred and fifty years ago, there were seven deaths per ten newborns. With the advent of maternity hospitals and the qualified help of doctors, mortality of newborns has decreased by a thousand times.
All these factors have influenced and continue to affect the number of people on Earth. Scientists predict that by 2050 there will be more than eleven billion people on the planet.
