Experts have pointed to the extinction of the human race. Experts say that the distance from their natural habitat and environment, less genetic variation and the reduction in the ability to produce children will destroy the human race. When the habitat is so degraded that there are few resources for movement, when the ability to produce offspring is reduced, when the birth rate falls below the death rate, and when genetic resources are limited, the only way is decline. There is extinction.
According to the American scientific journal "Scientific American", Paul Ehrlich, a biologist from Stanford University, USA, published a book called "The Population Bomb" in 1968. More. Half a century later, the nuclear threat has lost its importance. As for overpopulation, twice as many people live on the planet now in comfort and prosperity as in 1968. The population is still growing. , but the rate of increase has halved since 1968. Current population predictions vary, but the general consensus is that it will peak in mid-century and then decline rapidly. Global population size in 2100 may be even lower. In most countries the birth rate is now well below the death rate.
In some countries, the population will soon be half of the current rate. People are now worried about the low population. Mammal species come and go rapidly, flourishing and dying out over millions of years. Fossil records indicate that humans have been around for about 350,000 years or more, but for most of that time the species was rare, so rare that it went extinct more than once. approached, and thus threatened the extinction of the human race. The present population has grown rapidly from a very small object. The result is that, as a species, humans are remarkably homogenous. Few groups of wild chimpanzees have more genetic variation than the entire human population.
A lack of genetic variation is never good for the survival of a species. Furthermore, decades of decline in human fertility have reduced birth rates due to pollution, stress, and anxiety. For most of human evolution, people lived in isolated groups in open spaces. The habit of living in cities, practically on top of each other i.e. in apartments or blocks, is a recent habit. Another reason for population decline is economic. Politicians are constantly striving for economic growth, but this is not sustainable in a world where resources are limited. Humans already occupy 25 to 40 percent of primary productivity. Human economic development efforts can have detrimental effects on millions of other species on the planet.
People today have to work harder to maintain a standard of living than their ancestors did, and the fact is that economic productivity has stagnated or declined globally over the past 20 years. It may be that people are ceasing to have children, or that their ability to have children has declined. Another factor in the shrinking population is women's economic, reproductive, and political independence. With health care, women are reluctant to have more children but to have fewer children is to shrink the population.
The most dangerous threat to mankind is something called 'extinction debt', that is, there comes a time in the development of any species, even if it is spreading, when extinction will become inevitable. No matter what he does to stop it. The cause of extinction is usually a delayed reaction to the loss of the rumen.
