The Negative Factors of Overpopulation

Studies have shown that there are some 9 billion people on Earth by 2050. The United States does not seem to have such a world, but there are other countries that demonstrate its abilities. Over the past several hundred years population growth has grown rapidly due to new technologies aimed at improving the lives of all. Overpopulation can have a negative impact on the planet and may affect our daily lives as well. Overpopulation and the negative factor that it brings can be very harmful to the planet.

In some cases, biological factors may interfere with the function of abiotic factors. Excessive population of species affects abiotic factors and may adversely affect other species. Even the smallest organisms like phytoplankton can destroy ecosystems if overpopulation is allowed. This can be seen in "flowers of brown algae". There, too many algae accumulate on the water, prevent sunlight from reaching the lower area, effectively kill all life in the water. On land, when the canopy grows over a large area, a similar situation can be seen, effectively preventing the sun from reaching the underlying plants.

According to the World Health Organization (WHO), overpopulation is one of the main causes of rapid emergence and the emergence of human diseases. Overpopulation worsens many environmental and social factors such as pollution, malnutrition, overcrowded living environment, lack of medical care, making it easier for poor communities to be exposed to infectious diseases. Diseases such as tuberculosis, malaria, HIV, dysentery, etc. will spread rapidly in the over-populated areas. In population-rich areas, recent environmental protection policies allow people to produce more food, invest more cheaply and use agricultural practices to not invade the surrounding land. This resulted in intensive agriculture, resulting in depletion of soil fertility, re-emergence of parasites, emergence of new parasites, loss of ecosystems, water pollution, and a decrease in biodiversity.
