Globally, the per capita growth rate of the human population has been declining since its increase in 1962 and 1963, which was 2.20%. In 2009, the estimated annual growth rate was 1.1%. Currently, the world population stands at approximately 7,211,021,348 people, an increase of 4 billion since the 1960s. Most of this growth comes from very poor countries. Increasing human population can lead to problems such as pollution and traffic jams; these problems could be solved or worsened by technological and economic changes. Over the past 100 years, we have seen a rapid increase in population due to medical advancements and massive increases in agricultural productivity. The main fear is that a high population will strain natural resources, food supplies, etc. Population growth has major advantages and disadvantages for the world we live in. Population growth is the increase in the number of people who inhabit a territory or state with the equation of (BD) + (IE) where (B) is births, (D) is deaths, (I) is the rate immigration and (E) is the emigration rate. Population growth has a biological and environmental effect on our planet Earth. On the other hand, population growth can have a positive impact on the economy. Much of the population growth comes from countries with high poverty rates. Many people suggest that this is because poor people often want to have more children because children represent wealth, provide work, and can help out when parents age. Another major reason for the high number of births in very poor countries is the lack of protection during sex. Much of our population is living much longer than before thanks to new advances in medicine and technology. This causes humans to live much longer than previous populations...... middle of paper ......are on the brink of extinction due to overculture and habitat loss. One of the major problems we cause is overexploitation. We are exploiting oil, gas and forests at a high rate. The problem is that all of these things are non-renewable resources and have an impact on the environment and biodiversity. So how can we solve all these problems we face as a world? One solution could be to establish a family planning system so that women can only have one or two children. Individually, as humans, we can reduce our resources, for example by driving less and using fewer goods that are not a total need. Finally, we can improve our education system and increase the graduation rate in the United States and other developed countries. Studies have shown that the higher the graduation rate, the lower the fertility rate. All of these things can help us deal with overpopulation.
