According to the UN estimates, on Tuesday the world’s population is projected to reach 8 billion people. This is considered a milestone in human development by the UN. United Nations’ most recent estimates suggest the world’s population may reach 8.5 billion people in 2030, 9.7 billion in 2050, and 10.4 billion in 2100.
While it took 12 years for the world’s population to increase from 7 to 8 billion people, it will take roughly 15 years—until 2037—for it to reach 9 billion people, indicating that the population’s overall growth rate is slowing.
In just eight nations—Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines, and Tanzania—will be concentrated more than half of the predicted rise in the world’s population by the year 2050. The order of the greatest countries in the world will change as a result of divergent growth rates.
The nations with the lowest incomes per capita also tend to have the highest fertility rates.
Rising per capita incomes are the primary cause of unsustainable patterns of production and consumption, even though population growth magnifies the environmental effects of economic development.
According to the UN, reducing unsustainable patterns of production and consumption is essential to achieving the SDGs and the goals of the Paris Agreement to limit global temperature rise.
