On November 15, the United Nations announced that the world’s population reached 8 billion on this day, a milestone in the history of human development.
In recent years, improvements in public health, nutrition, hygiene, and medicine have led to a gradual increase in human life expectancy, which has contributed to global population growth.
In addition, high fertility rates in some countries have contributed to rapid population growth.
However, it is worth noting that it took about 12 years for the global population to grow from 7 billion to 8 billion.
And it will take about 15 years to reach 9 billion by 2037, meaning that the overall global population growth is actually slowing down.
The UN also says that over time, global population growth is increasingly concentrated in the world’s poorest countries, most of which are located in sub-Saharan Africa.
And while population growth is not as rapid in countries with higher per capita incomes, it is where per capita consumption of material resources and greenhouse gas emissions are highest.
