population explosion
Quick Summary
The term "population explosion" refers to a rapid increase in the number of individuals within a biological population, particularly the significant growth in human numbers seen in recent times. This surge is largely due to increased survival rates and exponential population growth.1
Historically, human population growth has occurred in waves. The first major leap followed the agricultural revolution, and a second, much faster explosion began with the Industrial Revolution. While global population growth rates peaked in the late 1980s, the world population reached 8 billion in 2022 and is projected to continue growing, though at a slower pace. This growth is influenced by fertility, mortality, and migration rates. Concerns exist about the environmental and societal impacts of this continued growth.23456
