The world population reached 8 billion in mid-November 2022, and it was only 2.5 billion in 1950. The world's population is expected to increase by about 30 billion people in the next 9 years to reach 7.2050 billion in 10.
The projected peak in the world's human population could reach 4.2 billion in the mid-<>s, the United Nations said in a report last year. Once demographic inflation is overcome, the pressure on nature and climate will recede.
