Population growth
The document discusses historical population growth, noting that early populations were small due to limited food and low life expectancy. Significant growth began around 9,000 years ago with agricultural developments, and accelerated from 1800 to the present day, reaching 7 billion people. Factors such as improved life expectancy and societal changes since the 19th century have contributed to this growth.
