Today is that inauspicious day. Though it is a rough estimate at best (Cosmic Log: “7 billion people? How do they know?”) – I would think there are thousands more not counted for various reasons.
“Our number’s up, and that could be a procreation-led disaster”, The Age. Opinion piece saying that there needs to be marketing campaigns to persuade women to have fewer children. (Best comment: “Paradoxically our species is advanced enough to foretell our own demise, yet stupid enough to do nothing to prevent it.”)
Time magazine has a special section, The World at 7 Billion, devoted to population issues.
The graph below, from an article at ABC news, shows how the population has increased alarmingly since 1850 when the Industrial Revolution was underway, and jumped even more since 1950, with shorter periods of time between each extra billion. Worldometers has a page of data about population growth.
- 1804: 1 billion
- 1927: 2 billion
- 1960: 3 billion
- 1975: 4 billion
- 1987: 5 billion
- 1999: 6 billion
- 2011: 7 billion
- 2027: 8 billion (estimated)
