Birth Rate = Death Rate
When the birth rate is the same as the death rate, the world will be in equilibrium between humans and nature.
ZPG Movement
In the late 1960s ZPG became a prominent political movement in the U.S. and parts of Europe, with strong links to environmentalism and feminism. Yale University was a stronghold of the ZPG activists who believed “that a constantly increasing population is responsible for many of our problems: pollution, violence, loss of values and of individual privacy.”[10] Founding fathers of the movement were Paul Ehrlich, author of The Population Bomb, Richard Bowers, a Connecticut lawyer, and Professor Charles Lee Remington. Humans were already passing the point of equilibrium in the 1960s.
Who's responsible for this?
The responsibility does not fall strictly on women. For instance realizing back in the 70s that too many humans on the planet would be more than the planet could support, I had a vasectomy. One of the smartest moves of my life and my wife thanked me later when she saw that the planet was heading for Global Warming Climate Change/Crisis.
Who should be responsible
China and the USA are responsible for 41% of the global greenhouse emissions
- Chine 27% divided by 1.4 billion people equals 1.92 to the -8 exponentially per person
- USA 14% divided by 330 million equals 4,24 to the -8 exponentially per person
On a per person basis the USA is 2.2 times more contributors to Greenhouse emissions than China
