As the human race gallops toward adding 2 to 3 billion within the next 40 years, and the USA expects to add 138 million by mid century-no one will speak of the consequences. The eminent population scientist Dr. Paul Ehrlich said, "All causes are lost causes without limiting human population."

"There are three, and only three, ways that human population growth can be reduced to zero or made negative, if that is necessary for our species to survive," said Brent.

They are:

1. By war, with or without weapons of mass destruction, starvation, disease, rape, murder, ethnic cleansing, concentration camps, and other horrors beyond the imagination, when humanity has exceeded the carrying capacity of the Earth. At this point it is not necessary to define or explain what is meant by the "carrying capacity of the Earth" as it is not essential to the analysis set forth in this essay.
2. By the voluntary action of all of humanity prior to the human population exceeding the carrying capacity of the Earth. If any group or even if a single-family failed to control its population the entire program would fail. For example, Mr. Justice Scalia had nine children and if each of those had nine and if in each generation each offspring had nine, then in just 11 generations about 31 billion Scalias would live on the planet. That is the power of compound growth.
3. By coercive population control prior to the human population exceeding the carrying capacity of the Earth.
