"When a population exceeds the long term carrying capacity of its environment, also known as overshoot, then famine and disease tend to reduce the size of that population." - Wikipeida Encyclopedia.

Anyone know what the current estimates of how many humans the Earth can sustain? Then you will ask me to clarify, "what is sustain"? Quality of life.. how is this measured. So I do mean, at what point does the human population overwhelm the world's resources, generally speaking. (current view)?


Predict the "end of science" at your peril!

Oy. Estimate numbers. Estimate numbers.

From what I researched; two billion (2,000,000,000) humans.
Nominal: two-thirds (2/3rds) of six billion (6,000,000,000) less than now.
That means four billion (4,000,000,000) humans have got to Go.
They (the Religious) must Go, and must Go quickly, or the War(s) will never end.
Nominal: four billion (4,000,000,000) is the Religious population number.
The same are the Religious humans: them which destroy the earth;
They must Go! Go!

"The Earth's limited supply of natural resources will only be able to sustain 2 billion humans by 2100, bad news for a world that already feeds 6 billion. The optimum human population, or carrying capacity, for the U.S. is projected to be 200 million, which is millions fewer than the current population. Disappearing stocks of fertile land, fresh water, fossil fuel energy, plants and animal life will control human population the old-fashioned way -through starvation and disease -if we cannot reduce our numbers voluntarily. Maximum Global Population Estimates: Each of these assumes that the current depletion of fossil fuel reserves has continued to completion. No fossil fuels are left, except possibly for a small stock, priced high, and used for limited durable uses such as new plastic production and for some pharmaceuticals;

1. Everyone at the current U.S. standard of living and with all the health, nutrition, personal dignity and freedom that most Americans currently enjoy. 2 billion (2,000,000,000)
2. Everyone at the same affluence level as in 1, but with few restrictions on commerce, pollution, land use, personal behavior (within current law), etc. Basically a libertarian, laissez faire economy, with only limited environmental restrictions. This points out that there is a population price to pay for the current American way of commerce. 0.5 billion (500,000,000)
3. Everyone at the same affluence as indicated in 1, but with many and onerous restrictions on freedoms relative to behaviors leading to environmental degradation. In order to accommodate population levels greater than 2 billion, restrictions such as the following would have to be instituted: Massive recycling. Driving restrictions (gasoline rationing, fuel rationing even to mass transit systems). Restrictions on the transport of food (food transported no more than 100 miles for example to its point of retail sales). Prohibitions against cutting of trees on one's property. Limitations on the burning of fossil fuels in order to save these complex molecules for more valuable or durable uses, such as in the manufacture of plastics and pharmaceuticals. Limitations on the areas of open spaces that can be converted to renewable energy power plants, such as solar thermal, solar photovoltaic, and wind energy systems. This latter results from the need to preserve natural areas for atmospheric oxygen generation and food growing. Of course many rooftops can accept solar energy systems and this scenario basically assumes a nearly complete saturation of coverage of roof tops and covers over parking lots for solar energy production. 4 billion (4,000,000,000)
4. Only people in the U.S. and Europe at current level of affluence. Everyone else at the current prosperity level of Mexico. 6 billion (6,000,000,000)
5. Everyone in the world at Mexico's current prosperity level. 20 billion (20,000,000,000)
6. Everyone in the world at the current 'prosperity' level of Northwest Africa. 40 billion (40,000,000,000)"

Oy. Expedient solution. Expedient solution.

Blessed are the dead (the Religious) which die in the Lord from henceforth:
Yea, saith the Spirit,
that they may rest from their labours; and their works do follow them.

The prophets (physicists), and the saints (scientists),
shouldest destroy them which destroy the earth.

Racetrack solution;
Dig, rock, and roll.

Devices which escape the Second Law of Thermodynamics would supply abundant clean electrical energy as they absorb an equivalent amount of heat resulting in no net change in the energy balance as electrical energy turns into heat during use. This is Prepetual Motion of the Second kind where energy is not created or destroyed. Energy in this loop can be used to recycle material waste. A large world population can live in abundance beyond the material living standards of the present most materially well provided regions when / if these machines emerge. I started the topic "diode array nanotech clean abundandant energy" which explores how an array of C60 anode diodes in consistent alignment parallel that rectifies and aggregates Johnson noise may one possible machine of this type.
