Every person emits two tons of carbon dioxide a year through eating according to a Spanish study published November 2, 2010 by the Spanish Foundation for Science and Technology.
Summary: Every person emits the equivalent of approximately two tons of carbon dioxide a year from the time food is produced to when the human body excretes it, representing more than 20 percent of total yearly emissions. That is what a study by researchers in Spain says, confirming for the first time that human excrement contributes to water pollution, primarily with nitrogen and phosphorus.
This was a fiddly and precocious research which I suspect was the product of a Spanish crop developed in Leuven. If this data is contrasted with current ideas that World population will add 2 billion people by 2050, increasing by one billion each 12 or so years then despite being over 5 years old the article here offers a balanced consideration of some pretty unreal rationality.
World pop (population) - I've gone to Wikipedia here because it offers research fart based in scientifically gathered data which made significant efforts to minimise its production of methane. Thus...
The median estimate for future growth sees World population reaching 8.6 billion in 2030, 9.8 billion in 2050 and 11.2 billion by 2100 assuming a continuing decrease in average fertility rate from 2.5 births per woman in 2010–2015 to 2.2 in 2045–2050 and to 2.0 in 2095–2100, according to the medium-variant projection. With longevity trending towards uniform and stable values worldwide, the main driver of future population growth is the evolution fertility.
However - simple review of nuber s indicates that a population of 3 billion in 1960, doubled in 40 years. There were 6 million people in 2000. In 2020 there will be 8 billion people.
Here we are then. 40 years to increase population by 3 billion (1960-2000)- to double it, followed by 20 years to increase population by 2 billion (2000-2020). There are people who believe that population can stabilize and amongst them are those who think it will.
In 2040, there will be 10 billion people. By 2080 there will be no fewer than 20 billion people and very probably actually near to 24-25 billion.
In 2120 there will be........... 50 billion people on Earth.
Someone born today and living until 100 years of age will be alive when there are 50 billion people on Earth. Isn't that and this entirely fascinating.
Returning to the Spanish research assessment, they are of the opinion, 'As regards emissions, "human excrements have a net null effect on global warming, as they are offset by carbon fixation in photosynthesis. As a result, they do not contribute to increasing the concentration of CO2 in the atmosphere." FECYT - Spanish Foundation for Science and Technology
Lovely, yes........... no. This is the closed loop theory of null contributions by people. It is the scientific and political sanity clause which allows a philosophical approach to ignoring over-population. There are too many people and no way to halt or cease procreation. How absurd is that. We are absurd.
If there were no people then they would not each be contributing two tons of CO2 per year to the climate. The closed loop logic is detrimental rhetoric by very clever morons. Yes, they are oxymorons.
The global population should collapse around 2075 as migration becomes unsustainable.
The information above is the precursor to the rather simple reality of broad legal QUANTUM . Intentionally or otherwise, the economic inflation target is an economic means to ensure that what there is goes around to meet the needs of population growth. Money being money then of course the practice is fraught with idelible humanities failings and frailty. However, the target should ensure that what is termed GDP per capita, grows sufficiently to fund each persons needs and rights.
Here's the fun bit. GDP should double each 40 years. There is an argument that growth needs to be by power three rather than two but that stems from humanities idelible failings and frailties. Inflation is the economic mechanism which provides for population growth. Very few economists understand that this* and none ever discuss it in relevant terms.
