Heimsendaspámenn finna allt til þess að hræða okkur, eða betur sjálfa sig. Fólksfjölgunin eitt hræðsluefnið alla leið frá Maltus. Hitler og hans kónar voru jú líka heimsendaspámeenn og drápu milljónir fólks með köldu blóði til þess jú að bjarga heiminum. Kannski núna þegar veðrir hræðir okkur ekki lengur og nóg af orku þá byjrum við líklega að hræðast fólksfjölgun aftur::

Mjög einkennileg upplag að umræðu um þessa grein. Kannski hefði tekist betur til ef þú hefðir lesið hana Ingimundur?

In 1787, shortly after the close of the Constitutional Convention in Philadelphia, a woman interested in the proceedings approached Benjamin Franklin. "Well, doctor," she asked, "what have we got, a republic or a monarchy?" The venerable champion of American liberty replied, "A republic, madame, if you can keep it."

Jú jú ég las hana, en fyrisögnin kannski misheppnuð. En eins og ég sagði. þið drógust eins og flugur að ljósinu, enn ein heimsendaspáin sem þið ætluðuð að velta ykkur upp úr og njóta eins og hundurinn sem veltir sér upp úr skítnum. Svei mér þá, held að nýja myndin af mér sé að gera mig verri og ónótalegri, áður reyndi ég þó að vera vinalegur eins og í barnamyndinni af mér, ekki að lemja ykkur með sannleikanum við hvert tækifæri. En eins og segir, einhver verður að standa í skítverkunum.

Ég hraðlas þessa grein og mér sýndist höfundur einkum vera að velta fyrir sér áhrifum stöðnunnar í fólksfjölda á efnahagslíf (hagvöxt) í mismunandi ríkjum. Ég nenni ekki að lesa hana aftur til að vera alveg viss, en hvegi sá ég neinar vangaveltur í greininni um mannfjöldavá - hvað þá neinar forspár um neikvæðar afleiðingar fólksfjölgunnar. Greinin sem slík er fremur hlutlaus og bragðlaus á alla kanta, svosem ágæt vangavelta út af fyrir sig en lítt áhugaverð fyrir fólk eins og mig sem trúir því ekki að hagvöxtur sé eftirsóknarverður í sjálfu sér til langframa.

Sem sannar það sem ég sagði, að flestir vilji lesa um að allt sé að ónýtast og eyðileggjast, alveg sama hvað, meira að segja litlu börnin ómagar og til óþurftar. Eða eins og myndin hérna fyrir ofan sýnir, Þjóðverjar í því að fækka mannfólkinu rétt fyrir utan Kief, konur og börn skotin í þúsundatali dag hvern til þess að fækka mannfólkinu.

Ath að í þessari spá er ekki reiknað með orkuskorti og reiknað með að flest okkar hætti að borða kjöt.

The power of population is so superior to the power of the Earth to produce subsistence for man, that premature death must in some shape or other visit the human race."
The late-18th century philosopher Thomas Malthus wrote these ominous words in an essay on what he saw as the dire future of humanity. Humans' unquenchable urge to reproduce, Malthus argued, would ultimately lead us to overpopulate the planet, eat up all its resources and die in a mass famine.
But what is the maximum "power of the Earth to produce subsistence," and when will our numbers push the planet to its limit? More importantly, was Malthus' vision of the future correct?

Earth's capacity
Many scientists think Earth has a maximum carrying capacity of 9 billion to 10 billion people. [How Do You Count 7 Billion People?]
One such scientist, the eminent Harvard University sociobiologist Edward O. Wilson, bases his estimate on calculations of the Earth's available resources. As Wilson pointed out in his book "The Future of Life" (Knopf, 2002), "The constraints of the biosphere are fixed."
Aside from the limited availability of freshwater , there are indeed constraints on the amount of food that Earth can produce, just as Malthus argued more than 200 years ago. Even in the case of maximum efficiency, in which all the grains grown are dedicated to feeding humans (instead of livestock, which is an inefficient way to convert plant energy into food energy), there's still a limit to how far the available quantities can stretch. "If everyone agreed to become vegetarian, leaving little or nothing for livestock, the present 1.4 billion hectares of arable land (3.5 billion acres) would support about 10 billion people," Wilson wrote.
The 3.5 billion acres would produce approximately 2 billion tons of grains annually, he explained. That's enough to feed 10 billion vegetarians, but would only feed 2.5 billion U.S. omnivores, because so much vegetation is dedicated to livestock and poultry in the United States.
So 10 billion people is the uppermost population limit where food is concerned. Because it's extremely unlikely that everyone will agree to stop eating meat, Wilson thinks the maximum carrying capacity of the Earth based on food resources will most likely fall short of 10 billion. [When Will Earth Run Out of Food? ]
According to population biologist Joel Cohen of Columbia University, other environmental factors that limit the Earth's carrying capacity are the nitrogen cycle, available quantities of phosphorus, andatmospheric carbon concentrations , but there is a great amount of uncertainty in the impact of all of these factors. "In truth, no one knows when or at what level peak population will be reached," Cohen told Life's Little Mysteries.
Slowing growth
Fortunately, we may be spared from entering the end-times phase of overpopulation and starvation envisioned by Malthus. According to the United Nations Population Division, the human population will hit 7 billion on or around Oct. 31, and, if its projections are correct, we're en route to a population of 9 billion by 2050, and 10 billion by 2100. However, somewhere on the road between those milestones, scientists think we'll make a U-turn.
UN estimates of global population trends show that families are getting smaller. "Empirical data from 230 countries since 1950 shows that the great majority have fertility declines," said Gerhard Heilig, chief of population estimates and projections section at the UN.
Globally, the fertility rate is falling to the "replacement level" — 2.1 children per woman, the rate at which children replace their parents (and make up for those who die young). If the global fertility rate does indeed reach replacement level by the end of the century, then the human population will stabilize between 9 billion and 10 billion. As far as Earth's capacity is concerned, we'll have gone about as far as we can go, but no farther. Follow Natalie Wolchover on Twitter @nattyover.

I'd like to share a revelation during my time here. It came to me when I tried to classify your species. I realized that you're not actually mammals. Every mammal on this planet instinctively develops a natural equilibrium with the surrounding environment but you humans do not. You move to an area and you multiply and multiply until every natural resource is consumed. The only way you can survive is to spread to another area. There is another organism on this planet that follows the same pattern. Do you know what it is? A virus

 

Good advice is always certain to be ignored, but that's no reason not to give it.

ein spáin segir að árið 2100 verður við 11 milljarðar og komin í globalt getnaðar jafnvægi. Þegar fleira og fleira fólk í t.d. Kína og Indlandi kemst í þægilegt millistéttar líferni, fækkar barneignum þeirra. Sama gerist við menntun kvenna í fátækari löndum, og auknum skilningi fyrir getnaðarvörnum. Og ný tækni mun sjá þessum fjölda fyrir mat og klæði. En hvað er það við þetta topic sem fær menn til að birta ógeðfelda mynd af morði á barni og konu.
Takk fyrir a velja - Haltu n kjafti nstu 4 r.
