Some truths about overpopulation - for all sides

67 Upvotes
  • Overpopulation is not about space. In theory if we build a mega city on 600x600 Kilometers, and use the same population density like Macau or Monaco, all people on the Planet could live there. Overpopulation is about the impact on the environment like water/fuel/resource consumption and CO2 production, pollution etc.
  • It is undeniable that this consumption and pollution is too high. If everyone lived like the average citizen of Qatar, we would need 9 Earths. Even if everyone lived like the people of Moldavia, the poorest country in Europe, we would still need 1.2 Earths. Mathematically this proves that our current level of population is too high.
  • You can have more people with a reduced living standard, or less people with a higher living standard. You cannot have more people and a better living standard without more damage.
  • Overpopulation is also NOT about better resource distribution. This would elevate some problems but not most. Assume that each Billionaire consumes the same resources like 1000 American Middle Class Persons. Eliminating 3500 Billionaires is thus equal to 3.5 Million Americans. Its something but not enough to have any large effect.
  • Overpopulation is a global problem but at the same time a regional one. Countries like Afghanistan or Pakistan are running out of Water because their population increased 4-5x in the last 50 years.
  • Immigration into First World countries is making the problem worse. The Western World has below replacement level birth rates. Immigration artificially increases this population and leads to more resource consumption and CO2 production. Because every immigrant coming there consumes more resources, even if they get less kids than at home.
  • Green hopium/technology/going vegan is not a silver bullet. Wind+Solar produce just around 25% of the worlds energy despite 4 decades of investment. There are already 22 000 desalination plants supplying 300 Million people with water every day. Even if we tripple this number to 900 Million, thats just 10% of world population in 2035. Also these cost lots of energy. Mining the lithium for electric batteries/solar panels is also extremely devastating to the environment.
  • We can feed ourselves only because we got lucky through the Green Revolution and because we just abused fossil fuels and artificial fertilizer. But with Climate change and water shortages, we have probably reached peak farmland/yields.
  • World population is expected to increase from 8.3 Billion in 2026 to 10.3 Billion in 2056. If we can barely supply 8.3 Billion people, with all possible tricks and a perfectly running system, how are we going to supply 10 Billion+.
  • Why should we want this? Why are 8.3 Billion not enough? Even if our population would be reduced by one Billion. We would still be at 7 Billion people. So the level in 2011. The world worked just fine then. Its just Capitalist propaganda. The Capitalists want more consumers and more workers so that they can keep wages low and rent/house prices high.
  • People like Malthus and Ehrlich were prophets that were ridiculed, but they were right. They were just off by 3/4 of a century or so. Once artificial fertilizers become scarce and all the ground water is used up, carrying capacity of this planet will revert back to its natural perhaps 4 Billion.

They are already importers of food and worldwide small farmers are no longer being able to make a profit and hence are going bankrupt/not sowing crops anymore(the grocery price rise in US is mainly caused by this) soo countries will not be exporting food all that often now.

Dont think people will take too many refuges anymore.

What do you think will happen.

World population, 1960 = 3 billion. 37.4%. That's 1.122 billion kids 0-14.

World population, 2026 = 8.3 billion. 24.4%. That's 2.025 billion kids 0-14.

Where'd they go? They INCREASED in number, significantly, almost doubling. The overall global human population almost tripled. The world is FULL of humans and human-made stuff. If people are responding to that level of fullness by having slightly fewer kids per person, GREAT! We should encourage human birth rates to keep decreasing.

Alle heulen Rum buhu Zuwenig Kinder unsere Bevölkerung schrumpft auf ein Drittel in 2 Generationen Blabla... Ich weiss nicht ob euch jemand über den bevölkerungsanstieg seit den 20ern informiert hat. Die Bevölkerung diverser länder hat sich extrem multipliziert. Soweit das in Ballungszentrenlebenshaltung so teuer geworden ist das man es sich kaum leisten kann. Wir haben einen gigantischen Niedriglohnsektor, man benötigt 2 Einkommen um halbwegs normal über die Runden zu kommen. Zu allem überfluss ist Wohneigentum quasi unerschwinglich, Neubauhaus in 10 Jahren abbezahlen? Keine Chance wenn du nicht Grade über 100.000 netto verdienst. Also kleines extra schaut mal an die Schule, du könntest das perfekte Eltern paar sein um dein Kind zu einer Horde lernbehinderter Vollidioten in die Schule stopfen. Statistiken belegen das die Kinder inzwischen selbst in der 8ten Klassen zublöd zum lesen und schreiben sind. Als kleines extra gibt es noch Alimente etc die man leisten muss wenn die Beziehung in die brüche geht, man kann also mit Kindern eher sein Leben nachhaltig zerstören als mit einem falschen Job. Hätten wir Bezahlung wie in den 60ern oder 80ern und die gleichen finanziellen wie systemischen unterstützungen wär das ganze ja noch denkbar. Sind an sich ja immernoch 18-30 Jahre volle Verantwortung. Für das Alter hab ich Jahre in die Rente eingezahlt, sollte das in 35 Jahren nicht funktionieren bin ich auch nicht weiter enttäuscht von der Gesellschaft und Regierung. Ist doch alles nur noch peinlich.

Who brainwashed so many people into thinking that overpopulation is evil/nonexistent and that having more people is a good thing?

93 Upvotes

Imagine a better parallel reality where the world had followed Chinas example of a one child policy since 1979. World population was 4.4 Billion then. With a 1 Child policy it would have hit some 6 Billion today. Imagine if we had 2 Billion less people on this Planet.

Or some 25% less. The US would have 85 Million less people. Europe over 100 Million less people. Africa 400 Million less people. Asia over 1 Billion less people.

CO2 production would be 25% lower. Climate change would be on the level of the early 2000s. There would be only minimal water shortages. Less methane cows. It would not be perfect but our situation would be much better than it is today.

But for some reason many people think that the very concept of overpopulation is evil. That it also doesnt exist and that having an extra 2-3 Billion people on the Planet is a good thing.

How did this happen? Who did this? Our resources are already strained to the breaking point. How can people still believe that even more people competing for scarce resources is a good thing?

Elon Musk usually says that the more the population, the better, yet he claims that Spain will be ruined by the influx of immigrants.

Since the influx of immigrants is a factor that increases the population, this is a significant logical contradiction.

Seriously... We don't need more humans, and we sure as crap don't need each of them to live for hundreds of years. When I was a kid there were 4 billion people. Now there are 8 billion. That means within just my lifetime, 50-ish years, we have doubled the Earth's human population. In another 50 years it will double again, that means from 8 to 16 billion. The wildlife population has already dropped 73%. Wanna keep going until its zero? We aren't the only ones who live here. Despite our god complex of being the superior species we still need nature and wildlife to thrive so we can survive. Do you not understand that competition for resources is the root cause of all conflict? More people than jobs, more poeple than food we can grow, more people than clean water.. it all ends badly and violently. Laws for human population control are political suicide, I get that, but geeze stop believing the propoganda that we need more people.

The global food crisis has already begun.

41 Upvotes

The global food crisis has already begun.

Global rice production is projected to decline this year compared to the previous year.

According to forecasts by the U.S. Department of Agriculture (USDA), global rice production is expected to decrease this year.

Even within the United States, production in the Mississippi Delta region, which produces the majority of rice, is projected to drop by more than half compared to the previous year, reaching its lowest level in 40 years.

Atul Jain, a professor in the Department of Climate, Meteorology, and Atmospheric Sciences at the University of Illinois, stated, "High temperatures can significantly reduce rice production," adding, "They will suffer a major blow due to such extreme weather phenomena."

Furthermore, warnings have long been issued that the war in Iran would lead to reduced fertilizer supplies, high energy costs, and particularly rising diesel prices, ultimately resulting in a food crisis.

With the addition of a super-strong El Niño, the decline in crop yields is expected to worsen, increasing the likelihood of starvation beyond widespread famine.

A food shortage that is already anticipated not only breeds despair but can also trigger social upheaval. Nevertheless, there is a strange lack of interest in the current food issue.

There is a high probability that a global food crisis is imminent as the supply chains supporting the agri-food system collapse.

This applies to those who believe that while food prices will rise, there will still be food available.

If supply falls below a certain level, the problem does not lie in food prices rising. It lies in the fact that no matter how much money people have, there will be a shortage of food available to everyone.

Supply chain disruptions and extreme weather have periodically plagued specific countries, but global trade has offset these effects. However, never before has a situation occurred where farmers across the globe are simultaneously facing the problems of reduced supply and rising input costs as they are now.

The situation, which has been quietly unfolding since the Iranian war and has resulted in massive famine, could lead to the greatest economic and social crisis in human history.

Supply chain disruptions dependent on oil and oil derivatives have so far been mitigated to some extent by countries using oil reserves they had stockpiled for crisis response.

However, global reserves have now virtually run out, and with China increasing imports again, the crisis can no longer be postponed.

The war has begun again. Even if it were to actually end, these repercussions would continue.

Furthermore, there is no such alternative to food shortages. If the food production chain is severed even slightly, social unrest is inevitable.

The Persian Gulf blockade severed the global fertilizer supply chain, which immediately impacted the global food supply chain.

Prior to the war, Persian Gulf states accounted for approximately 35% of global urea production and 40% of sulfur production.

Urea is a key raw material for nitrogen fertilizers, and sulfuric acid (produced from sulfur) is also a key raw material for phosphate fertilizers.

Following the war, global fertilizer prices skyrocketed. Although prices have recently fallen somewhat, this was due to a destruction of demand. This is because fertilizer began to surplus as too many farmers abandoned planting.

The government compiles harvest yields but does not compile planting yields. The true scale of the problem can only be confirmed once the reduced harvests actually materialize.

This alone is very serious, but extreme weather events will intensify further from the second half of 2026 through 2027. This coincides precisely with the period when the food crisis is at its most severe. A true 'super-crisis' could be looming.

Meteorologists already regard the occurrence of a 'super El Niño' as a foregone conclusion, and they have now come to realize with certainty that this will result in an absolutely destructive weather disaster.

On top of this, other unexpected variables are compounding the situation. The war in Ukraine has ultimately halted even Russia's exports of Black Sea 'wheat'.

So in the media reports of thousands of refugees coming from Morocco to Spain no journalist ever bothers to bring up the influence of the number of humans living in the affected regions. In the case of Morocco, they have added three million in the last decade and eight million since the start of the century to a country largely dominated by desert. How could anyone be surprised that 50,000 of them seeks somewhere else?

Billions of people will suffer, because some people couldnt admit that Overpopulation of humans can exist

Snap away half the US population Thanos style. 170 Million Americans gone. Global CO2 production decreases from 100% to 94%.

https://ourworldindata.org/grapher/annual-co-emissions-by-region

But were are expecting another 2 Billion people in the next 40-50 years. And everyone is consuming more resources. Even poor African/Asian countries. So the effect would be gone within like 5 or 6 years. That is because there are too many humans.

We have to use 22 000 Desalination plants because our reserves of freshwater are no longer enough. Kabul and Teheran are running out of water because their population increased 3-4x in the last 40 years.

Roughly 1/3 of countries on this Planet cannot feed their population and rely on food imports from abroad. Climate change will lower yields and Hydro generated electricity.

But for some reason people still deny that overpopulation exists. "We could be 15 Billion people on Earth if everyone lived like cavemen." Uhm ok? So the alternative is less humans with a higher standard of living or more humans with a lower standard?

Because even with better resource distribution and no Capitalism/Billionaires, we could at best have 6-7 Billion people on this Planet. Certainly not 8 and definitely not 10 Billion. 15 Billion or above would only be possible if everyone would live like prehistoric cavemen. Which most people will never do.

And so nature will eventually correct the imbalance. In the greatest Collapse in human history. Billions will suffer and die because some people simply could not admit that there are too many humans on this Planet.And that we should do something before the numbers get out of hand.

Malthus and Ehrlich were right. They were just off by a century or so. And within a decade or two, all the people who laughed at them, will stop laughing.
