There is no problem. Only lefties think there is a problem. The planet is not running out of resources. There is heaps of f*** room. Poverty levels (not rates but levels) are falling. Malthusian thinking has been proven as false as Marxs.

Bullshit.
Go dress your male children in dresses you cream pie lefty. You femo men need to start paying attention to science rather then emotion.

If nothing else, the Greta Thunberg spectacle has clearly demonstrated once more that globalists are willing to go any and every length imaginable to advance their agenda. These individuals are so morally rotten that they’re now using an autistic, mentally unstable 16-year-old as a prop to push a hysterical political narrative, which if adopted, would be used as a mechanism to consolidate a level of state power that’s never been seen before.
Huh?
I posted the link to the source of the quoted figures!
You, take a wacko guess without even a quick google search!
It is easy just type in "world population 2100" Even you ought be able to do that?
UN published projected 2100 figure is 11.2 billion. A further increase (although further growth rate decline)
btw No one is suggesting murder or genocide! However there are many on BF who seriously ought consider not breeding!
(as for your later claim - Australia has plenty of "room" and types of "resources", - but not enough water!)

Environmental predictions from ~ 50 years ago:
1. Harvard biologist George Wald estimated that “civilization will end within 15 or 30 years unless immediate action is taken against problems facing mankind.”
2. “We are in an environmental crisis which threatens the survival of this nation, and of the world as a suitable place of human habitation,” wrote Washington University biologist Barry Commoner in the Earth Day issue of the scholarly journal Environment.
3. The day after the first Earth Day (1970), the New York Times editorial page warned, “Man must stop pollution and conserve his resources, not merely to enhance existence but to save the race from intolerable deterioration and possible extinction.”
4. “Population will inevitably and completely outstrip whatever small increases in food supplies we make,” Paul Ehrlich confidently declared in the April 1970 issue of Mademoiselle. “The death rate will increase until at least 100-200 million people per year will be starving to death during the next ten years.”
5. “Most of the people who are going to die in the greatest cataclysm in the history of man have already been born,” wrote Paul Ehrlich in a 1969 essay titled “Eco-Catastrophe! “By…[1975] some experts feel that food shortages will have escalated the present level of world hunger and starvation into famines of unbelievable proportions. Other experts, more optimistic, think the ultimate food-population collision will not occur until the decade of the 1980s.”
6. Ehrlich sketched out his most alarmist scenario for the 1970 Earth Day issue of The Progressive, assuring readers that between 1980 and 1989, some 4 billion people, including 65 million Americans, would perish in the “Great Die-Off.”
7. “It is already too late to avoid mass starvation,” declared Denis Hayes, the chief organizer for Earth Day, in the Spring 1970 issue of The Living Wilderness.
8. Peter Gunter, a North Texas State University professor, wrote in 1970, “Demographers agree almost unanimously on the following grim timetable: by 1975 widespread famines will begin in India; these will spread by 1990 to include all of India, Pakistan, China and the Near East, Africa. By the year 2000, or conceivably sooner, South and Central America will exist under famine conditions….By the year 2000, thirty years from now, the entire world, with the exception of Western Europe, North America, and Australia, will be in famine.”
9. In January 1970, Life reported, “Scientists have solid experimental and theoretical evidence to support…the following predictions: In a decade, urban dwellers will have to wear gas masks to survive air pollution…by 1985 air pollution will have reduced the amount of sunlight reaching earth by one half….”
10. Ecologist Kenneth Watt told Time that, “At the present rate of nitrogen buildup, it’s only a matter of time before light will be filtered out of the atmosphere and none of our land will be usable.”
11. Barry Commoner predicted that decaying organic pollutants would use up all of the oxygen in America’s rivers, causing freshwater fish to suffocate.
12. Paul Ehrlich chimed in, predicting in 1970 that “air pollution…is certainly going to take hundreds of thousands of lives in the next few years alone.” Ehrlich sketched a scenario in which 200,000 Americans would die in 1973 during “smog disasters” in New York and Los Angeles.
13. Paul Ehrlich warned in the May 1970 issue of Audubon that DDT and other chlorinated hydrocarbons “may have substantially reduced the life expectancy of people born since 1945.” Ehrlich warned that Americans born since 1946…now had a life expectancy of only 49 years, and he predicted that if current patterns continued this expectancy would reach 42 years by 1980, when it might level out. (Note: According to the most recent CDC report, life expectancy in the US is 78.8 years).
14. Ecologist Kenneth Watt declared, “By the year 2000, if present trends continue, we will be using up crude oil at such a rate…that there won’t be any more crude oil. You’ll drive up to the pump and say, `Fill ‘er up, buddy,’ and he’ll say, `I am very sorry, there isn’t any.'”
15. Harrison Brown, a scientist at the National Academy of Sciences, published a chart in Scientific American that looked at metal reserves and estimated the humanity would totally run out of copper shortly after 2000. Lead, zinc, tin, gold, and silver would be gone before 1990.
16. Sen. Gaylord Nelson wrote in Look that, “Dr. S. Dillon Ripley, secretary of the Smithsonian Institute, believes that in 25 years, somewhere between 75 and 80 percent of all the species of living animals will be extinct.”
17. In 1975, Paul Ehrlich predicted that “since more than nine-tenths of the original tropical rainforests will be removed in most areas within the next 30 years or so, it is expected that half of the organisms in these areas will vanish with it.”
18. Kenneth Watt warned about a pending Ice Age in a speech. “The world has been chilling sharply for about twenty years,” he declared. “If present trends continue, the world will be about four degrees colder for the global mean temperature in 1990, but eleven degrees colder in the year 2000. This is about twice what it would take to put us into an ice age.”

This is what happens when adults exploit children like Greta to push their agendas. Making kids feel like they have no future will lead to things like this happening. Disgusting.

New approach suggests path to emissions-free cement
by David L. Chandler, Massachusetts Institute of Technology
September 17, 2019
The findings are being reported today in the journal PNAS in a paper by Yet-Ming Chiang, the Kyocera Professor of Materials Science and Engineering at MIT, with postdoc Leah Ellis, graduate student Andres Badel, and others.
"About 1 kilogram of carbon dioxide is released for every kilogram of cement made today," Chiang says. That adds up to 3 to 4 gigatons (billions of tons) of cement, and of carbon dioxide emissions, produced annually today, and that amount is projected to grow. The number of buildings worldwide is expected to double by 2060, which is equivalent to "building one new New York City every 30 days," he says. And the commodity is now very cheap to produce: It costs only about 13 cents per kilogram, which he says makes it cheaper than bottled water.
So it's a real challenge to find ways of reducing the material's carbon emissions without making it too expensive. Chiang and his team have spent the last year searching for alternative approaches, and hit on the idea of using an electrochemical process to replace the current fossil-fuel-dependent system. Ordinary Portland cement, the most widely used standard variety, is made by grinding up limestone and then cooking it with sand and clay at high heat, which is produced by burning coal. The process produces carbon dioxide in two different ways: from the burning of the coal, and from gases released from the limestone during the heating. Each of these produces roughly equal contributions to the total emissions. The new process would eliminate or drastically reduce both sources, Chiang says. Though they have demonstrated the basic electrochemical process in the lab, the process will require more work to scale up to industrial scale.
First of all, the new approach could eliminate the use of fossil fuels for the heating process, substituting electricity generated from clean, renewable sources. "In many geographies renewable electricity is the lowest-cost electricity we have today, and its cost is still dropping," Chiang says. In addition, the new process produces the same cement product. The team realized that trying to gain acceptance for a new type of cement—something that many research groups have pursued in different ways—would be an uphill battle, considering how widely used the material is around the world and how reluctant builders can be to try new, relatively untested materials...............
The new process centers on the use of an electrolyzer, something that many people have encountered as part of high school chemistry classes, where a battery is hooked up to two electrodes in a glass of water, producing bubbles of oxygen from one electrode and bubbles of hydrogen from the other as the electricity splits the water molecules into their constituent atoms. Importantly, the electrolyzer's oxygen-evolving electrode produces acid, while the hydrogen-evolving electrode produces a base. In the new process, the pulverized limestone is dissolved in the acid at one electrode and high-purity carbon dioxide is released, while calcium hydroxide, generally known as lime, precipitates out as a solid at the other. The calcium hydroxide can then be processed in another step to produce the cement, which is mostly calcium silicate.
The carbon dioxide, in the form of a pure, concentrated stream, can then be easily sequestered, harnessed to produce value-added products such as a liquid fuel to replace gasoline, or used for applications such as oil recovery or even in carbonated beverages and dry ice. The result is that no carbon dioxide is released to the environment from the entire process, Chiang says. By contrast, the carbon dioxide emitted from conventional cement plants is highly contaminated with nitrogen oxides, sulfur oxides, carbon monoxide and other material that make it impractical to "scrub" to make the carbon dioxide usable. Calculations show that the hydrogen and oxygen also emitted in the process could be recombined, for example in a fuel cell, or burned to produce enough energy to fuel the whole rest of the process, Ellis says, producing nothing but water vapor.
In their laboratory demonstration, the team carried out the key electrochemical steps required, producing lime from the calcium carbonate, but on a small scale. The process looks a bit like shaking a snow-globe, as it produces a flurry of suspended white particles inside the glass container as the lime precipitates out of the solution. While the technology is simple and could, in principle, be easily scaled up, a typical cement plant today produces about 700,000 tons of the material per year. "How do you penetrate an industry like that and get a foot in the door?" asks Ellis, the paper's lead author. One approach, she says, is to try to replace just one part of the process at a time, rather than the whole system at once, and "in a stepwise fashion" gradually add other parts.

New approach suggests path to emissions-free cement
It's well known that the production of cement—the world's leading construction material—is a major source of greenhouse gas emissions, accounting for about 8 percent of all such releases. If cement production were a country, it would be the world's third-largest emitter.

An Angry Middle-Aged Man's Guide to Greta Thunberg – The Chaser
Are you angry at Greta Thunberg? Do you find yourself enraged that a 16 year old girl would have the temerity to ask adults to listen to the science? This guide is for you.

I am mistaken. They no longer have population peaking around 2070 like in previous projections. But they do have it basically coming close to plateauing. The fears of exponential global population growth are over. And there is one major reason for it. condoms. They have changed the course of human history.

Thunberg is like soooooo 1992
From Wikipedia.
"Her father, geneticist and environmental activist David Suzuki, is a third-generation Japanese Canadian.While attending Lord Tennyson Elementary School in French Immersion, at age 9, she founded the Environmental Children's Organization (ECO), a group of children dedicated to learning and teaching other youngsters about environmental issues.in 1992, at age 12, Cullis-Suzuki raised money with members of ECO to attend the Earth Summit in Rio de Janeiro. Along with group members Michelle Quigg, Vanessa Suttie, and Morgan Geisler, Cullis-Suzuki presented environmental issues from a youth perspective at the summit, where she was applauded for a speech to the delegates. The video has since become a viral hit, popularly known as "The Girl Who Silenced the World for 5 Minutes".[

Ofcourse not. But i have no doubt with sufficient economic development the world could easily deal with a trillion people.
Australia could probably handle a billion. I mean if humankind is on the brink of colonizing mars then surely we can colonize the australian inland.
Exactly. Once we have extremely cheap renewable energy then we can grow crops in 10 story buildings using artificial light. All this agriculture land will suddenly become redundant. I expect this to happen within the next 50 years. Possibly 25. It will be like the earth has doubled or tripled in size.
