@agr18181 - “grow iron on Mars” While the statement may be not technically correct, the ability to grow plants which could mine iron on mars may be possible, if there is enough iron in the soil. The soil would likely have to go through a tumbler, to remove the sharp edges, so plant roots can grow better… plus get an oxygen dome and keep water from vaporizing & blowing off the planet.

Mines are huge, they could generate a consistent amount of raw resources a year, and a business plan can be made. If it is unprofitable, a tax rebate can be done to make it happen It all depends on the desire to clean up the environment

Hi @-opus - “Unfortunately China, India, and the U.S. are still increasing” Not really. Population growth rates 2021: China- 0.1% annually India- 0.8% annually U.S.- 0.1% annually In the US (and probably China), any population growth is driven by immigration… so really, those places are in decline.

@rp9674 - “keep making more people” The West is in population decline, which is why they are dependent upon immigration. The culture in The West is so screwed up, political forces are allowing people to immigrate illegally, to make up for the shortfall of people. Nope, Westerners are so suicidal, Western civilization would disappear in no time at all, they are producing hardly any people at all.

@agr18181 - “small details” They have been working through those details for over a decade. Devon Island in Canada has similar conditions. A small nuclear reactor can provide necessary energy, for a long period of time.

Hey @agr18181 - water may be at the poles, a robot may have to do a run & harvest some, using autonomous programming. 40 years ago, I programmed a BigTrak to go around my house and drop off stuff at a destination… systems are much more intelligent today! 3D Printers may produce various building materials required for a dome. Living quarters would need to be underground to some extent, because it is so cold, robots could dig those… that material could then be processed to create the material to print the building materials with… I have seen 3D printed domes made in the US - quite interesting! Really, the transparent portions of the done will need to be transported… unless they could make glass up there. If not, just transfer sand, or pick up the sand on the moon before sending it to Mars. Anything is possible with some robots, 3D printing parts, and enough energy. We have what we need today. The problem of getting off Mars, after arriving, is a bigger problem. SpaceX is closer to anything we have ever seen, with rocket boosters that can land vertically. Nuclear engines can be used to handle the propulsion between the planets. The need for solid or liquid fuel to get out of the atmosphere & gravitational fields is still a problem. Take people out there, excrement will be available as organic material for soil conditioning. Plenty of people don’t want to have children on the earth, they are perfect candidates for living on Mars, since they are not concerned about any next generation, so they would live well there. In some ways, it would be like early settlers leaving Europe and headed to the New World. Most died at first, but some flourished.

@rp9674 - “decline in population growth” When populations are not replacing themselves, that is the time to be concerned. Longevity of people obscures the catastrophe to come (using population growth as a sole metric) for another half century… longevity obscures recovery for another half century. By the time the population is in decline, it may already be too late to recover civilization… because there are not enough fertile people to sustain civilization, care for elderly, and may not be able to birth enough children to turn around the situation (at a minimum, for about a quarter century.) Average live births per woman is a better metric to watch. Needs to be slightly higher than 2 in order to sustain civilization. Needs to be slightly higher in case of disease, genetic defects, war, accidents, mental illness (suicide, gender dysphoria, sexual stimulation/preference, etc.) For every woman not having children, some other woman needs to properly raise 4+. This is a huge burden to place upon fertile women for the sake of human survival & civilization… this is a huge burden to place upon responsible men, who father those children. It is pretty selfish of people to put such a burden on others, when they are fertile, intelligent, and earning any kind of pay check.

@rp9674 - “risk famine and drought” That is our own dumb problem… it is called build dams to replenish the aquifers & control flooding, and grow enough food. Idiots in California tax to build dams that they never build, then complain about drought. Idiots in the Federal Government allow California to suck water through the Rocky Mountains, reducing the water feeding the East Side of the Rockies & diminishing water going to the Colorado River… and complain that Lake Mede is at record lows & complain aquifers are diminishing East of the Rockies. Idiots in the US are now destroying dams, in cooperation with the Federal Government. The insanity is beyond description. These are not population problems, they are human causes issues.

@rp9674 - “misguided people who think we can engineer our way out of every problem” Honestly, if they just did what they said they would do, like build the dams they taxed people to build, California would not have a water problem. “fix climate change” Draining water from the East side of the Rockies, that gets less rain than the West Side of the Rockies, is creating climate crisis. “never consider population growth” Even with unrestricted migration to California, population is in decline. 2022 - 39.14 million 2021 - 39.03 million Complete mismanagement

@notone4540 - “there is no iron on Mars” - Mars is literally filled with iron. “big business would create GMO plants” and before that, individuals would cross & cull plants to produce desirable characteristics & remove undesirable characteristics through intelligent selection for thousands of years... plant breeding is done today. There is nothing keeping you from doing it & sharing the results with others. If you don’t want to do it, then you pay 💰 someone else to do it. A worker is with their wages, Slavery is a thing of the past.

@notone4540 - “create my own plant varieties” - terrific!!! “gmo’s would be pushed for this whole mining idea” - who cares? Let’s clean 🧼 it up! “never went to the moon” - The photos from Lunar Reconaissance Orbiter (LRO) show the flags are still casting shadows - except the one planted during the Apollo 11 mission.

@notone4540 - “never went to the moon… no flag on the moon, no LRO” Mirrors 🪞 were left on the lunar surface, by multiple manned lunar missions, and generations of scientists have been firing lasers at the moon 🌙 to measure the distance from the earth. Anyone can use the mirrors, not just NASA or government… since the mirrors are available for anyone to use. The McDonald Observatory, run by the University of Texas at Austin, used the mirrors & firing lasers over time, to discover that the moon is moving away from Earth at a rate of two-and-a-half inches a year. Those mirrors 🪞 exist, were out there by someone, and third-party non-government people have been using them for decades. France sent a reflector to the moon 🌙, via an unmanned Soviet mission on November 17 in 1970. Soviet lander & rover stopped reporting in on September 14 in 1971. Circa February 2010, high-resolution camera on NASA's Lunar Reconnaissance Orbiter (LRO) obtained images of the landing site. On April 22 in 2010, laser pulses were sent from the 3.5 meter telescope at the Apache Point Observatory in New Mexico. They re-discovered the lost Lunokhod 1 reflector, pinpointed its distance from Earth, and triangulated the reflector's latitude and longitude on the moon. It is hard to believe that the French, Russians, and American government could keep a secret about all of their manned & unmanned moon 🌙 visits are fake… with generations of scientists & college students faking it all.
