Colonize earth (split from Generational craft (split from Terraforming the Solar System))

[Airbrush]

Rather than colonizing Mars, the Moon, asteroids, or a giant solar-system cruiser, we should colonize Earth!  We could build bunkers that resist the worst natural disasters.  People living near the ocean should be prepared with a tsunami and hurricane shelter.

Establish self-sufficient settlements in areas previously uninhabited, such as deserts that are near the ocean, Northern Canada, or Antarctica.  Such independent settlements would use solar and wind power, and enough renewable biofuels (those in warm climates) to satisfy energy required for a growing settlement, and pump sea water inland to desalinate.  Such settlements could produce food on farms and use surplus fresh water to plant trees where trees and other vegetation had not grown before.

Sooner or later governments will place restrictions on population.  Like China's one child per couple policy, but maybe not that strict.  Maybe a 2-child limit.  Maybe medicine would progress to the point that people could know in advance it they should have children.   Maybe they learn their children would have genetic problems, so they decide to not have children.

There is no needfor  restriction on population. The models show Earth's population to reach the top on 11 billion inhabitants in around 2100 . see UN model  https://population.un.org/wpp/Download/Probabilistic/Population/

Could you please explain this model?  How does this tell you that 11 billion is the max?  What about fresh water shortages?  How about wars over resources?  I always thought that unless people intentionally restrict population growth, there would be a big, accidental war that eliminates half the population in the aftermath of a nuclear exchange.  Oops! 😲

If somebody wants to be immortal, cannot have, or rather should not have, child.. You have to choose.. Only mortals can have children.

If you're immortal, children will want to be immortal too (and you will want them to be with you forever (I hope so!) ), and their grandchildren too etc. etc. and it will go on..

It's function f(x) going to infinity. Which will take the all resources, the all matter, and the all energy from the Universe.

 

Netflix even made movie showing such hypothetical future society which has immortal people class.

Altered Carbon

https://www.imdb.com/title/tt2261227/

In the movie, people cannot die because the all data from their brains are recorded all the time, and stored in the cloud (servers), once per day, or more often.

So, if somebody kills somebody, or they have accident etc., clone of a person, with restored data from his/her brain, is recreated.

They want to have the all power they have forever.. and their children (even though they are mature! and living hundreds years) are treated like children.. Which causes their frustration, because they are not appropriately treated.. etc. etc. and many other similar issues (unknown to the modern humans).

*) replace "immortal" by "living hundreds/thousands/millions/as long as they want to/ of years", if you need to..

 

Today people are living 3x times as long as in medieval and ancient times.

Now imagine situation in which people are living 3x times as long as now. And are healthy, powerful etc. because of nano-robots fixing them all the time or so..

 

ps. Move on, to the cosmic space, right now..

I can't remember exactly. This info comes from a book from physician Hans Rosling founder of the Gapminder Foundation. It is a very interesting read, google for gapminder & take time there, it may change your world view.

 

In short, following worldwide data (not speculations), the world is maybe bad, but it is getting better, not worse.

 

Title of the book: Factfulness. Small book cheap. But plenty of info free from gapminder.

The world HAS been getting better, until population growth, climate change, and water and other resource shortages intersect...soon.
