As I drove my car from my city of residence to Holon, the city of Olamot 2006, and as I was thinking about Israeli space stations, I came upon the following question.
What modifications are needed on and in Earth in order for it to house 100 billion (1011) humans, without serious interference with other life forms?
A full answer needs to consider the following:
- Fresh water
- Natural preserves
- Public health
- Manufactured goods (such as clothes and entertainment)
- Enough space per capita to prevent feelings of claustrophobia
