The population is not increasing. There is an increase in life span. people are living longer Musk said that the population on earth hasn't plummeted but it will.

The UN expected the world's population to increase from 7.7 billion to 9.7 billion by the year 2050.

The ratio of adult diapers to baby diapers is one thing to keep an eye on. The country has more adult and baby diapers. Adult diaper sales have outpaced those for babies in Japan.

He said there wouldn't be enough people to move to Mars if the demographic crisis continued.

It's like anticlimactic that Musk says civilization will die with a whimper. I would rather civilization ended with a bang than with a whimper.
