Elon Musk has been commenting for some years now on the threat of population decline, not expansion as the environmentalists are obsessed with. As he pointed out in a recent tweet, declining fertility combined with an ageing population, in places like Japan is going to lead societies ceasing to function, as Japan’s prime minister recently warned. In the US, despite runaway immigration from illegals, mainly men, the Social Security system's Central Trust Fund's reserves will be depleted in 2033, due to the ageing population, and immigrants are not immortal, and age as well. US births have dropped an average of 2 percent a year since 2014, and show no indication of coming out of the nose dive. “Population collapse is a major risk to the future of civilization,” Musk has said.
He is correct, but matters are even worse, with the decline human sperm quality and quantity; over the past 50 years sperm counts have declined by more than 50 percent across the planet, and if the trend continues, thought to be caused by hormone-altering chemicals that are everywhere, then according to one prediction, humanity will face extinction, or at least, a reproduction crisis:

“Elon Musk, who has been encouraging the public to have more babies, is back with concerns about a population collapse amid a falling birth rate.
In a tweet on Friday, Musk said that the U.S. would face consequences as a result of a declining birth rate and that "Japan is a leading indicator."
The billionaire entrepreneur was responding to a tweet about a report regarding the projected depletion of Social Security funds by 2033.
Reuters reported that the country's Social Security system's central trust fund's reserves will be depleted in 2033 — one year earlier than estimated — while finances surrounding the nation's Medicare program have improved slightly.
According to data from the U.S. Centers for Disease Control and Prevention's National Center for Health Statistics, approximately 3.7 million babies were born in the U.S. in 2021, about 46,000 more than were born in 2020, but the 1% increase still put the number short of 2019 levels.
Births have also dropped by an average of 2% yearly since 2014, including a decline of twice that much between 2019 and 2020.
Last month, Japan's prime minister said that the country was on the brink of being unable to function amid a steep fall in the country's birth rate. In 2021, Japan's population registered at 125.5 million, according to CNN.
In a tweet shared in January, Musk reiterated his warning of a population collapse, saying, "Population collapse is a major risk to the future of civilization." He also shared a link to World Bank data, which showed that the world's fertility rate was at its lowest since the 1960s.
Last August, Musk warned that "population collapse due to low birth rates is a much bigger risk to civilization than global warming."
In a podcast, he also said that "people are living longer —that's the only reason why the population of Earth isn't plummeting."”
