Tesla ($TSLA@US) CEO Elon Musk has again warned the world should be worried about a population collapse. In a series of tweets, Musk dwelt on the rapidly declining birth rates around the world and its impending threat to human civilization. “If there aren’t enough people for Earth, then there definitely won’t be enough for Mars,” Musk noted, with a frowning face emoji. The tech billionaire also termed the projections about overpopulation by the United Nations as “utter nonsense,” and attached the links for some articles that talked about the projected fall in the global fertility rate. Musk’s comments come amid reports of a growing number of people around the world deciding not to have children due to concerns such as climate change, inequality, and financial worries. Musk has said earlier that the shrinking population is a threat to human civilization. Musk dreamed of colonizing Mars and founded his space company SpaceX with the mission to make humanity multi-planetary. He recently said SpaceX will land humans on Mars in five to 10 years. Tesla shares closed 1.8% lower in yesterday’s regular trading session at just over $1,000.00.
