Answer 1

elon musk answer: because the capitalist world economy requires constant, even exponential, growth and we can’t keep extracting and investing and growing with finite total resources and a steady world population. And he really wants to believe in infinite growth

real answer: because climate change is going to significantly change our ecosystem, impacting food growth both directly and indirectly, in the coming decades and we don’t know how well we’ll manage that yet. If we can stop crops from failing worldwide, and become comfortable with way less consumption in 1st world countries, we can absolutely live with falling birth rates.
