The planet doesn't need a population cull, that far-left shite has been spouted for years by mentally ill sycophants and debunked that many times.

A belief in overpopulation is factually incorrect. Humans are not cockroaches or bacteria. We do not reproduce exponentially until the food runs out. Instead, as a nation becomes richer and more developed, people naturally have fewer children, choosing to invest more of their time and resources into raising one or two children instead of ten. That's been the pattern in every rich country around the world, including the United States.
Despite this, global population models often projected that humanity would continue growing well into the 22nd Century before peaking at around 11 or 12 billion people and then declining. But some demographers are starting to question this. Last year, Darrell Bricker and John Ibbitson wrote a book called Empty Planet that claimed that the human population would peak and decline this century, beginning in roughly 30 years. Now, a new study confirms this view.
Published in The Lancet, a study from the University of Washington's Institute for Health Metrics and Evaluation projects that the world population, which now stands at 7.8 billion, will peak in 2064 at 9.7 billion (95% CI: 8.8 billion to 10.9 billion) then fall by 2100 to 8.8 billion (95% CI: 6.8 billion to 11.8 billion). If the UN's Sustainable Development Goals are met, which include education and access to contraception, the authors project a population of 6.3 billion (95% CI: 4.8 billion to 8.7 billion) by 2100, smaller than it is today.
