Microplastics and the Fertility Crisis: Joe Rogan Sounds Alarm on Humanity's Survival

Joe Rogan, the 58-year-old podcaster, has issued a stark warning about the future of humanity, likening it to the dystopian 2006 film *Children of Men*, where human reproduction ceases and the world teeters toward extinction. During a recent episode of his show, Rogan sat down with environmental epidemiologist Shanna H Swan to explore the link between toxic chemicals in food and the alarming decline in global fertility rates. The pair argue that microplastics—tiny fragments of plastic pollution—may be playing a critical role in this crisis, threatening not just individual health but the survival of the human race.

Swan, who has studied endocrine-disrupting chemicals for decades, said the modern world's reliance on plastics is poisoning people in ways that are only now becoming apparent. "The big part seems to be that we're being poisoned," Rogan said during the interview. "And we're doing it by virtue of our modern world, where so much of your life relies on plastic." He pointed to the growing presence of microplastics in everything from food packaging to personal care products, which may be seeping into the human body and disrupting hormonal systems critical to reproduction.

The data on declining birth rates is stark. In 1960, the average American household had 3.62 children, but by 2018, that number had plummeted to 1.73, according to Population Education. South Korea's situation is even more dire: its birth rate dropped from 1.20 children per family in 2014 to 0.75 in 2024, as reported by CNN. "They're down quite a bit," Rogan said, referring to the United States' fertility rates. "They're not at the level that we need in order to keep our population." Swan echoed his concerns, stating bluntly, "Fertility is in the toilet."

The pair highlighted how environmental toxins are not only affecting humans but also other species. A study on alligators found that their genitalia have shrunk over decades due to chemical pollution, and their eggs are less viable. Scientist Lou Gillette's research, cited by the National Library of Medicine, revealed that long-term exposure to environmental contaminants has parallels in human health, including reduced fertility and increased risks of cancer and heart disease. "This is not just about humans," Swan said. "It's a warning for the entire ecosystem."

Rogan and Swan also discussed how societal shifts, such as women delaying childbirth to pursue careers, have compounded the problem. "They put their careers aside in their 30s, they decided now it's time to have kids," Rogan said. "They're worried that it's too late." Meanwhile, assisted reproductive technologies like IVF have become increasingly common, but they are not a solution to the underlying causes of declining fertility.

A recent study from NYU Langone Health added urgency to the conversation. It found that nearly 2 million preterm births worldwide are linked to exposure to Di-2-ethylhexylphthalate (DEHP), a chemical used to make plastics flexible and found in cosmetics, detergents, and food packaging. DEHP has also been tied to cancer, heart disease, and infertility. In 2018 alone, 1.97 million preterm births were attributed to chemical exposure, with 74,000 newborn deaths linked to the same toxins. A 2025 study further revealed that preterm babies had significantly higher levels of microplastics in their placentas compared to full-term infants.

Microplastics have been detected in human tissues for years, appearing in breast milk, semen, and even bone marrow. The discovery of microplastics in the placenta in 2020 marked a turning point, raising alarms about the potential for these pollutants to cross the placental barrier and harm developing fetuses. "We're just beginning to understand the full scope of this crisis," Swan said. "It's not just about individual health—it's about the future of our species."

As Rogan and Swan warned, the consequences of inaction could be catastrophic. With birth rates declining globally and environmental toxins accumulating in the body, the world may be hurtling toward a future where human reproduction becomes increasingly difficult—or impossible. "We have to start paying attention," Rogan said. "This isn't just a scientific issue. It's a survival issue.
