Kelly Weinersmith, a biologist and co-author of "A City on Mars," and Zach Weinersmith, a cartoonist, dive into the exciting yet daunting idea of living on Mars. They discuss the necessary resources for survival and the unique challenges of raising children in low gravity. As they explore what daily life might entail—like food production and governance—they also consider the ethical dilemmas of settling a new planet. Ultimately, they highlight why staying on Earth could be a wiser choice for humanity.
Colonizing Mars requires addressing significant health risks like bone loss and muscle atrophy due to its harsh environment.
Ethical concerns about child development and the preservation of Earth highlight the need to solve our terrestrial issues first.

Colonizing Mars: Opportunities and Challenges
Mars is emerging as the primary candidate for human colonization due to its relatively close proximity and critical resources, such as water and carbon, which are essential for supporting life. Research conducted on potential space settlements reveals that successful colonization involves not only sustaining life but also establishing a functioning society where families can thrive. This society would need to maintain careers, raise children, and ensure that future generations can survive and adapt to the Martian environment. However, significant challenges remain, including the need for solutions to life's everyday necessities, governance, and health concerns related to living in a harsh extraterrestrial setting.
Health Risks Associated with Living on Mars
Living in space poses numerous health risks due to the effects of reduced gravity and cosmic radiation exposure, with long-term studies on human endurance outside of Earth's magnetic field still limited. Current data indicates substantial bone loss and muscle atrophy in space, raising concerns about the ability of humans to thrive physically on Mars, especially regarding reproduction and child development. The harsh Martian environment presents unique challenges, such as high radiation levels and the presence of harmful substances in Martian soil, complicating efforts to establish sustainable living conditions. Preparing for these health risks is crucial, as the viability of human life on Mars depends on overcoming these severe physiological effects.
The Ethical Considerations of Mars Colonization
As the idea of colonizing Mars evolves, ethical concerns about the impact on potential future generations arise, particularly regarding health and development in an environment vastly different from Earth. Key questions focus on whether humans, especially children, can develop properly with altered gravity and atmospheric conditions on Mars, and what risks they may face in terms of bone density and exposure to hazardous materials. Additionally, the discussion emphasizes the importance of preserving Earth as a livable environment, questioning the motivations for seeking refuge on another planet. Ultimately, the conversation stresses the need to address and resolve environmental challenges on Earth before venturing into space with aspirations of colonization.
As global warming continues and space technology improves, there is more and more talk about the growing possibility of a sci-fi future in which humans become a multiplanetary species. Specifically, that we could live on Mars. Biologist Kelly Weinersmith and cartoonist Zach Weinersmith have spent the last four years researching what this would look like if we did this anytime soon. In their new book A City On Mars, they get into all sorts of questions: How would we have babies in space? How would we have enough food? They join host Regina G. Barber and explain why it might be best to stay on Earth.
Kelly and Zach Weinersmith's book A City On Mars is out now.
