Do you think humans will ever colonize Mars? What would life there actually look like?

The short answer is yes, I think humans will probably establish some form of permanent presence on Mars eventually. Whether that deserves the grand title of “colonization” is another matter entirely.

Human beings have always been explorers. We crossed oceans, climbed mountains, and sailed into places that previous generations thought unreachable. Mars feels like the next chapter in that story. The technology is advancing, the ambition certainly exists, and there are powerful voices arguing that becoming a multi-planet species is essential for humanity’s long-term survival.

But before we get carried away with visions of thriving Martian cities beneath glass domes, it is worth asking a more uncomfortable question:

Why are we so eager to leave a planet we are still struggling to look after?

Earth is not merely our point of origin. It is, so far as we know, the only place in the universe where forests breathe, oceans teem with life, and countless species coexist in an astonishingly complex web. Yet we continue to pollute rivers, destroy habitats, overconsume resources, and alter the climate at a pace that many ecosystems struggle to adapt to.

There is something slightly ironic about dreaming of transforming an entire planet when we have not yet learned how to live sustainably on the one that already supports us.

Mars is often portrayed as a backup plan. In reality, it would be a brutally hostile world. The atmosphere is far too thin to breathe. Radiation levels are dangerous. Temperatures can plunge to extremes that make Antarctica seem welcoming. Even the dust may pose serious health risks. Any early settlers would live inside sealed habitats, dependent on technology for air, water, food, and survival itself.

Life there would probably look less like a science-fiction adventure and more like a permanent research station. Imagine a cross between a submarine, an Antarctic base, and a greenhouse. Every litre of water would be recycled. Every kilogram of food would matter. Every piece of equipment would need maintenance. The simple act of stepping outside would require a spacesuit.

In many ways, Mars would remind us just how extraordinary Earth really is.

Perhaps that is the greatest value of exploring Mars. Not as an escape route, but as a mirror. A stark, red reminder of what a living planet is worth.

I am not opposed to Mars exploration. Scientific discovery has always expanded human understanding, and there is much we can learn from venturing beyond our world. But I am wary of the narrative that suggests we can neglect one planet because another might someday be available.

A species that cannot live responsibly on Earth is unlikely to suddenly become wise and sustainable on Mars.

So yes, I think humans may eventually build settlements there. They may mine ice, grow food under artificial lights, and establish small communities beneath protective shelters. But if we ever reach that point, I hope we do so having first learned the lessons that Earth has been trying to teach us all along.

The future of humanity may indeed include Mars.

But our responsibility begins here.

Stay safe
