What If We Moved All 8 Billion People To Mars?

What If | August 16, 2026



War, environmental destruction, global warming, species extinction… Spaceship Earth is being trashed by its crew. It’s looking like humanity needs a Plan B. Fast. And, the obvious candidate? It’s staring down at us every night. Mars.

It has a total surface area almost equal to Earth’s entire land area. So there’s room for all of us.
And, unbelievably large sums of money are being directed to space exploration… So it’s not so out there to ask, What if we moved all 8 billion of us humans to Mars?

    Tech companies spend billions trying to populate a dead planet, but don't seem to care about spending the same amount to save our current planet that has sustained life for thousands of years.

    22:43 No, humans have not caused 60% of all animal species to go extinct. The "60%" figure comes from a frequent misinterpretation of a major WWF Living Planet Report, which stated that human activity led to an average 60% decline in the population sizes of monitored vertebrate species (mammals, birds, fish, reptiles, and amphibians) between 1970 and 2014 (later updated to nearly 69%). It means individual animal numbers shrank drastically, not that 60% of species vanished

    Dang finding that this meme is so relatable to this channel is perfection. These videos are actually Gold.
