The Earth might be destroyed, but lets face it: It won't be destroyed for hundreds of years. When that day does come, how will we move? Who will provide the money for 7 billion spacesuits and millions of rockets to Mars? Even if we provide all the money in the world, it will be impossible for humans to live on due to the low gravity.
Yes, but mars is to small for the entire earth, They would only take people who would help Mars thrive in their quest to colonize, And the Gravity problem will be solved because NASA is working on a project to build a space station on mars, Along with building a machine to control Gravity.
I'd like to thank my opponent for making this debate possible. Anyway, So we just let the other 3 billion people or so die? That's very inhumane. Also, who's going to fund the mission? The U.S.? They're 17 trillion dollars in debt, and going to be much more for sending ONE man to Mars. And even though the gravity problem will be solved, we humans would destroy planet Mars like we're destroying planet Earth.
Even though the earth destroys itself, we are helping it destroy itself by polluting, global warming, and creating (in part) more greenhouse gases. Anyway, back on track. You'd need millions of space stations, each one costing millions of dollars. There would be too much money spent and you also need many millions of space rockets, costing more debt for every country. Also, who will pay all of the cost? Even if everyone pools in all of their money, we still won't have enough. Moving to Mars is pretty much useless, but could be possible for a few hundred or thousand people.
I know this debate is pretty useless, because science proves that the human race will be extinct before Earth destroys itself, but there's a lot of "what ifs" in the process, but I enjoyed this as my first debate, and thanks for creating this debate, SacredBread. Best of luck to you, too.
