Putting people on Mars US equally useless. Any colony on Mars would require enormous support from Earth. It would never be self-suffient. Mars would need water, air, energy, raw materials, fuel and everything else for (basically) ever. There is zero to be gained (here) from a Mars colony. Mars lacks a magnetic field, air to breath, water to drink or cultivate crops, a temperature suitable for plant or animal life, fuel sources to build industry, supply chains for the construction or maintainence of the simplest electrical systems. Talk of Mars is purely a PR play. Someone will be first. Yay. But Mars will play no part in Earth's future.
