While I think the idea of colonizing Mars is a fantasy, I also disagree that your problems are “easy”.
Because all those problems are human problems. Humans are short-sighted and selfish. Climate change stands out here. Sure, we know to fix that. Now make it happen. Get politicians to tell the fossil fuel extractors and refiners in their districts are out of a job. Now get people to give up their cars. Now tell people they can’t eat meat.
Oh, those are extreme examples, you might say. There are economic incentives and taxation that could ease the transition and provide incentives. We can develop better photovoltaics and a host of other green energy tech. Sure, we absolutely can! Now create those taxes so they don’t create perverse incentives, and we can have reduced tax spec…ah, and now it is way way way beyond easy.
