The amount of material to create a self-sustaining colony on Mars would be remarkable. Just thinking about how much infrastructure is required to create a pencil makes my brain hurt. Also you need to consider that Mars has no oil resources. So all of your polymers need to be plant based or created in a bio-reactor. You would need massive pressurized habitats just to grow the food and plant matter to produce your polymers. We can barely do this well on Earth... Honestly, I think it's a great goal to strive for. If we can survive on Mars, maybe we can reach the point we can survive on Earth without destroying it.
