I can argue it's not really that hard. We can even experiment right now to recreate it on Mars, or on Earth with Mars-like conditions (it's certainly much easier to colonize Antarctic than Mars).

Just create big hermetic container, and put there minerals, bacteria and fungi. Heck, people even do it at home with big sealed glass bottles.

No need to bring living biome. Just bring spores, seeds, sperm and eggs.

(As it stands now) It is a multi-generation trip. These humans need to live somewhere and eat something, thus it's logical choice just to ship biome with them. Additional advantage is that error-prone 'boot' process to built up new biome at destination is eliminated.

But this is not the main point. It's still extremely expensive. Imagine that world GDP needs to be taken for few years just to build single ship. Who would agree to that in democratic society?

> These humans need to live somewhere and eat something No, why? Humans will travel in form of frozen sperm and eggs.
