>how are we supposed to build a second home on a dead, ruthlessly hostile planet until we demonstrate ourselves capable of stabilizing the biosphere and building a sustainable long-term civilization here because its unique challenges and constraints may make us develop technology that we wouldn't otherwise that may in turn out to be useful back on earth. Much of our technological advancements come from military research, where there was no civilian demand. We developed computers so we could break encryption, we developed the internet as a successor to arpanet a military network originally made to maintain command and control in event of nuclear exchange. standardized clothes sizing was invented to make uniforms more cheaply. satellites were invented so we could spy on our military rivals. the entire space program was a spin off of ICBM program. Nuclear power came from atomic bomb research, we have developed many advaced prosthetic due to injured veterans needing them. weather prodiction thanks to radar to detect enemy planes. But what if we could have something less self destructive than war that would germinate new technologies? Thats what a reasons to colonizes space. space colonization gives us many of the same challenges war does without the need for mass loss of life. Needs for new materials, new means of generating power, new modes of transportation. space exploration will give us new frontiers to strive against rather than find better ways to murder each-other. the ease of earth doesn't provide those challenges. I can dig up my back yard throw seed on the ground and will have vegetables to eat in the fall but i have learned nothing, find a way to grow food from lunar or martian regolith and you just have invented a way to rapidly create new soil and solved earths soil erosion problems ans well as found new ways of removing toxins from contaminated environments.

We already have no till agriculture. The plants terraform the soil for us. The problem with this terraformation is that you need to rotate the plants because every plant terraforms the soil in a different way. Plants don't deplete the soil unless you replant the same plant over and over again and destroy terraforming progress through tillage and harvest it and then never bring the poop back. Some people will now say that avoiding soil depletion in the short term is a bad idea because it means using a little bit more land (or bring up incorrect numbers).
