Advertisements With the opening of the ring, Mars has basically abandoned the terraforming project. Why try to transform a world that could take a hundred years or more to accomplish when there are thousands of habitable new worlds on the other side of the ring? People currently living on Mars will never see the project completed in their lifetime so why wait for something that will never happen for them when they can just colonize new worlds? I just finished reading Nemesis Games so I don't want to spoil the last couple of episodes. I don't recall if it was something I read in the book or if it was revealed in one of the episodes that already aired, but I believe there is speculation that there is someone higher up that is controlling Marco and the belters. Unless Earth can recover from the asteroid strikes and vegetation can start thriving again, the Earth is a dying planet. Without vegetation, there is no more oxygen production and the atmosphere will slowly become poisoned with too much carbon dioxide unless they can build CO2 scrubbers on a massive scale like the ones they use onboard the spaceships.
