Earth is lost ... but we don't want to, we want to be resiliant and I think we can be
whit the wars on earth (and the Titans) I suppose that the climat had extremely changed and Terraforming work had to be done (not forgetting reconstruction efforts) I suppose basically the same things await on mars and Venus so how would you reclaimed earth (will you ?) or you prefer starting new on a other planet (extra-solar, thanks to the gates) ? in the core book they said that asteroïds minors ship some iceroïds to mars but after you have a breathable atmosphere you will have to fertilize sol, plant some genetically modified crop but Mars is no earth will it keep it's atmosphere and if not how will you keep it ? so how we tranforme the solar system to be a more livable place ?
