If you care to continue in this world with families lasting it cannot be realistically with civilization. Sustainable ways independent from civilization are needed for that. So join together for using some land away from cities, and from farmers and ranchers, where everything can be managed independently with the small community you can be, with the things needed growing there, with good land and water there for it and the right amount of sun. This would not involve moving further up to be nearer arctic places. Disasters to our society in this world will so likely come soon.
