This worldwide zone is easily the most comfortable for long-term survival. However, with such attractive land will come a host of problems. The wilds of Northern Canada are sure to be crowded with refugees. Caught unprepared, these panicked mobs will surely flee north. For at least the first year, they will roam the wilderness, stripping the land of food, turning to violence to obtain equipment, perhaps even turning to cannibalism in the cold winter months. Brigands will no doubt be among them or will follow in the later years when some decide to attempt a safe settlement. And of course, there is always the zombie threat. Temperate forests are still relatively close to civilization, as well as being dotted with outposts of humanity. Ghoul encounters would be ten times as likely as under normal circumstances. With an influx of refugees, the chances of the undead simply following them north is almost a given. Remember also, the problem of zombies freezing in the winter and thawing in the summer. Choose an area only if it is isolated by natural boundaries: mountains, rivers, and so on. Anything less-even if it seems far from humanity-will be too much of a risk. Do not believe that the vast expanse of Siberia will be any safer than Northern Canada. Remember, to the south of this thinly peopled wilderness are both India and China, the two most populous nations on Earth.
Refugees will not consider these seemingly barren lands capable of supporting life. Those who try will perish without large stores of supplies, elaborate equipment, or extensive knowledge of the environment. Bandits will also be hard-pressed to survive. In all probability, none will venture this far north. The living dead may reach your camp, however. Those that have migrated north following fleeing refugees, or former refugees now reanimated as zombies, may detect your presence and signal others. Their numbers will not be great and can be handled by those in your group. All the same, build your defenses strong and keep constant vigilance. As with temperate forests, be prepared for zombie activity to follow the seasons.
This environment is, without a doubt, the harshest on the planet. Extremely low temperatures with a high wind chill can kill an exposed human in seconds. Building materials will consist mainly of ice and snow. Fuel will be scarce. Medicinal or any other type of plants are unheard of. Food is plentiful but takes skill and experience to obtain. Even in summer, hypothermia will be a constant danger. Every day will be spent on the fringe of existence. One mistake regarding food, clothing, shelter, even hygiene could mean certain death. Many people have heard of Allariallak, the Inuit whose life in the frozen Hudson Bay region was documented in the film Nanook of the North. Few know that “Nanook” starved to death a year after that documentary was shot. This is not to say that life in the polar regions is an impossibility. People have been doing it successfully for thousands of years. What it will take is ten times the knowledge and determination to even attempt a life at the top or bottom of the world. If you are not ready to spend at least one winter practicing under these conditions, do not try it when the time to flee comes. So why go? Why risk death from such a hostile environment when the goal is to stay alive? The truth is that the environment should be your only worry. Refugees and bandits will never make it that far. The chance of zombies randomly wandering that far north are one in 35 million (a proven calculated statistic). As with temperate forests and tundra, you do run the risk of an odd ghoul freezing and thawing in its travels. If you are camped near a coastline, watch for one possibly brought ashore by the current or a derelict-infested ship. Coastlines also leave you vulnerable, in the beginning, to pirates. (More on this concerning islands.) Maintain some means of static defense and always keep alert, although the need for both is relatively less than for any other environment.
