Wood- The reason why we would need water in a Zombie outbreak is because for a human to survive in the wild they need to have a shelter. So if we have wood we can built a shelter to live in which there are a lot of forests in North Carolina.

Plants- The reason why we would need plants in a Zombie outbreak is because for a human to survive they need to eat because if they go three weeks without eating they could die but since plants give food, we could eat that because there are a lot of edible plants in North Carolina.

Animals- The reason why we would need animals in a Zombie Outbreak is because humans can't just eat plants to survive because humans have to have protein. So we can hunt the animals for meat/protein and there are lots of animals in North Carolina.

Clean Air- The reason why we would need clean air in a Zombie Outbreak is because any living thing such as animals and humans can't survive if they don't have clean air. So we can go to North Carolina where they have fresh clean air to survive.
