This is where humans survive easiest and lots of forest. Most human population lives in the same narrow part of climate envelope around globe. Can humans survive on land that does not include trees and symbiotic microbes? Historically, what did people and wildlife do if they found themselves living on lands without trees? - No, migrate during winter or droughts when no trees grew on land (as it would provide no survival resources). No trees means no fresh drinking water. Why is human food security linked to forests? NOTE: Look at the CIFOR Forest Blog and FAO video for today's class - Forests are essential for animals and wildlife ecosystem, without forests much of animal species will not exist.
