In the Context of High Human Density and Scarcity of Farm Land, how can we address Sustainable Management of Forests?

The forest being a habitat for several life forms and the primary producer in the food chain, plays so many important roles in human livelihood and welfare. Increasing population size has affected the quantity of forest trees, which has impacted the ecosystem of flora and fauna. Zero hunger means: creating more food, more food equals: more survivability, more survivability equals: increase in population. Don't get it twisted, I'm not saying zero hunger should not be address, am stressing the need to maintain the present population.
