How to prevent forest fires, once and for all

I have long been concerned about two things related to our green riches of the forest: selling in China and fires.
The forest is burning because trees grow very close to each other. What if you cut and sell the timber, leaving, for example, every 5th tree? So it is possible to do away with fires and still earn the state.
What do you think?
