This film presents three possible techniques or methods that make it possible to meet the growing demand for wood without the country becoming a desert: spontaneous reforestation, carried out by the country's youth, technical and commercial plantation, and the comprehensive use of forests. . Scientists and farmers, peasants and young people express their opinions on these techniques and on the critical situation that the country is going through. The "lone witness", a tree abandoned to its fate in the middle of infertile pastures in the Puriscal area, leaves graphic testimony about the felling of trees taken to the absurd.
