"The reasons for this transformation were not workshops about reforestation, nor farmer manuals, nor “experts” from other countries paying farmers to plant trees. Rather, the change to a tree-planting culture occurred over a five-year relationship between Don Sebastian’s family and the Guatemalan technicians from the Alliance for International Reforestation, Inc. (AIR) or as it is known in Guatemala, “AIRES”"
"AIRES uses a five-year model, recognizing that it takes time to see the benefits of specific trees. The microbusinesses then succeed because neighbors have had time to observe the positive impact of growing trees that prevent mudslides and replenish soil."
Avot d'Rabbi Natan 31b
Rabbi Yohanan ben Zakkai used to say: If you have a sapling in your hand and are planting it, and someone should say to you that the Messiah has come, stay and complete the planting, and only then go to greet the Messiah.
