Long ago there was a village where there was no disease at all because there was no deforestation. There were many trees and the villagers understood its importance. They lived harmoniously.
One day a woodcutter came to the village. The villagers did not understand what was happening and the woodcutter decided to use this to his advantage. The village did not have a president.
So the wood cutter decided to be the village president and the people accepted him. But then he started to cut the trees there. If anyone opposed him, they would be locked up in jail. So no one opposed him. The village was soon struck by diseases.
