Main causes of wood cutting in Thailand. Most of logging are wood cutting to do business such as paper making, home builders, and smugglers reserved to be sold. People who smuggle wood, because they need wood to go to benefit themselves without planting themselves and want the money from selling wood to be used in everyday life. From these actions can cause flooding, as there are no tree roots to absorb water, and landslides because of the soil erosion. Because there are no trees that adhere to the land, it is like a weir to help slowdown of water before coming down into the community area. The reduction in the tree makes the wood expensive. So people turned to smuggle wood because they did not pay for purchase (Allen, 2017). It is a factor that contributes to the decline in the number of forests and contributes to a lot of wisdom.
