Deforestation refers to the long term loss. It occurs through human interactions with deforested areas. Deforestation could also result in landslides and avalanches. Trees sustain freshwater supplies, so if they are cut down, it affects the availability of one of life’s basic needs. Climate changes occur if forests are cut down, and the oxygen levels are also affected. Fewer trees also mean the loss of jobs for forest workers and there is a loss of future markets for ecotourism. Heavy rainfall and high sunlight damages the topsoil once the trees are gone and the forest takes much longer to regenerate and the land is unsuitable for agriculture.
