Deforestation is when forests are destroyed by cutting trees (logging) and not replanting them. Sometimes deforestation happens when people change lands into farms, ranches and cities. The most common cause for deforestation is obtaining wood and fuel. This way, the homeland of many animals disappears, leading to their undoubted death.
Causes of deforestation[change | change source]
As we know, deforestation is the removal of trees. As the population grows, people need to remove more trees. They use the land to make farms. They also use the wood from the trees as lumber to make buildings and other things, or they burn the trees as firewood. Sometimes, forests are lost because people want to make cities bigger; this means building roads and buildings on the land where the forests are. Sometimes deforestation may be caused due to increase of population.
Forests have the following functions:-
- regulation of the water cycle
- production of soil
- providing habitat for animals
- providing most of our oxygen
- maintain the oxygen and carbon dioxide (CO2)
- balance in the atmosphere
- regulation of temperature
- prevention of soil erosion
- tree diseases 
Trees are also important for carbon sequestration. When the trees burn or rot, the carbon in them returns to the atmosphere in the form of carbon dioxide. Since carbon dioxide is a greenhouse gas, deforestation causes global warming. Tropical deforestation is responsible for about 20% of world greenhouse gas emissions.
