Deforestation
What is causing this process and how can it be reversed?

2. Deforestation is conversion of forested land areas to non-forest land
The non-forseted land is used for arable land (farming or grazing) or urban use (bulidings, homes, etc)
Even with reforestation, biodiversity (natural environment) loss may still occur
Deforestation can be natural (lightning, wildfires)
Usually deforestation is man made

3. Man-made reasons
Clearing land to graze cattle
Developers who want to urbanize areas
Logging/wood industry (wood products)
Indigenous farmers who use a technique called slash & burn
Slash & burn is cutting down trees & then burning them
Ash can be a nutrient for the ground to grow crops more quickly

4. Problems with deforestation
Trees breathe in CO2 (greenhouse gas) and breathe out oxygen, less trees = more pollution
Natural wildlife habitats are destroyed
Absence of trees affects the water in the ground
Landslides – no natural barrier to stop mud with less trees on hillside
How people are helping
Planting more trees
China requires every citizen age to plant three trees a year
Less consumer demand for wood products
