Controlled Burn
Forest fires kill animals, trees, plants, and sometimes people. They also destroy houses, vehicles, and roads.
In order to prevent the spread of forest fires, firefighters start "controlled fires".
Deforestation
Deforestation is the permanent removal of forests.
Forests are removed to provide land for farms, houses, factories, stores, and roads. Forests are also cut down so the wood can be sold for profit.
Child's Tree House
This girl is in a tree house. A tree house is a small room built around the trunk of a tree. It usually rests on several strong branches.
Children climb up the trunk of the tree to enter the tree house. Sometimes they nail pieces of wood to the trunk of the tree to making climbing easier.
