Forestry
Forests are very important for the world today. Much of the water cycle and carbon cycle goes through forests. Many of them are disappearing because people destroy them for firewood or to make farms. A forester makes sure the forest and all the animals that live there are healthy.  Foresters also make sure the forest is in good condition for people to use.  They makes sure that forests are not destroyed by wildfires before they are ready to use for timber production (cutting down trees to use the wood).
