Forestry
 Forests are very important for the world today. Many of them are disappearing because there are so many people in the world. A forester has the job of making sure that the forest and all the wildlife that lives there is healthy. They are very important today because humans produce a lot of carbon dioxide and the trees in forests help to turn this back into oxygen which we breathe to live from. In forestry professionals look after forests and advise government on artificial forestry. Many universities offer courses after higher education in zoology and botany.
