Passage: Read the given passage and answer the questions that follow. Deforestation means cutting down or clearing forests on a large scale. It happens because of many human activities. People cut trees for wood, clear land for farming and use the space for cattle grazing. In some countries, forests are also destroyed for growing crops like oil palm or rubber. Sometimes, fires and logging make the forests thin and weak, which also leads to more deforestation. The results of deforestation are very serious. One major result is on the climate. Trees take in carbon dioxide, but when they are cut or burned, this gas goes back into the air and causes global warming. Another result is the loss of biodiversity. Many plants and animals live only in forests, and when forests disappear, these species may die out. Deforestation also brings harm to people. Without trees, soil becomes loose, which can cause floods and landslides that damage farms and houses. It also reduces the natural resources that people need for daily life. The significant damage caused by deforestation shows why it must be controlled. Question: Identify the tone of the passage.
