Now in some places of our country， a number of people have been cutting down the trees in the forests because they need wood and more farmland。 The areas of forests are getting smaller and smaller。 Some scientists say that there will be no vast forests in 20 or 30 years。 It is really a terrible thing。 Where the forests disappear， dust storms will occur occasionally。 The weather will get hot and dry。 The whole earth will become a big desert。 A lot of plants and animals will disappear。Crops will not grow anywhere。 Life will be difficult for everyone。 The human beings will be punished for their forest-destroying activities。
Therefore， we should realize the importance of taking care of our forests。 We should do our best to protect our living environment and keep our mountains green，the water clean， and the sky blue。
