The world's forests become smaller and smaller.People are still cutting down the trees.Why is this happening？There are two reasons－land and wood.
People need land for animals and crops.And people want wood.Japan，Europe and North America need wood.There，it is used for buildings or it is made into furniture (家具)．
But most places from the forests are not good for animals or crops.The soil(土壤) in the forests is very thin.When trees are cut down，the soil is washed away by the rain or blown away by the wind.Soon there is nothing but sand.Then more land will be needed and more trees will be cut down.
Who can we blame(责备) for the lost forests？The answer is all of us.There are too many people in the world.Look around.Maybe you are listening to the loudspeaker or sitting on a chair.They are made of wood.
