Since the earliest times,trees have always been very useful and important to man who made use of them in many ways.Even today trees continue to serve man in so many ways.
Trees provide man with fruits and building materials in the form of wood.Without trees it would be impossible to build houses,boats and even bridges.Furniture such as tables,chairs and beds is made of wood.
In the tropics where it is very hot throughout the year,trees protect man from the terrible heat.They are also useful in preventing good and rich top soil from being washed away during heavy rains which are so common in the tropics.
If there were no trees or vegetation of some kind to hold back the soil with their roots,heavy rain would wash away the rich surface soil that is so important and necessary to agriculture.The result is that the land becomes a desert.
There are so many desert areas in the world.A long time ago these desert areas must have been very rich fertile areas,but since our ancestors in the distant past did not have enough knowledge about science of nature,they cut down all the trees in the areas where they lived and never planted new ones.By and by,the rich surface soil was blown away and washed away by strong winds and heavy rains.In the end the land was turned into useless deserts where nothing could grow.

在早些年,树对于在很多方面利用它们的人来说是非常有用和重要的.甚至是现在,树也仍然在许多方面服务人们.
树提供给人们水果和作为建筑材料的木头.没有树,就不可可能建造房子,船甚至是桥梁.像桌子,椅子和床这样的家具也是由木头制成.
在那些全年都非常炎热的热带雨林,树木保护着处于高温中的人们.它们也能有效地防止上层的肥沃土壤被暴雨冲走这一热带雨林的常见现象.
它们对于农业的重要性和必要性在于如果没有树木和某些蔬菜用它们的根抓住土壤,大雨将会冲走表层的肥沃土壤,导致陆地变成荒漠.
世界上有许多的荒漠地区.很久以前这些荒漠地区一定是非常富饶的地区,但由于我们的祖先们没有足够的关于自然科学的知识,他们砍掉了他们居住范围内所有的树,却从来不种树.日复一日,那肥沃的表层土壤被大风吹走,被大雨冲走.最后这些土地变成了不能生长植物的没用的荒漠.
