有很多考古成果证明,森林是人类最早的栖身地。古书上说,“燧人钻木取火”。用木头烧火可以取暖,可以烧熟食物。当代很多学者的研究成果,一再说明森林改善了人类的生存条件,比如森林能够制造氧气并吸收二氧化碳、生产木材和果品,为人们创造就业机会,等等。不过,如果没有在林木稀少、氧气不足,同时干旱少雨因而不太适合人类生存的地方去生活、工作一段时间,那么,对森林的感觉就不会深刻。要真切认识森林对人类 There are many archaeological evidence that the forest is the earliest habitat of mankind. Ancient book said, “Suiman drilling wood fire.” Fire with wood can be warm, you can cook cooked food. The research results of many contemporary scholars have repeatedly stated that forests have improved the living conditions of mankind. For instance, forests can produce oxygen and absorb carbon dioxide, produce wood and fruit products, create employment opportunities for people and so on. However, if we do not live, work for a period of time in places where trees are scarce, oxygen is scarce, and at the same time it is less suitable for human existence due to drought, then the feeling of the forest will not be profound.
