Forests are one of the main elements of our natural heritage. The decline of Europe‘s forests over the last decade and a half has led to an increasing awareness and understanding of the serious imbalances which threaten them. (46) European countries are becoming increasingly concerned by major threats to European forests, threats which know no frontiers other than those of geography or climate: air pollution, soil deterioration, the increasing number of forest fires and sometimes even the mismanagement of our woodland and forest heritage. There has been a growing awareness of the need for countries to get together to coordinate their policies. In December 1990, Strasbourg hosted the first Ministerial Conference on the protection of Europe‘s forests. The conference brought together 31 countries from both Western and Eastern Europe. (47) The topics discussed included the coordinated study of the destruction of forests, as well as how to combat forest fires and the extension of European research programs on the forest ecosystem. The preparatory work for the conference had been undertaken at two meetings of experts. Their initial task was to decide which of the many forest problems of concern to Europe involved the largest number of countries and might be the subject of joint action. Those confined to particular geographical areas, such as countries bordering the Mediterranean or the Nordic countries therefore had to be discarded. However, this does not mean that in future they will be ignored.
As a whole, European countries see forests as performing a triple function: biological, economic and recreational.(48) The first is to act as a “green lung” for our planet: by means of photosynthesis, forests produce oxygen through the transformation of solar energy, thus fulfilling what for humans is the essential role of an immense, non-polluting power plant. At the same time, forests provide raw materials for human activities through their constantly renewed production of wood. (49) Finally, they offer those condemned to spend five days a week in an urban environment an unrivalled area of freedom to unwind and take part in a range of leisure activities, such as hunting, riding and hiking. The economic importance of forests has been understood since the dawn of man—wood was the first fuel. The other aspects have been recognized only for a few centuries but they are becoming more and more important. Hence, there is a real concern throughout Europe about the damage to the forest environment which threatens these three basic roles.
The myth of the “natural” forest has survived, yet there are effectively no remaining “primary” forests in Europe.All European forests are artificial, having been adapted and exploited by man for thousands of years. (50) This means that a forest policy is vital that it must transcend national frontiers and generations of people, and that it must allow for the inevitable changes that take place in the forests, in needs, and hence in policy.
欧洲国家越来越关注对欧洲森林的主要威胁, 这些威胁除了地理或气候之外不分国界: 空气污染, 土壤恶化, 日益增多的森林火灾, 有时甚至是我们对林地和森林遗产管理不善都造成了对森林的威胁。
讨论的主题包括对森林破坏的协调研究、 如何与森林火灾作斗争以及欧洲关于森林生态系统研究项目的扩展。
第一是充当我们这个星球的“绿色肺”: 森林通过光合作用, 即: 通过转化太阳能产生氧气, 为人类充当了一个巨大无污染的发电厂。
最后, 对于那些被判每周在城市环境中度过五天的人, 森林为他们提供了一个无与伦比的自由空间, 让他们可以放松下来, 参加一系列的休闲活动, 比如打猎、 骑马和徒步旅行。
这意味着森林政策至关重要, 它必须超越国界和每一代人, 它必须因森林而变, 因需求而变, 甚至因政策本身而变。
