They have to be managed in such a way that they meet the well being of the community; once such a principle is complied with, their use may also suit individual interests. Adverse influence on eco-systems has to be avoided and in general a sustainable development has to be guaranteed. In view of the paramount necessity to safeguard the climate, a high degree of protection for the whole environment shall have to be ensured.
