摘要：The man is directly connected with the natural environment and he changes and adapts it according to his needs. However, the Earth is one and only, this is where we live and where we should create for ourselves and for future generations such environmental conditions which will enable the man's survival. The present generation should not feel as an heir of the Earth from the previous generations, but it should borrow it and then give it back to the next generation with all its beauties and values and in a genuinely functional condition.
