Biosphere consists of large amount of living species and individuals of various organisms. They live here long before human, they had created communities, societies and acquired colective memory to live over various life traps. During bilions years, there arised immense life net on the Earth, where organisms communicate each other, cooperate, fight against one another and so create one superorganism – biosphere.
That all happened without any credit of man. Man hasn't construct the biosphere, he don't understand it nor repair it. He can only accept it and cooperate with it. That Something, built and present without man contribution, is called wildness.
Something man didn't form, he shouldn't even destroy. First of all, wildness has its own value, for its beauty, persistence to live, for its perfection growing for bilions of years.
Wildness is the cultural heritage of the Earth, its like portrait of old master with no one to paint it again.
