I think s to 24 hours program cakes can only change the conditions of the division and if I such channels as Discovery Channel and his sometimes insufferable advertising and propaganda films see where under the guise of "documentary" part of the same dirt is wasted as elsewhere , I see only one chance in good documentaries on the species, etc. ..
My favorite times just out of my head:
almost all of Marianne Chaud
Al Oud of Fritz Baumann
and many more ...... it is good but they still slots are scarce.
