   Dear mister Mariano,

   Regarding to the latest episode I have been watching on the Dutch/Belgium series about the voyage of Darwin. I am writing you this e mail. I am a woman fromHolland and my parents have been sailing our whole lives, while we were kids I have sailed in Danmark and the South of France a lot. Therefore I have a very strong opinion about the sealife. I have heared your opinion about the wales in the world’s ocean and would like to emphasize that there is not only the noice under water which is disturbing the wales dolphins and other sealife!
   As a kid i learned to navigate with paper maps soon due to modern tecnologie the old fashion way of navigation was taken over by the use of AP navigators. Sailing in Danmark we realised that our depth meters were strongly diffused /disturbed by gellyfish gathered inlarge groups. So it seems the gellyfish are a sort of sea bottom on which our modern sonar equipment is responding!

   These machines ( AP navigators combined with depth sonars) used to communicate by the human device are depending on one thing. Satellites which are circling around our globe and sending NOISE which humasn cannot hear. But liks gelyfish a dolphin uses a total different means of hearing therefore they can communicate while being thousands and thousends of yards away from eachoter. BUT while trying to communicate whales and dolphins brown fish and other sealife get very much disturbed by the thousands of sattelites swerming around our globe. The creatures have lost there ways of communicating about plankton and the miniscule animals they eat and good resting places to rest and eat.

   This al is in my opinion with my relative biologie knowledge but my sailing experience and knowledge of the sea one of the biggest threats for all the animals which are about to extinct. The constant bleeping of the many telephone sattelites are not only a burdon but also make it impossible for them to reach one another. They get stressed out and have no means of telling so to speak each other about good hunting /eating places ore places to give save birth. Compare this knowledge with the sound a dolphin makes when caught up in a tuna net while casping for breath. The family will try to set one of there members free and while the dolphin is desperately trying to get loose. The group reacts to this panic noise! If however a whale is stressed ( last 40-50 years increasingly) it will produce the wrong tale strory what we humans call singing of whales.

   Please explore my opinion further before the sea is left empty, and we will find no more of these earth inhabitants which we all make life and communications needed to live that difficult with sonar noice of our simple means to communicate (sattelites, telephone, AP navigators in various boats and planes.)

   With kind regards and the respect,

   Marianne Rus
