I say otherwise because,

1) Backhaus clearly has zero experience with marine mammal health or stranded marine mammals. Although he is getting information from many sources, he has decided to amplify the ones that want to attempt to rescue the whale. He is not only a politician, but is the longest serving minister in the area. He's a good politician. He changed course only after the demonstrations started and started to support the private rescue effort

2) The primary veterinarian for the private initiative (Kirsten Tönnies) is a small-animal vet (i.e, cats and dogs). She also does not (as far as I know) have any experience with marine mammal health or marine mammal strandings.

3) The other big vet voice is Janine Bahr. She does have marine mammal experience, but mainly smaller dolphins. She is also very much an activist and very media-savvy.

4) Every organization of marine mammal researchers that do have experience responding to entangled and stranded large whales have released statements that this whale is very unlikely to survive and should be left to die in peace. That includes the International Whaling Commission (multiple times), Whale and Dolphin Conservation, Institute of Terrestrial and Aquatic Wildlife Research, Deutsches Meeeresmuseum, and British Divers Marine Life Rescue. That makes for hundreds of thousands of person hours of experience.

5) The whale still has fishing line entangled in its baleen that it has likely swallowed.

6) It has suffered severe osmotic shock being the much less saline Baltic Sea.

7) It has suffered weeks of acoustic trauma being surrounded by loud boats and large machines as well as the stress of being handled by so many people.

8) It has suffered weeks of sun and epidermal damage.

I love whales and dolphins as much if not more than most people.I would love for this animal to survive. However, I also do not want to cause it more trauma than it has already experienced if it is on its way out.

I know that experts devote their lives to these animals. It is difficult to hear things that don't want to, but that doesn't mean we can pick an choose the opinions that we like. If we don't have firsthand knowledge, we should try to evaluate the sources and pay attention to the ones that actually have the experience, not the ones that either are saying what we want to hear or are loudest.

Also, be careful about people claiming to be experts who also advertise themselves and come with cameras (e.g., Lehman). Check their actual background in the subject and see if they are really trying to help or just self promote.
