Very good article @agmoore, this post touches on several interesting points, I had forgotten about the seal hunt, I even didn't remember the reason why they were persecuted by our species, but you very well mentioned that it was for the skin and, above all, for the oil. On the other hand, when a species is eliminated from a habitat and then wants to be incorporated again is quite difficult, all this depends a lot on the animal, as some adapt quickly and others may take longer, so there are species that have or are limited to a certain geographic range. It is very unfortunate to see such large and beautiful animals as orcas and whales being trampled by man. As an addition to the latter, today it has become common to see men and women kissing or touching whales when they emerge in the ocean near their boats, this is something that should not be done because humans can transmit pathogens that can endanger the lives of whales, this is being denounced by many biologists and environmental experts on the subject.
Touching on a somewhat different point but that has to do with animals, yesterday I saw a news item where rhinos are having their horns removed in a controlled manner to prevent hunters from killing them, what they are doing is removing their horns and replacing them with a plaster prosthesis, although the horn will grow back, but this measure prolongs the life of the animal and it can manage to reproduce. It is unfortunate that this has to be done, but it is the only way out that some African governments are trying to reduce the slaughter of these animals.
This publication you made is very complete, I have nothing more to add and I can only congratulate you for your impeccable writing, good health and success for you and your family @agmoore.
