You are missing the point that in order to save species, often individual animals need to be killed. Even in the modern era of DNA sequencing, museum collections tell us much about animals and even work as a sort of time machine for sequencing. I recently went to a seminar about a project that was studying the microbiomes from the gut contents of 19th century preserved animals in order to see if they were different from modern ones. This will help us know to what degree the greater human impact in the 21st century is affecting the health of wildlife. If people hadn't collected animals in the 19th century how could we do this? How will people in the future do the same if we don't collect animals now?
