Don't get it, its "critical" we learn about other animals so we can stick our noses into their existence when they've done and are doing fine without it?
Hell yeah, quite apart from animals like the manatee which would be probably extinct in florida without intervention and other places we act on the animals behalf (which is fine and what have you) we also help ourselves. We get anti hiv retrovirals from sea sponges, blood clotting agents from horseshoe crabs and a load of other stuff from poking around at shit. Studying how (captive) dolphins use sonar is ongoing to improve ultrasound machines to hopefully provide an inexpensive alternative to mri (oddly one of the main uses would be studying marine animals as getting them to hold still in an mri is apparently a bit of a fuck on)
