Empathy is the reason most people want to prevent an entire species from going extinct. It doesn't matter if the extinction is due to evolution in action, most people still feel bad about seeing a species die out. Most of the time, however, it is not evolution in action, but a direct result of humanity's detrimental effect on the planet, so it then becomes our duty to try to stop the extinction from happening.
