Why is it important to save endangered species

Well, mostly is important to save endangered species cuz mostly we the ones that endangered them in the first place.  So we have to help to fix some of the mess we made.  I didnt do it, but its still up to me to help.  Sometimes though, a species is endangered because it cant change.  That has been happening forever and will keep happening . It makes way for new species.  Sometimes, we have to let them go.
