How society should assign value to human life? ?

Well right at the moment society is saying babies and kids are more important cuz we have to live our lives where as the adults have lived there lives and such but the problem with this is kids need grownups around to protect,care,feed, and love us without grownups babies and MOST kids will die.

so what i think should happen is BOTH kids/teenagers under the age of 18 and grownups should be prioritized eaqully cuz neither one can survive without the other. if all grownups di so will the children and if all the kids die once grownups die thatll be the end of humans and the only thing on this planet will be animals and plants. 
so long story short all human life is important and should be treated equal
