As a small child, exactly when I cannot remember, I realised that in nature there are few peaceful deaths….birds, bees and butterflies do not grow old then lay down to shuffle off their mortal coils in the company of loving friends and family. Everything is a source of sustenance for other organisms from the bacteria and amoebae within our guts up through the branches of the tree of life. Brutal, and unemotional – but that is the way of the natural world it seems.
