If I have learned anything in my years it’s that there is no inherent dignity in a Death of any kind. Sure we try to inject some into the process but we never really succeed because there wasn’t any there to begin with. Nobility maybe, compassion probably, but dignity…no.
As the gardeners of this great big Gadren that was gifted to us we can address the different injustices that we perceive. In fact I would encourage you to address it to the best of your ability. Tear down some of the vine if you wish to give the tree a fighting chance. Perhaps erect a small fence or other barrier around the property to reduce the chance of predation by domesticated animals.
I can see how you might feel discouraged by these things but that can be used as a motivation instead of a defeat. Predation is a constant act in a world where competition is the natural order and modern humans aren’t used to losing in that game despite the fact that bacteria/viruses, exposure, accidents, and predation are taking us out all the time too. Please remember, nay believe, that Life(in all it’s forms) is worth protecting, learning about, and propagating despite the fact that Death exists.
