Think of it more like a filter than something blocking the signal. It can help clean the signal from some of the more harmful stuff coming through. Like other filters it can get clogged in time.

There is a design science in this area called Biogeometry which can help correct big issues. Think of these like something taken from permaculture without any context. The applicability will vary.

I’m also still just a student in adjacent disciplines to Biogeometry so I only know a little and have little experience using some of the common tools.
