Indirect Connection/Support: Detritus and Death
There is a lot of support indirectly and perhaps unconsciously given to the world around us. In Eden I witnessed a Robin picking up crumbs that I had just swept from my knee during a quick lunch in the woods.
The pinnacle of unintended support and connection comes after death. Our bodies return to the earth and can support other lifeforms.
But this is not the only way dead lifeforms can support the living. Humans make various use of dead lifeforms as raw materials for construction, and other supportive functions for life.
