Reply To: Living or Biological Clarification
Thank you for your question. I think your son (for age almost 5) is expressing remarkably good knowledge and understanding. A perfectly logical argument can be made for paper being biological as it is made from from trees. It is quite arbitrary that we move it into the human-made category to express the role that humans played in producing it. Recognizing that everything human-made starts with resources from biological and/or natural earth categories should be a major point of this lesson.
I don’t know if this helps. Please ask further as you like.
