Did those trees, before there were decomposers, have access to nitrogen fixing bacteria? Where were they getting ammonium and nitrate?
Just stuff built up from lightning, nitrogen and oxygen?
Edit: Looks like land dwelling soil forming bacteria started in the Cambrian. Then, in the Ordovician the first land plants. Then, in the Silurian vascular plants and trees appeared.
And in 4 billion years, that layer of microplastics will have condensed down into fuel for the next creatures to annihilate their atmosphere with. Circle of life.
