Soil microorganisms are a pest,
Releasing petagrams of C O two
As a by-product of what they digest.
Whilst nitrogen deposits do accrue,
More harmful greenhouse gases will ensue.
But if the soil diversity is great,
Small animals can then graze their way through
These microorganisms at a rate
That may reduce the feedback before it’s too late.
This is a Spenserian stanza, written about this study, which investigates how diverse soil communities can help offset the impacts of global warming.
