Geosonnet 29

The scent from Madagascar’s fine perfume
Enhances ice cream, fragrances the bath
Beyond this orchid spice a shadow looms:
A mass extinction’s lethal aftermath.
When sulfur, carbon oxidize in air
A surplus of ionic hydrogen
In rain burns plants, and leaches soil bare
Wrecked ecosystems cannot rise again.
Vanillin burns as microbes decompose
At high pH, vanillic acid’s made.
With only aldehyde, one could propose
An acid landscape, compounds undecayed.
   Pollution in the first Triassic rain
   Prevented life from sprouting up again.
