"Lichens are a successful alliance
between a fungus and an alga. Each doing what
it does best, and thriving as a result of a
natural cooperation. They live as one organism,
both inhabiting the same body." A classic

"Many lichens are very sensitive to pollution in the air.
When there are too many harmful things in the air, lichens
die.
If you live where there are many lichens it probably means
the air is clean."
