Lichens are important in many ways:
# Lichens are sensitive to pollution in the air and can tell us if the air is clear and clean.
# Drug companies make antibiotics from lichen substances.
# Some lichens make nitrogen in the air usable to plants.
# Lichens are homes for spiders, mites, lice and other insects.
# Lichens can be used as a natural dye to color wool.
# People eat lichens (careful – a few are poisonous).
What could possibly be more fun than Lichens?
